This check monitors the Containerd container runtime.

Containerd is a core Datadog Agent check. You must configure Containerd in both datadog.yaml and containerd.d/conf.yaml.

In datadog.yaml, configure your cri_socket_path for the Agent to query Containerd. In containerd.d/conf.yaml, configure the check instance settings (such as filters) for the events.

If you are using the Agent in a container, setting the DD_CRI_SOCKET_PATH environment variable to the Containerd socket automatically enables the Containerd integration with the default configuration.

For example, to install the integration on Kubernetes, edit your DaemonSet to mount the Containerd socket from the host node to the Agent container and set the DD_CRI_SOCKET_PATH environment variable to the DaemonSet mount path:

apiVersion: extensions/v1beta1
kind: DaemonSet
metadata:
  name: datadog-agent
spec:
  template:
    spec:
      containers:
        - name: datadog-agent
          # ...
          env:
            - name: DD_CRI_SOCKET_PATH
              value: /var/run/containerd/containerd.sock
          volumeMounts:
            - name: containerdsocket
              mountPath: /var/run/containerd/containerd.sock
            - mountPath: /host/var/run
              name: var-run
              readOnly: true
          volumes:
            - hostPath:
                path: /var/run/containerd/containerd.sock
              name: containerdsocket
            - hostPath:
                path: /var/run
              name: var-run

Note: The /var/run directory must be mounted from the host to run the integration without issues.

apiVersion: extensions/v1beta1
kind: DaemonSet

  name: datadog-agent
spec:
  template:
    spec:
      containers:
        - name: datadog-agent
          # ...
          env:
            - name: DD_CRI_SOCKET_PATH
              value: \\\\.\\pipe\\containerd-containerd
          volumes:
            - hostPath:
                path: \\\\.\\pipe\\containerd-containerd
              name: containerdsocket
          volumeMounts:
            - name: containerdsocket
              mountPath: \\\\.\\pipe\\containerd-containerd

1. Edit the containerd.d/conf.yaml file, in the conf.d/ folder at the root of your Agent's configuration directory to start collecting your Containerd performance data. See the sample containerd.d/conf.yaml for all available configuration options.

2. Restart the Agent

Run the Agent's status subcommand and look for containerd under the Checks section.

Containerd collects metrics about the resource usage of your containers.

CPU, memory, block I/O, or huge page table metrics are collected out of the box. Additionally, you can also collect some disk metrics.

See metadata.csv for a list of metrics provided by this integration.

This integration works on Linux and Windows, but some metrics are OS dependent. Look at metadata.csv for the list of OS dependent metrics.

The Containerd check can collect events. Use filters to select the relevant events. See the sample containerd.d/conf.yaml to have more details.

See service_checks.json for a list of service checks provided by this integration.
