dj-wasabi.zabbix-agent

This is an role for installing and maintaining the zabbix-agent.

This is one of the 'dj-wasabi' roles which configures your whole zabbix environment. See an list for the complete list:

zabbix-server (https://galaxy.ansible.com/list#/roles/2070)
zabbix-proxy (https://galaxy.ansible.com/list#/roles/2073)
zabbix-javagateway (https://galaxy.ansible.com/list#/roles/2076)
zabbix-agent (https://galaxy.ansible.com/list#/roles/2079)

Requirements

This role will work on:

Red Hat
Debian
Ubuntu
opensuse

So, you'll need one of those operating systems.. :-)

When you want to automatically create the hosts in the webinterface, you'll need on your own machine the zabbix-api package. You can install this locally with the following command: pip install zabbix-api. This ansible role uses the modules from "Cove" found in this pull request: ansible/ansible-modules-extras#44. So all credits goes to this guy!

Role Variables

There are some variables in de default/main.yml which can (Or needs to) be changed/overriden:

agent_server: The ipaddress for the zabbix-server or zabbix-proxy.
agent_serveractive: The ipaddress for the zabbix-server or zabbix-proxy for active checks.
zabbix_version: This is the version of zabbix. Default it is 2.4, but can be overriden to 2.2 or 2.0.
zabbix_repo: When you already have an repository with the zabbix components, you can set it to False.
agent_listeninterface: On which interface zabbix-agent is listening. Default: eth0

These variables needs to be changed/overriden when you want to make use of the zabbix-api for automatically creating and or updating hosts.

zabbix_url: The url on which the Zabbix webpage is available. Example: http://zabbix.example.com
zabbix_api_use: When you want to make use of the Zabbix-API. Default: False
zabbix_api_user: Username of user which has API access.
zabbix_api_pass: Password for the user which has API access.
zabbix_create_hostgroup: present (Default) if you want to create hostgroups or absent if you not.
zabbix_host_status: enabled (Default) when host in monitored, disabled when host is disabled for monitoring.
zabbix_create_host: present # or absent
zabbix_useuip: 1 if connection to zabbix-agent is made via ip, 0 for fqdn.
zabbix_host_groups: An list of hostgroups which this host belongs to.
zabbix_link_templates: An list of templates which needs to be link to this host. The templates should exist.
zabbix_macros: An list with macro_key and macro_value for creating hostmacro's.

Dependencies

There are no dependencies on other roles.

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: all
  roles:
     - role: dj-wasabi.zabbix-agent
       agent_server: 192.168.33.30
       agent_serveractive: 192.168.33.30
       zabbix_url: http://zabbix.example.com
       zabbix_api_use: true
       zabbix_api_user: Admin
       zabbix_api_pass: zabbix
       zabbix_create_host: present
       zabbix_host_groups:
         - Linux Servers
       zabbix_link_templates:
         - Template OS Linux
         - Apache APP Template
       zabbix_macros:
         - macro_key: apache_type
           macro_value: reverse_proxy

You can also use the group_vars or host_vars for setting some vars.

	cat group_vars/all
	agent_server: 192.168.33.30
    agent_serveractive: 192.168.33.30
    zabbix_url: http://zabbix.example.com
    zabbix_api_use: true
    zabbix_api_user: Admin
    zabbix_api_pass: zabbix
    zabbix_create_host: present
    zabbix_host_groups:
      - Linux Servers
    zabbix_link_templates:
      - Template OS Linux
      - Apache APP Template
    zabbix_macros:
      - macro_key: apache_type
        macro_value: reverse_proxy

and in the playbook only specifying:

- hosts: all
  roles:
     - role: dj-wasabi.zabbix-agent

Extra Information

You can install so-called userparameter files by adding the following into your roles:

- name: "Installing sample file"
  copy: src=sample.conf
        dest="{{ agent_include }}/mysql.conf"
        owner=zabbix
        group=zabbix
        mode=0755
  notify: "{{ zabbix_agent }} restarted"

Example of the "sample.conf" file:

UserParameter=mysql.ping_to,mysqladmin -uroot ping | grep -c alive

You can extend your zabbix configuration by adding items yourself that do specific checks which aren't in the zabbix core itself. You can change offcourse the name of the file to whatever you want (Same for the UserParameter line(s) ;-) )
