Deploy prometheus node exporter using ansible.
- Ansible >= 2.3
All variables which can be overridden are stored in defaults/main.yml file as well as in table below.
Name | Default Value | Description |
---|---|---|
node_exporter_version |
0.15.2 | Node exporter package version |
node_exporter_web_listen_address |
"0.0.0.0:9100" | Address on which node exporter will listen |
node_exporter_enabled_collectors |
[ conntrack, diskstats, entropy, filefd, filesystem, hwmon, loadavg, mdadm, meminfo, netdev, netstat, stat, textfile, time, vmstat, systemd, ntp ] | List of enabled collectors |
node_exporter_disabled_collectors |
[ logind ] | List of disabled collectors |
Use it in a playbook as follows:
- hosts: all
become: yes
roles:
- cloudalchemy.node-exporter
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.
The preferred way of locally testing the role is to use Docker and molecule (v2.x). You will have to install Docker on your system. See Get started for a Docker package suitable to for your system. All packages you need to can be specified in one line:
pip install ansible 'ansible-lint>=3.4.15' 'molecule>2.13.0' docker 'testinfra>=1.7.0' jmespath
This should be similar to one listed in .travis.yml
file in install
section.
After installing test suit you can run test by running
molecule test --all
For more information about molecule go to their docs.
Combining molecule and travis 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 (42 parallel role executions in case of ansible-prometheus) which will take more time than local testing, so please be patient.
