Systemd Units

Plugin: go.d.plugin Module: systemdunits

Overview

This collector monitors Systemd units state.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

Default Behavior

Auto-Detection

This integration doesn't support auto-detection.

Limits

The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.

Metrics

Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per unit

These metrics refer to the systemd unit.

Labels:

Label	Description
unit_name	systemd unit name

Metrics:

Metric	Dimensions	Unit
systemd.service_unit_state	active, inactive, activating, deactivating, failed	state
systemd.socket_unit_state	active, inactive, activating, deactivating, failed	state
systemd.target_unit_state	active, inactive, activating, deactivating, failed	state
systemd.path_unit_state	active, inactive, activating, deactivating, failed	state
systemd.device_unit_state	active, inactive, activating, deactivating, failed	state
systemd.mount_unit_state	active, inactive, activating, deactivating, failed	state
systemd.automount_unit_state	active, inactive, activating, deactivating, failed	state
systemd.swap_unit_state	active, inactive, activating, deactivating, failed	state
systemd.timer_unit_state	active, inactive, activating, deactivating, failed	state
systemd.scope_unit_state	active, inactive, activating, deactivating, failed	state
systemd.slice_unit_state	active, inactive, activating, deactivating, failed	state

The following alerts are available:

Alert name	On metric	Description
systemd_service_unit_failed_state	systemd.service_unit_state	systemd service unit in the failed state
systemd_socket_unit_failed_state	systemd.socket_unit_state	systemd socket unit in the failed state
systemd_target_unit_failed_state	systemd.target_unit_state	systemd target unit in the failed state
systemd_path_unit_failed_state	systemd.path_unit_state	systemd path unit in the failed state
systemd_device_unit_failed_state	systemd.device_unit_state	systemd device unit in the failed state
systemd_mount_unit_failed_state	systemd.mount_unit_state	systemd mount unit in the failed state
systemd_automount_unit_failed_state	systemd.automount_unit_state	systemd automount unit in the failed state
systemd_swap_unit_failed_state	systemd.swap_unit_state	systemd swap unit in the failed state
systemd_scope_unit_failed_state	systemd.scope_unit_state	systemd scope unit in the failed state
systemd_slice_unit_failed_state	systemd.slice_unit_state	systemd slice unit in the failed state

Setup

Prerequisites

No action required.

Configuration

File

The configuration file name for this integration is go.d/systemdunits.conf.

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/systemdunits.conf

Options

The following options can be defined globally: update_every, autodetection_retry.

Config options

Name	Description	Default	Required
update_every	Data collection frequency.		False
autodetection_retry	Recheck interval in seconds. Zero means no recheck will be scheduled.		False
include	Systemd units filter.		False
timeout	System bus requests timeout.		False

include

Systemd units matching the selector will be monitored.

• Logic: (pattern1 OR pattern2)
• Pattern syntax: shell file name pattern
• Syntax:

includes:
  - pattern1
  - pattern2

Examples

Service units

Collect state of all service type units.

Config

jobs:
  - name: service
    include:
      - '*.service'

One specific unit

Collect state of one specific unit.

Config

jobs:
  - name: my-specific-service
    include:
      - 'my-specific.service'

All unit types

Collect state of all units.

Config

jobs:
  - name: my-specific-service-unit
    include:
      - '*'

Multi-instance

Note: When you define multiple jobs, their names must be unique.

Collect state of all service and socket type units.

Config

jobs:
  - name: service
    include:
      - '*.service'

  - name: socket
    include:
      - '*.socket'

Troubleshooting

Debug Mode

To troubleshoot issues with the systemdunits collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

• Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].

  cd /usr/libexec/netdata/plugins.d/

• Switch to the netdata user.

  sudo -u netdata -s

• Run the go.d.plugin to debug the collector:

  ./go.d.plugin -d -m systemdunits
