Ansible role for Node exporter

This role will setup Node exporter on any Linux machine using systemd.

Role Variables

• node_exporter_version: the version of Node exporter that will be installed.

The role will download the Node exporter release on the deployer and upload the binary to the target host.

If the /usr/local/bin/node_exporter binary already exists, the role will skip the install steps. You can force them (to update, for instance), by setting node_exporter_force_install to true.

• node_exporter_system_group: the name of the group that will run Node exporter.(node-exporter)
• node_exporter_system_user: the name of the user that will run Node exporter. Default to node_exporter_system_group.
• node_exporter_web_listen_address: the address Node exporter will listen on. (0.0.0.0:9100)

Node exporter comes with a default set of enabled and disabled collectors.

You can enable more collectors with node_exporter_enabled_collectors.

The default is:

node_exporter_enabled_collectors:
  - systemd
  - ntp
  - filesystem:
      ignored-mount-points: "^/(sys|proc|dev)($|/)"
      ignored-fs-types: "^(sys|proc|auto)fs$"

To disable collectors, use node_exporter_enabled_collectors. It's empty by default.
