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 |
mysqld_exporter_web_listen_address |
"0.0.0.0:9104" | Address on which mysqld exporter will listen |
Example
Playbook
Use it in a playbook as follows:
- hosts: all
become: yes
roles:
- cloudalchemy.mysqld_exporterDemo 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.
