Project description

Setting-up a demonstration server for Alignak monitoring framework …

This repository contains many stuff for Alignak:

demo configuration to set-up a demo server (the one used for http://demo.alignak.net)
some various tests configurations (each having a README to explain what they are made for)
scripts to run the Alignak daemons for the demo server (may be used for other configurations)

What’s behind the demo server

This demonstration is made to involve the most possible Alignak components on a single node server.

To set-up this demo, you must:

install Alignak
install Alignak backend
install Alignak Web UI
install Alignak modules (backend and nsca)
install Alignak checks packs (NRPE, WMI, SNMP, …)
import the configuration into the backend
start the backend, the Web UI and Alignak
open your web browser and rest for a while looking at what happens :)

Note: it is possible to run Alignak without the backend and the WebUI. all the monitoring events are then available in the monitoring logs but, with this small configuration, one will loose the benefits ;)

The monitored configuration

On a single server, the monitored configuration is separated in four realms (All, North, South and South-East). Some hosts are in the All realm and others are in the North and South realm, both sub-realms of All realm. The South-East realm is a sub-realm of South and it also contains some hosts.

The All realm is (let’s say…) a primary datacenter where main servers are located. North and South realms are a logical group for a part of our monitored configuration. They may be seen as secondary sites.

According to Alignak daemon logic, the master Arbiter dispatches the configuration to the daemons of each realm and we must declare, for each realm:

a scheduler
a broker
a poller
a receiver (not mandatory but we want to have NSCA collector)

In the All realm, we find the following hosts:

localhost
and some others

In the North realm, we find some passive hosts checked thanks to NSCA.

In the South realm, we find some other hosts.

Requirements

Mandatory requirements

You will need some requirements for setting-up this demonstration:

# Update your server
sudo apt-get update
sudo apt-get upgrade

# Install git and python
sudo apt-get install git
sudo apt-get install python2.7 python2.7-dev python-pip

# Needed for the PyOpenSSL / Cryptography dependencies of Alignak
sudo apt-get install libffi-dev libssl-dev

Optional requirements

The scripts provided with this demo use the screen utility found on all Linux/Unix distro. As such:

sudo apt-get install screen

Some screen hint and tips:

# Listing the active screens
screen -ls

# Joining a screen
screen -r alignak-backend

# Leaving a screen (without killing it)
screen -r alignak-backend
Ctrl a+d

# Switching between active screens
Ctrl a+n

Note: It is not mandatory to use the provided scripts, but it is more simple for a first try;)

Setting-up the demo

We recommend having an up-to-date system;)

sudo apt-get update
sudo apt-get upgrade

We also recommend using the most recent pip utility. On many distros pip is currently available as version 8 whereas the version 9 is available:

sudo pip install --upgrade pip

1. Get base components

Note that all the Alignak components need a root account (or sudo privilege) to get installed.

Alignak framework

mkdir ~/repos
cd ~/repos

# Alignak framework
git clone https://github.com/Alignak-monitoring/alignak
cd alignak
# Install alignak and all its python dependencies
# -v will activate the verbose mode of pip (not mandatory...)
sudo pip install -v .

# Create alignak user/group and set correct permissions on installed configuration files
sudo ./dev/set_permissions.sh

Alignak backend

# Alignak backend
sudo pip install alignak-backend
# To allow alignak user to view the log files
sudo chown -R alignak:alignak /usr/local/var/log/alignak-backend/

Note that you will need to have a running Mongo database. See the Alignak backend installation procedure if you need to set one up and running.

An excerpt for installing MongoDB on an Ubuntu Xenial:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6
echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/testing multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list
sudo apt-get update
sudo apt-get install -y mongodb-org
sudo service mongod start

An excerpt for installing MongoDB on a debian Jessie:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6
echo "deb http://repo.mongodb.org/apt/debian jessie/mongodb-org/3.4 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list
sudo apt-get update
sudo apt-get install -y mongodb-org
sudo service mongod start

Alignak backend importation script

Alignak ships a flat-file configuration importation script to feed the Alignak backend. This script is used to parse, check and import a Nagios-like configuration into the Alignak backend.

Note that it is not mandatory to install and use this script because the Alignak WebUI allows to create all the monitored objects configuration from scratch :)

For this demo, we will install and use the alignak-backend-import script? So let’s install it

# Alignak backend importation script
sudo pip install alignak-backend-import

Alignak webui

# Alignak webui
sudo pip install alignak-webui
# To allow alignak user to view the log files
sudo chown -R alignak:alignak /usr/local/var/log/alignak-webui/

2. Install check plugins

Some extra installation steps are still necessary because we are using some external plugins and then we need to install them.

The NRPE checks package requires the check_nrpe plugin that is commonly available as:

sudo apt-get install nagios-nrpe-plugin

The monitoring checks package requires some extra plugins. Installation and configuration procedure is available here or on the Monitoring Plugins project page.

You may instead install the Nagios plugins that are commonly available as:

sudo apt-get install nagios-plugins

As of now, you really installed all the necessary stuff for starting a demo monitoring application, 2nd step achieved!

3. Get extension components

Note: If you intend to set-up your own monitoring configuration, you are yet ready!

The next three chapters explain how to install Alignak modules, checks and notifications for the demo server.

Note because most of the checks packs are able to create the templates, commands,… directly into the Alignak backend during the installation processyou should start the Alignak backend before installing the checks packs and modules ;) See later in this document how to start the Alignak backend…

To avoid executing all these configuration steps, you can install a all-in-one package that will install all the other packages thanks to its dependencies:

# Alignak demo configuration
# IMPORTANT: use the --force argument to allow overwriting previously installed files!
sudo pip install alignak-demo --force

# Re-update permissions on installed configuration files
sudo ./dev/set_permissions.sh

mkdir ~/demo
cp /usr/local/var/libexec/alignak/*.sh ~/demo

Note: it is the easisest solution to quickly have a running demo server, but it will miss all the important configuration part for a monitoring system :)

Note: If you install the alignak-demo package, go directly to the step 5.

Modules

Execute these steps only if you did not installed `alignak-demo`

Get and install Alignak modules:

# Those two modules are "almost" necessary for the essential alignak features
# If you do not install this module, you will not benefit from the Alignak backend features (retention, logs, timeseries, ...)
sudo pip install alignak-module-backend
# If you do not install this module, you will miss a log of all the alignak monitoring events: alerts, notifications, ...
sudo pip install alignak-module-logs

# Those are optional...
# Collect passive NSCA checks
sudo pip install alignak-module-nsca
# Write external commands (Nagios-like) to a local named file
sudo pip install alignak-module-external-commands
# Notify external commands though a WS and get Alignak state with your web browser
sudo pip install alignak-module-ws
# Improve NRPE checks
sudo pip install alignak-module-nrpe-booster

# Note that the default module configuration is not suitable, but it will be installed later...

Notifications

Execute these steps only if you did not installed `alignak-demo`

Get notifications package:

# Install extra notifications package
sudo pip install alignak-notifications

Note that this pack requires an SMTP server for the mail notifications to be sent out. If none is available you will get WARNING logs and the notifications will not be sent out, but the demo will run anyway :) See later in this document how to configure the mail notifications…

Checks packages

Execute these steps only if you did not installed `alignak-demo`

Note that most of the checks packs are able to create the templates, commands,… directly into the Alignak backend during the installation process. To allow this creation, your Alignak backend must be running and available on its default interface (http://127.0.0.1:5000).

Get checks packages:

# Install checks packages according to the hosts you want to monitor
# Checks hosts thanks to NRPE Nagios active checks protocol
sudo pip install alignak-checks-nrpe
# Checks hosts thanks to old plain SNMP protocol
sudo pip install alignak-checks-snmp
# Checks hosts with "open source" Nagios plugins (eg. check_http, check_tcp, ...)
sudo pip install alignak-checks-monitoring
# Checks mysql database server
sudo pip install alignak-checks-mysql
# Checks Windows passively checked hosts/services (NSClient++ agent)
# As of now, use ==1.0rc1 to get the correct version
sudo pip install alignak-checks-windows-nsca
# Checks Windows with Microsoft Windows Management Instrumentation
sudo pip install alignak-checks-wmi

# Note that the default packs configuration is not always suitable, but it will be installed later...

# Restore alignak user/group ownership and set correct permissions on installed configuration files
sudo ./dev/set_permissions.sh

  alignak-webui (0.8.8.1)

As of now, you installed all the necessary Alignak stuff for starting a demo monitoring application, 3rd step achieved!

4. Configure Alignak and monitored hosts/services

Note: you may configure Alignak on your own and set your proper monitored hosts and declare how to monitor them. This is the usual way for setting-up your monitoring solution… But, as we are in a demo process, and we want to make it simple, this repository has a prepared configuration to help going faster to a demonstration of Alignak features.

For this demonstration, we imagined a distributed configuration in three realms: All, North and South. This is not the default Alignak configuration (eg. one instance of each daemon in one realm) and thus it implies declaring and configuring extra daemons. As we are using some modules we also need to declare those modules in the corresponding daemons configuration. Alignak also has some configuration parameters that may be tuned.

If you need more information about alignak configuration.

To avoid dealing with all this configuration steps, this repository contains a default demo configuration that uses all (or almost…) the previously installed components.:

# Alignak demo configuration
cd ~/repos
git clone https://github.com/Alignak-monitoring-contrib/alignak-demo

Some extra configuration files are shipped in the alignak_demo/etc directory. You may copy those files to replace the default Alignak shipped configuration, but, as we will use the Alignak backend, most of the configuration will stay in the backend database and copying the files is not necessary.

cp -R ~/demo/alignak-demo/alignak_demo/etc /usr/local/etc/alignak

Some utility scripts are also shipped in the alignak_demo/libexec folder. For ease of use, you may copy those scripts in your home directory.

mkdir ~/demo
cp /usr/local/var/libexec/alignak/*.sh ~/demo

As explained previously, the shell scripts that you just copied use the screen utility to detach the process execution from the current shell session.

As of now, Alignak is configured and you are ready to run, 4th step achieved!

5. Configure, run and feed Alignak backend

It is not necessary to change anything in the Alignak backend configuration file except if your MongoDB installation is not a local database configured by default. Else, open the /usr/local/etc/alignak-backend/settings.json configuration file to set-up the parameters according to your configuration.

start / stop the backend

Run the Alignak backend:

cd ~/demo

# Detach a screen session identified as "alignak-backend" to run the backend processes
sudo ./alignak_backend_start.sh

# This will run the alignak-backend-uwsgi in a screen session. If you do not mind about a
# backend screen, you should run: sudo alignak-backend-uwsgi
# Using sudo because we assume that you are logged with a user account that is not the alignak one

ps -aux | grep uwsgi-
    root 25193  0.5  0.4 238604  72044  9  I+J  10:13AM 7:10.69 uwsgi --ini /usr/local/etc/alignak-backend/uwsgi.ini
    root 25191  0.0  0.0  17096   2076  9  I+J  10:13AM 0:00.00 /bin/sh /usr/local/bin/alignak-backend-uwsgi

    root 25196  0.0  0.4 190304  60708  9  S+J  10:13AM 0:41.29 uwsgi --ini /usr/local/etc/alignak-backend/uwsgi.ini

# Joining the backend screen is 'screen -r alignak-backend'
# Ctrl+C in the screen will stop the backend
# kill -SIGTERM `cat /tmp/alignak-backend.pid`

# The alignak backend writes some logs as a Web server does
tail -f /usr/local/var/log/alignak-backend-error.log
tail -f /usr/local/var/log/alignak-backend-access.log

The alignak backend runs thanks to uWSGI and its configuration is available in the /usr/local/alignak-backend/uwsgi.ini where you can define the log files location. You can also configure the Alignak backend to send its internal metrics to a Graphite timeseries database.

Note that a Grafana dashboard for the Alignak backend is available in the /usr/local/etc/alignak/sample/grafana directory created when you installed the alignak-demo package;)

Feed the backend

Run the Alignak backend import script to push the demo configuration into the backend:

# Import the demo configuration into the backend
cd ~/repos/alignak-demo
alignak-backend-import -d ./alignak_demo/etc/alignak-backend-import.cfg

Note: there are other solutions to feed the Alignak backend but we choose to show how to get an existing configuration imported in the Alignak backend to migrate from an existing Nagios/Shinken to Alignak.

Once imported, you can check that the configuration is correctly parsed by Alignak:

# Check Alignak demo configuration (from the git repo)
alignak-arbiter -V -a ~/repos/alignak-demo/alignak_demo/etc/alignak.cfg

Note because the backend is now started and available, there is no more ERROR raised during the configuration check! You may still have some information about duplicate elements but nothing to take care of…

As of now, Alignak is ready to start… let us go!

6. Run Alignak

Run Alignak:

cd ~/demo

# Define where to find the Alignak configuration file
# As default, it will use the */usr/local/etc/alignak/alignak.cfg* file. If you copied the
# files to the default location, it is not necessary to define those variables
export ALIGNAKCFG=~/repos/alignak-demo/alignak_demo/etc/alignak.cfg
export ALIGNAKCFG=~/repos/alignak-demo/alignak_demo/etc/daemons

# For FreeBSD users:
setenv ALIGNAKCFG /root/repos/alignak-demo/alignak_demo/
setenv ALIGNAKDAEMONS /root/repos/alignak-demo/alignak_demo/etc/daemons/

# Detach several screen sessions identified as "alignak-daemon_name"
./alignak_demo_start.sh

# Stopping Alignak is './alignak_demo_stop.sh'

Log files

Each Alignak daemon has its own log file that you can find in the /usr/local/var/log/alignak folder. If any error happen there will be at least an ERROR log in the corresponding file. You can tail the log files or use more sophisticated tools like multitail to stay tuned with Alignak activity

# Using tail
tail -f /usr/local/var/log/alignak/*.log

# Using multitail
sudo apt-get install multitail

multitail -f /usr/local/var/log/alignak/arbiterd.log\
          -f /usr/local/var/log/alignak/brokerd.log \
          -f /usr/local/var/log/alignak/brokerd-north.log \
          -f /usr/local/var/log/alignak/brokerd-south.log \
          -f /usr/local/var/log/alignak/pollerd.log \
          -f /usr/local/var/log/alignak/pollerd-north.log \
          -f /usr/local/var/log/alignak/pollerd-south.log \
          -f /usr/local/var/log/alignak/reactionnerd.log \
          -f /usr/local/var/log/alignak/receiverd.log \
          -f /usr/local/var/log/alignak/receiverd-north.log \
          -f /usr/local/var/log/alignak/schedulerd.log \
          -f /usr/local/var/log/alignak/schedulerd-north.log \
          -f /usr/local/var/log/alignak/schedulerd-south.log

Tracking the plugin execution

When setting up a new configuration and installing or testing plugins it may be interesting to have information about the launched check plugins and the returned results. Alignak allows to add information in the log files about plugins execution:

# Set and export an environment variable
export TEST_LOG_ACTIONS=1

This variable make some more logs in the log files for: - launched command for the check plugins - check plugins result - notification commands

Monitoring events

You can follow the Alignak monitoring activity thanks to the monitoring events log created by the Logs module. You can tail the /usr/local/var/log/alignak/monitoring-logs.log file:

Monitoring events configuration

This file is a log of all the monitoring activity of Alignak. The alignak.cfg allows to define what are the events that are logged to this file. By default, only the active and passive checks ran by Alignak are not logged to this file:

# Monitoring log configuration
# ---
# Note that alerts and downtimes are always logged
# ---
# Notifications
# log_notifications=1

# Services retries
# log_service_retries=1

# Hosts retries
# log_host_retries=1

# Event handlers
# log_event_handlers=1

# Flappings
# log_flappings=1

# Snapshots
# log_snapshots=1

# External commands
# log_external_commands=1

# Active checks
# log_active_checks=0

# Passive checks
# log_passive_checks=0

# Initial states
# log_initial_states=1

Configure Alignak notifications

As explained previously the alignak notifications pack needs to be configured for sending out the mail notifications. This demo configuration is using default parameters for the mail server that may be adapted to your own configuration.

With the default parameters, you will have some WARNING logs in the schedulerd.log file, such as:

[2017-01-07 10:00:47 CET] WARNING: [alignak.scheduler] The notification command '/usr/local/var/libexec/alignak/notify_by_email.py -t service -S localhost -ST 25 -SL your_smtp_login -SP your_smtp_password -fh -to guest@localhost -fr alignak@monitoring -nt PROBLEM -hn "alignak_glpi" -ha 127.0.0.1 -sn "Disk /var" -s CRITICAL -ls UNKNOWN -o "NRPE: Command 'check_var' not defined" -dt 0 -db "1483779644.85" -i 2  -p ""' raised an error (exit code=1): 'Traceback (most recent call last):'

To configure the Alignak mail notifications, edit the /usr/local/etc/alignak/arbiter/packs/resource.d/notifications.cfg file and set the proper parameters for your configuration:

#-- SMTP server configuration
$SMTP_SERVER$=localhost
$SMTP_PORT$=25
$SMTP_LOGIN$=your_smtp_login
$SMTP_PASSWORD$=your_smtp_password

# -- Mail configuration
$MAIL_FROM$=demo.server@alignak.net

You may also adapt the contacts used in this demo configuration else WE will receive you notification mails :). the used contacts are defined as is:

alignak.administrator@alignak.net, as the administrator contact for the realm All
north.administrator@alignak.net, as the administrator contact for the realm North
south.administrator@alignak.net, as the administrator contact for the realm South

You will find their definition in the /usr/local/etc/arbiter/realms folder, in each realm (All, North,…) contacts sub-folder.

Use Alignak Web services

The alignak Web Services module exposes some Web Services on the port 8888.

Get the Alignak daemons status:

http://127.0.0.1:8888/alignak_map

Note that the default configuration requires an HTTP authorized access with a basic HTTP authorization from a user existing in the alignak backend. You can disable this in the mod-ws.cfg file, else use curl with this syntax:

$ curl -H "Content-Type: application/json" -X GET -d '{"username":"admin","password":"admin"}' http://127.0.0.1:8888/alignak_map

For more information about the Alignak available services, please see the Alignak Web Services online documentation.

7. Configure/run Alignak Web UI

As of now, your configuration is monitored and you will receive notifications when something is detected as faulty. Everything is under control but why missing having an eye on what’s happening in your system with a more sexy interface than tailing a log file and reading emails?

Install the Alignak Web User Interface:

# Alignak WebUI
sudo pip install alignak-webui

The default installation is suitable for this demonstration but you may update the (/usr/local)/etc/alignak-webui/settings.cfg configuration file to adapt this default configuration.

Run the Alignak WebUI:

cd ~/demo
# Detach a screen session identified as "alignak-webui"
./alignak_webui_start.sh
# This will run the alignak-webui-uwsgi in a screen session. If you do not mind about a
# WebUI screen, you should run: alignak-webui-uwsgi

ps -aux | grep uwsgi
    root 26312  0.0  0.0  17096   2076 13  I+J  10:23AM 0:00.00 /bin/sh /usr/local/bin/alignak-webui-uwsgi
    root 26313  0.0  0.2 157324  38204 13  S+J  10:23AM 0:01.32 uwsgi --ini /usr/local/etc/alignak-webui/uwsgi.ini
    root 26318  0.0  0.4 178952  64724 13  S+J  10:23AM 0:20.76 uwsgi --ini /usr/local/etc/alignak-webui/uwsgi.ini
    root 26319  0.0  0.4 181512  68360 13  S+J  10:23AM 0:28.29 uwsgi --ini /usr/local/etc/alignak-webui/uwsgi.ini
    root 26320  0.0  0.5 203016  86876 13  S+J  10:23AM 1:00.70 uwsgi --ini /usr/local/etc/alignak-webui/uwsgi.ini
    root 26321  0.0  0.7 227336 111520 13  S+J  10:23AM 1:45.06 uwsgi --ini /usr/local/etc/alignak-webui/uwsgi.ini

# Joining the webui screen is 'screen -r alignak-webui'
# Ctrl+C in the screen will stop the WebUI
# kill -SIGTERM `cat /tmp/alignak-webui.pid`

# The alignak webui writes some logs as a Web server does
tail -f /usr/local/var/log/alignak-webui-error.log
tail -f /usr/local/var/log/alignak-webui-access.log

Use your Web browser to navigate to http://127.0.0.1:5001 and log in with admin / admin.

To use the WebUI from another machine (eg. if you are using a virtual machine), you can set a fake local loop:

ssh -L 5001:127.0.0.1:5001 login@ip_vm_test

The alignak WebUI runs thanks to uWSGI and its configuration is available in the /usr/local/alignak-webui/uwsgi.ini where you can define the log files location. You can also configure the Alignak WebUI to send its internal metrics to a Graphite timeseries database.

Note that a Grafana dashboard for the Alignak WebUI is available in the /usr/local/etc/alignak/sample/grafana directory created when you installed the alignak-demo package;)

8. Configure/run Alignak desktop applet

Except when you are in Big Brother mode, you almost always do not need a full Web interface as the one provided by the Alignak WebUI. This is why Alignak provides a desktop applet available for Linux and Windows desktops.

Install the Alignak App:

# For Linux users with python2
sudo apt-get install python-qt4
# For Linux and Windows users with python3
pip3 install PyQt5 --user

# For Windows users, we recommend using python3, else install PyQt from the download page.
# Otherwise, you can find a Windows installer on repository, with all packages inside, to run it.

# Alignak App
pip install alignak_app --user

# As of now, the last version is not yet pip installable, so we:
git clone https://github.com/Alignak-monitoring-contrib/alignak-app
cd alignak-app
pip install . --user

# Linux: Run the app (1st run)
$HOME/.local/alignak_app/alignak-app start
# Then you will be able for next runs to
alignak-app start

# Windows: Run the app
python "%APPDATA%\Python\alignak_app\bin\alignak-app.py
# If you used the Windows installer, just run the desktop shortcut "Alignak-app"

The applet will require a username and a password that are the same os the one used for the Web UI (use admin / admin). Click on the Alignak icon in the desktop toolbar to activate the Alignak-app features: alignak status, host synthesis view, host/services states, …

A notification popup will appear if something changed in the hosts / services states existing in the Alignak backend.

The default configuration is suitable for this demonstration but you may update the settings.cfg configuration file that is largely commented. On Linux, this file is located under $HOME/.local/alignak_app/ folder. On Windows, configuration file can be found under %APPDATA%Pythonalignak_app* or *%PROGRAMFILES%Alignak-app if you run installer.

9. Configure Alignak backend for timeseries

The Alignak backend allows to send collected performance data to a timeseries database. It must be configured to know where to send the timeseries data.

Note: Using StatsD as a front-end to the Graphite Carbon collector is not mandatory but it will help to have more regular statistics and it will maintain a metrics cache. But the purpose of this doc is not to discuss about the benefits / drawbacks of StatsD…

Using the Alignak WebUI makes it really easy to configure. Navigate to the Web UI Alignak backend menu and select the Backend Grafana item. Enter edition mode and add a new item. Also create a new Graphite item related to the Grafana item you just created, and that’s it …

You can also use command line scripts to create such information in the Alignak backend. Using the alignak-backend-client script makes it easy to configure this:

cd ~/demo

# Get the example configuration files
cp /usr/local/etc/alignak/sample/backend/* ~/demo

If you do not intend to use the StatsD daemon, execute these commands:

# Use Alignak backend CLI to add a Grafana instance
alignak-backend-cli -v add -t grafana --data=example_grafana.json grafana_demo

# Use Alignak backend to add a Graphite instance
alignak-backend-cli -v add -t graphite --data=example_graphite.json graphite_demo

If you do intend to use the StatsD daemon, execute these commands:

# Use Alignak backend CLI to add a Grafana instance
alignak-backend-cli -v add -t grafana --data=example_grafana.json grafana_demo

# Use Alignak backend CLI to add a StatsD instance
alignak-backend-cli -v add -t statsd --data=example_statsd.json statsd_demo

# Use Alignak backend to add a Graphite instance
alignak-backend-cli -v add -t graphite --data=example_graphite_statsd.json graphite_demo

You can edit the example_.json* provided files to include your own Graphite / Grafana (or InfluxDB) parameters. For more information see the Alignak backend documentation.

Warning: It will be mandatory to update the Grafana configuration with your own Grafana API key else the backend will not be able to create the Grafana dashboards and panels automatically!

Note: alignak-backend-cli is coming with the installation of the Alignak backend client.

10. Upgrading

Some updates are regularly pushed on the different alignak repositories and then you will sometime need to update this demo configuration. Before upgrading the application you should stop Alignak:

cd ~/demo
# Stop all alignak processes
./alignak_demo_stop.sh

# Check everything is stopped
ps -ef | grep alignak-

# Kill remaining processes. It may happen on a demo server;)
pkill alignak-broker

To upgrade Alignak, you can:

cd ~/repos/alignak

# Get the last develop version
git pull

# Install alignak and all its python dependencies
# -v will activate the verbose mode of pip
sudo pip install -v .

# Create alignak user/group and set correct permissions on installed configuration files
sudo ./dev/set_permissions.sh

To upgrade all the alignak packages that were installed, you can:

pip install -U pip list | grep alignak | awk '{ print $1}'

To list the currently installed packages and to know if they are up-to-date, you can use this command:

pip list --outdated | grep alignak

To get the list of outdated packages as a pip requirements list:

pip list --outdated --format columns | grep alignak | awk '{printf "%s==%s\n", $1, $3}' > alignak-update.txt

and to update:

pip install -r alignak-update.txt

What we see?

Monitored system status

The Alignak Web UI running on our demo server allows to view the monitored system status. Have a look here: http://demo.alignak.net. Several login may be used depending on the user role:

admin / admin, to get logged-in as an Administrator. You will see all the hosts and will be able to execute some commands (acknowledge a problem, schedule a downtime,…)
northman / north, to get logged-in as a power user in the North realm. You will see all the hosts of the All and North realms and will be able to execute commands.
southman / south, to get logged-in as a power user in the South realm. You will see all the hosts of the All and South realms and will be able to execute commands.

Alignak internal metrics

Alignak maintains its own internal metrics and it is able to send them to a StatsD server. Install the StatsD server locally (as explained later in this document) and update the alignak.cfg configuration file to enable this feature:

# Export all alignak inner performances into a statsd server.
# By default at localhost:8125 (UDP) with the alignak prefix
# Default is not enabled
statsd_host=localhost
#statsd_port=8125
statsd_prefix=alignak
statsd_enabled=1

We are running a demo Grafana server that allows to see the Alignak internal metrics. Several dashboards are available:

Alignak internal metrics shows the statistics provided by Alignak. This sample dashboard is available in the Alignak repository, contrib folder.
Graphite server reports on Carbon/Graphite own monitoring. This dashboard is available from the Grafana.net web site.

Installing StatsD / Graphite / Grafana

NOTE this section is a draft chapter. Currently the installatin described here is not fully functional !

StatsD

Install node.js on your server according to the recommended installation process.

On FreeBSD:

pkg install node

On Ubuntu / Debian:

# For Node.js 6
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs

To get the most recent StatsD (if you distro packaging do not provide it, you must clone the git repository:

$ cd ~
$ git clone https://github.com/etsy/statsd
$ cd statsd

# Create an alignak.js file with the following content (for a localhost Graphite)
$ cp exampleConfig.js alignak.js
$ cat alignak.js
{
      graphitePort: 2003
    , graphiteHost: "127.0.0.1"
    , port: 8125
    , backends: [ "./backends/graphite" ]

    /* Do not use any StatsD metric hierarchy */
    , graphite: {
        /* Do not use legacy namespace */
          legacyNamespace: false

        /* Set a global prefix */
        , globalPrefix: "alignak-statsd"

        /* Set empty prefixes */
        , prefixCounter: ""
        , prefixTimer: ""
        , prefixGauge: ""
        , prefixSet: ""

        /* Do not set any global suffix
        , globalSuffix: "_"
        */
    }
}


# Start the StatsD daemon in a screen
$ screen -S statsd
$ node stats.js alignak.js
# And leave the screen...
$ Ctrl+AD

# Test StatsD
$ ll /var/lib/graphite/whisper/alignak-statsd/statsd/
    total 84
    drwxr-xr-x 6 _graphite _graphite  4096 févr.  2 20:11 ./
    drwxr-xr-x 3 _graphite _graphite  4096 févr.  2 20:11 ../
    drwxr-xr-x 2 _graphite _graphite  4096 févr.  2 20:11 bad_lines_seen/
    drwxr-xr-x 2 _graphite _graphite  4096 févr.  2 20:11 graphiteStats/
    drwxr-xr-x 2 _graphite _graphite  4096 févr.  2 20:11 metrics_received/
    -rw-r--r-- 1 _graphite _graphite 17308 févr.  2 20:12 numStats.wsp
    drwxr-xr-x 2 _graphite _graphite  4096 févr.  2 20:11 packets_received/

    -rw-r--r-- 1 _graphite _graphite 17308 févr.  2 20:12 timestamp_lag.wsp

As of now you have a running StatsD daemon that will collect the Alignak internal metrics to feed Graphite.

Graphite Carbon

$ sudo su

$ apt-get update

# Set TZ as UTC
$ dpkg-reconfigure tzdata
=> UTC

# Install Carbon
$ apt-get install graphite-carbon

# Configure Carbon
$ vi /etc/default/graphite-carbon
# Enable carbon service on boot
=> CARBON_CACHE_ENABLED=true

# Configuration file
$ vi /etc/carbon/carbon.conf
# Enable log rotation
=> ENABLE_LOGROTATION = True

# Aggregation configuration (default is suitable...)
$ cp /usr/share/doc/graphite-carbon/examples/storage-aggregation.conf.example /etc/carbon/storage-aggregation.conf

# Start the metrics collector service (Carbon)
$ service carbon-cache start

# Monitor activity
$ tail -f /var/log/carbon/console.log

# Test carbon (send a metric test.count)
$ echo "test.count 4 `date +%s`" | nc -q0 127.0.0.1 2003
$ ls /var/lib/graphite/whisper
=> test/count.wsp

Graphite API

No need for the Graphite Web application, we will use Grafana ;)

$ sudo su

# Install Graphite-API
##### $ apt-get install graphite-api; do not seem to survive a system restart :)
$ wget https://github.com/brutasse/graphite-api/releases/download/1.1.2/graphite-api_1.1.2-1447943657-ubuntu14.04_amd64.deb
$ dpkg -i

# Install Nginx / uWsgi
$ apt-get install nginx uwsgi uwsgi-plugin-python

# Configure uWsgi
$ vi /etc/uwsgi/apps-available/graphite-api.ini
    [uwsgi]
    processes = 2
    socket = localhost:8080
    plugins = python27
    module = graphite_api.app:app
    buffer = 65536

$ ln -s /etc/uwsgi/apps-available/graphite-api.ini /etc/uwsgi/apps-enabled
$ service uwsgi restart

# Configure nginx
$ vi /etc/nginx/sites-available/graphite.conf
    server {
        listen 80;

        location / {
            include uwsgi_params;
            uwsgi_pass localhost:8080;
        }
    }

$ ln -s /etc/nginx/sites-available/graphite.conf /etc/nginx/sites-enabled
$ service nginx restart

StatsD

To be completed !

Grafana

# Install Grafana (Version 4 only supported by the Alignak backend!)
wget https://grafanarel.s3.amazonaws.com/builds/grafana_3.1.1-1470047149_amd64.deb
apt-get install -y adduser libfontconfig
dpkg -i grafana_3.1.1-1470047149_amd64.deb

# Configure Grafana (not necessary...)
$ vi /etc/grafana/grafana.ini

$ service grafana-server start

# Open your web browser on http://127.0.0.1:3000
