Build status

License

Development version, available on github, released under BSD 3-clause.

Installation

Pre-Build packages for:

Linux distros: https://packagecloud.io/postgrespro/mamonsu

Windows installers

Install via pip:

$ pip install mamonsu

Install from git:

$ git clone ... && cd mamonsu && python setup.py build && python setup.py install

Build deb:

$ apt-get install make dpkg-dev debhelper python-dev python-setuptools
$ git clone ... && cd mamonsu && make deb && dpkg -i mamonsu*.deb

Build rpm:

$ yum install make rpm-build python2-devel python-setuptools
$ git clone ... && cd mamonsu && make rpm && rpm -i mamonsu*.rpm

Build exe (worked with python v3.4, py2exe v0.9.2.2, pywin32 v220):

If you have error with ctypes: try to extend bootstrap_modules (add “ctypes”) in Libsite-packagespy2exeruntime.py

$ git clone ... && cd mamonsu && python setup_win32.py py2exe
$ cp dist\{mamonsu, service_win32}.exe c:\mamonsu
$ c:\mamonsu\mamonsu.exe -w c:\mamonsu\agent.conf
$ c:\mamonsu\service_win32.exe -install
$ net start mamonsu

Configure

Export template for zabbix:

$ mamonsu -e template.xml

Import this file in web interface of zabbix: Configuration => Templates => Import.

Add this template like PostgresPro-Linux at your monitoring host.

Generate config on monitring host:

$ mamonsu -w /etc/mamonsu/agent.conf

Change previously zabbix server address and client hostname:

$ vim /etc/mamonsu/agent.conf

$ cat /etc/mamonsu/agent.conf

[zabbix]
client = zabbix_client_host_name
address = zabbix_server_ip

[postgres]
user = postgres
database = postgres
; empty password
password = None
port = 5432
query_timeout = 10

[plugins]
; directory with user plugins
directory = /etc/mamonsu/plugins

[log]
file = /var/log/mamonsu/agent.log
level = INFO

Write your plugin

All plugins must exist in plugin directory which is defined in your configuration file.

See the examples for aditional information.

After add new plugin, you must to reexport template and import this file to zabbix.

Run

$ service mamonsu status
or by hand:
$ mamonsu -c /etc/mamonsu/agent.conf -p /var/run/mamonsu.pid

Report tool

$ mamonsu report --help

Auto tune PostgreSQL

$ mamonsu tune --help
