systemd_units

systemd Units Input Plugin

The systemd_units plugin gathers systemd unit status on Linux. It relies on systemctl list-units --all --plain --type=service to collect data on service status.

The results are tagged with the unit name and provide enumerated fields for loaded, active and running fields, indicating the unit health.

This plugin is related to the win_services module, which fulfills the same purpose on windows.

In addition to services, this plugin can gather other unit types as well, see systemctl list-units --all --type help for possible options.

Configuration

[[inputs.systemd_units]]
  ## Set timeout for systemctl execution
  # timeout = "1s"
  #
  ## Filter for a specific unit type, default is "service", other possible
  ## values are "socket", "target", "device", "mount", "automount", "swap",
  ## "timer", "path", "slice" and "scope ":
  # unittype = "service"

Metrics

  • systemd_units:
    • tags:
      • name (string, unit name)
      • load (string, load state)
      • active (string, active state)
      • sub (string, sub state)
    • fields:
      • load_code (int, see below)
      • active_code (int, see below)
      • sub_code (int, see below)
