Ansible Role: mysqld exporter

Description

Deploy prometheus mysqld exporter using ansible.

Requirements

Ansible >= 2.7 (It might work on previous versions, but we cannot guarantee it)

Role Variables

All variables which can be overridden are stored in defaults/main.yml file as well as in table below.

Name	Default Value	Description
`mysqld_exporter_version`	0.12.1	mysqld exporter package version. Versions before 0.11 aren't supported.
`mysqld_exporter_binary_local_dir`	""	Allows to use local packages instead of ones distributed on github. As parameter it takes a directory where `mysqld_exporter` binary is stored on host on which ansible is ran. This overrides `mysqld_exporter_version` parameter

Example

Playbook

Use it in a playbook as follows:

- hosts: all
  become: yes
  roles:
    - cloudalchemy.mysqld_exporter

Demo site

We provide demo site for full monitoring solution based on prometheus and grafana. Repository with code and links to running instances is available on github and site is hosted on DigitalOcean.

Local Testing

The preferred way of locally testing the role is to use Docker and molecule (v3.x). You will have to install Docker on your system. See "Get started" for a Docker package suitable to for your system. Running your tests is as simple as executing molecule test.

Continuous Intergation

Combining molecule and circle CI allows us to test how new PRs will behave when used with multiple ansible versions and multiple operating systems. This also allows use to create test scenarios for different role configurations. As a result we have a quite large test matrix which can take more time than local testing, so please be patient.
