zabbix-formula

A saltstack formula to manage Zabbix.

This formula has been developed distributing declarations in different files to make it usable in most situations. It should be useful in scenarios ranging from a simple install of the packages (without any special configuration) to a more complex set-up with different nodes for agent, server, database and frontend.

General customization strategies

• Use pillar data. This is the absolutely recommended way to use the formula. In most occassions all you need is to fill some of the key-values shown in the pillar.example file. If you feel that a certain value should be there then don't hesitate to propose an enhancement.
• Use the extra_conf key that in some cases is present in the pillar to add arbitrary configuration lines in the templates provided. This is a way to have a better customization without over-populating the pillar with new key-values.

• Add new subdirectories under files in addition to default. This new subdirectories will contain different files to be used in certain conditions. This selection mechanism is based by default in the ìd grain of the minion (i.e. if there's a new subdirectory named minion01 then the formula is going to look there first for that minion). This selection behavior can be extended to make it depend on any sorted list of grains, defined by the key files_switch.

  For example, let's define in pillar something like:

  formula-name:
    files_switch: ['id', 'os_family']

  Let's have this files directory structure:

  files
    |-- minion01
    |       `-- etc
    |            `-- foo.conf.jinja
    |-- Debian
    |       `-- etc
    |            `-- foo.conf.jinja
    `-- default
            |-- etc
            |    |-- foo.conf.jinja
            |    `-- bar.conf.jinja
            `-- usr/share/thingy/*

  With this, we have the following:

  • if the minion id is minion01 then files/minion01/etc/foo.conf.jinja is going to be used
  • else if the minion os_family is Debian then files/Debian/etc/foo.conf.jinja is going to be used
  • else files/default/etc/foo.conf.jinja is going to be used

  Beware: this is not designed to substitute pillar data. Remember that pillar has to be used for information that it's essential to be only known for a certain set of minions (i.e. passwords, private keys and such).

• As a last resort you can actually fork the formula to suit your needs, keeping an eye for further improvements to merge into yours. Of course any pull-request that you can bring back it would be taken in account ;-)

Using RedHat EPEL repo Zabbix packages

If you want to use the EPEL repo packages, as the naming conventions are different, you need to tweak the default values of map.jinja to obtain the desired results. In short:

• Don't use the zabbix.agent.repo sls assuming that EPEL repos are already configured
• Override the map.jinja definitions using pillar values like this

zabbix:
  lookup:
    agent:
      pkg: zabbix22-agent
    server:
      pkg: zabbix22-server-mysql

Now you just have to use zabbix.agent.conf sls file and that's it.

Example of usage

Just as an example, this is a top.sls file to install a complete modular self- contained Zabbix system:

base:
  'minion':
    - zabbix.agent.repo
    - zabbix.agent.conf
    - mysql.server
    - mysql.client
    - zabbix.mysql.conf
    - zabbix.mysql.schema
    - zabbix.server.repo
    - zabbix.server.conf
    - apache.repo
    - apache.conf
    - apache.users
    - apache.mod_proxy_fcgi
    - apache.mod_actions
    - php5.fpm.repo
    - php5.fpm.conf
    - php5.mysql
    - zabbix.frontend.repo
    - zabbix.frontend.conf

You need the appropriate apache and php5 formulas to complete the frontend installation.

Note

See the full Salt Formulas doc.

Available states

zabbix.repo

Configures official Zabbix repo.

zabbix.users

Declares users and groups that could be needed in other formulas (e.g. in the users formula to make an user pertain to the service group).

zabbix.agent

Installs the zabbix-agent package and starts the associated zabbix-agent service.

zabbix.agent.conf

Configures the zabbix-agent package.

zabbix.agent.repo

Configures official Zabbix repo specifically for the agent. Actually just include zabbix.repo and adds arequisite for the pkg state declaration

zabbix.server

Installs the zabbix-server package and starts the associated zabbix-server service.

zabbix.server.conf

Configures the zabbix-server package.

zabbix.server.repo

Configures official Zabbix repo specifically for the server. Actually just include zabbix.repo and adds arequisite for the pkg state declaration

zabbix.mysql

Creates database and mysql user for Zabbix.

zabbix.mysql.conf

Creates mysql schema for Zabbix.

zabbix.frontend

Installs Zabbix frontend.

zabbix.frontend.repo ----------------------

Configures official Zabbix repo specifically for the frontend. Actually just include zabbix.repo and adds arequisite for the pkg state declaration.

zabbix.frontend.conf ----------------------

Configures the zabbix-frontend package. Actually you need to use other formulas for apache/nginx and php5-fpm to complete a working setup.
