alerta-server 6.0.0

Alerta server WSGI application

Alerta Release 6.0
==================

[](https://travis-ci.org/alerta/alerta)
[](https://gitter.im/alerta/chat)

The Alerta monitoring tool was developed with the following aims in mind:

* distributed and de-coupled so that it is **SCALABLE**
* minimal **CONFIGURATION** that easily accepts alerts from any source
* quick at-a-glance **VISUALISATION** with drill-down to detail

Python 2.7 support is EOL
-------------------------

Starting with Release 6.0 only Python 3.5+ is supported. Release 5.2 was the
last to support Python 2.7 and feature enhancements for this release ended on
August 31, 2018. Only critical bug fixes will be backported to Release 5.2.

Requirements
------------

The only mandatory dependency is MongoDB or PostgreSQL. Everything else is optional.

- Postgres version 9.5 or better
- MongoDB version 3.x

Installation
------------

To install MongoDB on Debian/Ubuntu run::

$ sudo apt-get install -y mongodb-org
$ mongod

To install the Alerta server and client run::

$ pip install alerta-server alerta
$ alertad run

To install the web console run::

$ wget -O alerta-web.tgz https://github.com/alerta/angular-alerta-webui/tarball/master
$ tar zxvf alerta-web.tgz
$ cd alerta-angular-alerta-webui-*/app
$ python -m http.server 8000

>> browse to http://localhost:8000

Configuration
-------------

To configure the ``alertad`` server override the default settings in ``/etc/alertad.conf``
or using ``ALERTA_SVR_CONF_FILE`` environment variable::

$ ALERTA_SVR_CONF_FILE=~/.alertad.conf
$ echo "DEBUG=True" > $ALERTA_SVR_CONF_FILE

Documentation
-------------

More information on configuration and other aspects of alerta can be found
at <http://docs.alerta.io>

Development
-----------

To run in development mode, listening on port 5000::

$ export FLASK_APP=alerta FLASK_ENV=development
$ pip install -e .
$ flask run

To run in development mode, listening on port 8080, using Postgres and
reporting errors to [Sentry](https://sentry.io)::

$ export FLASK_APP=alerta FLASK_ENV=development
$ export DATABASE_URL=postgres://localhost:5432/alerta5
$ export SENTRY_DSN=https://8b56098250544fb78b9578d8af2a7e13:[e-mail]/153768
$ pip install -e .
$ flask run --debugger --port 8080 --with-threads --reload

Troubleshooting
---------------

Problems following a direct upgrade from versions 4.x to 5.x could be
related to the flattening of the directory structure for the app. An
example `app.wsgi` file which works for both release 4 and 5 is as
follows:

```
#!/usr/bin/env python

try:
from alerta import app # alerta >= 5.0
except Exception:
from alerta.app import app # alerta < 5.0
```

Tests
-----

To run the tests using a local Postgres database run::

$ pip install -r requirements.txt
$ pip install -e .
$ createdb test5
$ ALERTA_SVR_CONF_FILE= DATABASE_URL=postgres:///test5 nosetests

Cloud Deployment
----------------

Alerta can be deployed to the cloud easily using Heroku <https://github.com/alerta/heroku-api-alerta>,
AWS EC2 <https://github.com/alerta/alerta-cloudformation>, or Google Cloud Platform
<https://github.com/alerta/gcloud-api-alerta>
