-## Overview
-
-This collector monitors the state of Systemd units and unit files.
-
-
-
-
-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 |
-
-### Per unit file
-
-These metrics refer to the systemd unit file.
-
-Labels:
-
-| Label      | Description     |
-|:-----------|:----------------|
-| unit_file_name | systemd unit file name |
-| unit_file_type | systemd unit file type |
-
-Metrics:
-
-| Metric | Dimensions | Unit |
-|:------|:----------|:----|
-| systemd.unit_file_state | enabled, enabled-runtime, linked, linked-runtime, alias, masked, masked-runtime, static, disabled, indirect, generated, transient, bad | state |
