****************************************

============
Build status
============
.. image:: https://travis-ci.org/postgrespro/mamonsu.svg?branch=master
    :target: https://travis-ci.org/postgrespro/mamonsu

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

============
Installation
============

Pre-Build packages for:

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

    `Windows installers <https://oc.postgrespro.ru/index.php/s/qu7YsFvOE55LdXo>`_

NOTE: pre-build packages on packagecloud only for mamonsu 2.3.4

Install via pip:

.. code-block:: bash

    $ pip install mamonsu

Install from git:

.. code-block:: bash

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

Build deb:

.. code-block:: bash

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

Build rpm:

.. code-block:: bash

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

Build win32 exe: (worked with python v3.{4,5}: py2exe v0.9.2.2 and pywin32 v220 or python v2.7: py2exe v0.6.9 and pywin32 v220):

.. code-block:: bash

    $ 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

NOTE: windows installer only for mamonsu 2.3.4 version

Build nsis installer:

.. code-block:: bash

    $ git clone ... && cd mamonsu && python setup_win32.py py2exe
    $ nsis packaging/win/mamonsu.nsis

==========
Configure
==========

Export template for zabbix:

.. code-block:: bash

    $ mamonsu export template template.xml --add-plugins /etc/mamonsu/plugins
    or
    $ cp /usr/share/mamonsu/template.xml .

or get example of config with all available parameters at https://postgrespro.ru/products/extensions/mamonsu

Import this file in web interface of zabbix: Configuration => Templates => Import, or deploy with mamonsu:

.. code-block:: bash

    $ mamonsu zabbix template export /usr/share/mamonsu/template.xml --url=http://zabbix/ --user=Admin --password=zabbix

Add this template like `PostgresPro-Linux2` at your monitoring host, or create host with mamonsu:

.. code-block:: bash

    $ mamonsu zabbix host create <client name> <hostgroup id> <template id> <ip> --url=http://zabbix/ --user=Admin --password=zabbix

Generate config on monitoring host or use preinstalled:

.. code-block:: bash

    $ mamonsu export config /etc/mamonsu/agent.conf --add-plugins /etc/mamonsu/plugins

or get example of config with all available parameters at https://postgrespro.ru/products/extensions/mamonsu

Change previously zabbix server address and client hostname:

.. code-block:: bash

    $ vim /etc/mamonsu/agent.conf

    $ cat /etc/mamonsu/agent.conf

    [zabbix]
    ; enabled by default
    enabled = True
    client = zabbix_client_host_name
    address = zabbix_server_ip

    [postgres]
    ; enabled by default
    enabled = True
    user = mamonsu
    database = mamonsu
    ; empty password
    password = None
    port = 5432
    query_timeout = 10

    [system]
    ; enabled by default
    enabled = True

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

These are the main mamonsu settings to get started. You can also fine-tune other mamonsu settings.
At https://postgrespro.ru/products/extensions/mamonsu you can find example of configuration file for mamonsu
with all available parameters.

Bootstrap DDL for monitoring (if you want to monitoring without superuser rights)

Create non-privileged user (for example 'mamonsu')

.. code-block:: bash

    $ createdb mamonsu

    $ createuser mamonsu

Implement bootstrap from non-privileged user

.. code-block:: bash

    $ mamonsu bootstrap -M mamonsu

==========================================================================
Work with zabbix-agent using template and configuration file from mamonsu
==========================================================================
NOTE: Mamonsu zabbix agent option does not work for Windows

Export template for zabbix-agent

.. code-block:: bash

    $ mamonsu export zabbix-template template_agent.xml

or get example of template at https://postgrespro.ru/products/extensions/mamonsu

Export or download zabbix-agent configuration file for needed PostgreSQL version

.. code-block:: bash

    $ mamonsu export zabbix-parameters userparameters_pgsql_v*.conf --pg-version=version_number (by default pg-version=10)

or get example of configuration file at https://postgrespro.ru/products/extensions/mamonsu

NOTE: zabbix-agent configuration file for PostgreSQL 10 and 11 are equal

Bash scripts for OS parameters monitoring are exported with configuration file in directory /scripts
Or you can download them  at https://postgrespro.ru/products/extensions/mamonsu

Add configuration file to zabbix-agent directory as /etc/zabbix/zabbix_agentd.d/userparameters_pgsql.conf

NOTE: Make sure path for bash scripts in zabbix-agent configuration file is valid

Edit connections options of zabbix-agent /etc/zabbix/zabbix_agentd.conf, following standard instructions for zabbix-agent installation (https://www.zabbix.com/documentation/3.4/manual/concepts/agent)

==================
Write your plugin
==================

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

See the `examples <https://github.com/postgrespro/mamonsu/tree/master/examples>`_ for aditional information.

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

=========
3rd-party
=========

* `repo mamonsu-plugins <https://github.com/tarabanton/mamonsu-plugins>`_ for skytools, nginx, rabbitmq, uwsgi, gdnsd.

====
Run
====

.. code-block:: bash

    $ service mamonsu start
    or by hand:
    $ mamonsu -d -a /etc/mamonsu/plugins -c /etc/mamonsu/agent.conf -p /var/run/mamonsu.pid
