Systemd Services

Plugin: cgroups.plugin Module: /sys/fs/cgroup

Overview

Monitor systemd service resource utilization — CPU, memory, and disk I/O — via Linux cgroups.

This collector is only supported on the following platforms:

• Linux

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

Options

There are no configuration options.

via File

There is no configuration file.

Examples

There are no configuration examples.

Alerts

There are no alerts configured by default for this integration.

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 systemd service

Labels:

Label	Description
service_name	Service name
