Systemd Units
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.
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.
| Name | Description | Default | Required |
|---|---|---|---|
| update_every | Data collection frequency. | 1 | False |
| autodetection_retry | Recheck interval in seconds. Zero means no recheck will be scheduled. | 0 | False |
| include | Systemd units filter. | *.service | False |
| timeout | System bus requests timeout. | 1 | False |
include
Systemd units matching the selector will be monitored.

Examples
Service units
Collect state of all service type units.
jobs:
- name: service
include:
- '*.service'
One specific unit
Collect state of one specific unit.
jobs:
- name: my-specific-service
include:
- 'my-specific.service'
All unit types
Collect state of all units.
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.
jobs:
- name: service
include:
- '*.service'
- name: socket
include:
- '*.socket'
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 |

| 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 |
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.ddirectory, usually at/usr/libexec/netdata/plugins.d/. If that’s not the case on your system, opennetdata.confand look for thepluginssetting under[directories].cd /usr/libexec/netdata/plugins.d/ -
Switch to the
netdatauser.sudo -u netdata -s -
Run the
go.d.pluginto debug the collector:./go.d.plugin -d -m systemdunits
