Containerd module

edit

This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

Containerd module collects cpu, memory and blkio statistics about running containers controlled by containerd runtime.

The current metricsets are: cpu, blkio and memory and are enabled by default.

Prerequisites

edit

Containerd daemon has to be configured to provide metrics before enabling containerd module.

In the configuration file located in /etc/containerd/config.toml metrics endpoint needs to be set and containerd daemon needs to be restarted.

[metrics]
    address = "127.0.0.1:1338"

Compatibility

edit

The Containerd module is tested with the following versions of Containerd: v1.5.2

Module-specific configuration notes

edit

For cpu metricset if calcpct.cpu setting is set to true, cpu usage percentages will be calculated and more specifically fields containerd.cpu.usage.total.pct, containerd.cpu.usage.kernel.pct, containerd.cpu.usage.user.pct. Default value is true.

For memory metricset if calcpct.memory setting is set to true, memory usage percentages will be calculated and more specifically fields containerd.memory.usage.pct and containerd.memory.workingset.pct. Default value is true.

Example configuration

The Containerd module supports the standard configuration options that are described in Modules. Here is an example configuration:

metricbeat.modules:
- module: containerd
  metricsets: ["cpu", "memory", "blkio"]
  period: 10s
  # containerd metrics endpoint is configured in /etc/containerd/config.toml
  # Metrics endpoint does not listen by default
  # https://github.com/containerd/containerd/blob/main/docs/man/containerd-config.toml.5.md
  hosts: ["localhost:1338"]
  # if set to true, cpu and memory usage percentages will be calculated. Default is true
  calcpct.cpu: true
  calcpct.memory: true
  #metrics_path: "v1/metrics"

Metricsets

The following metricsets are available:
