This Check monitors the Container Runtime Containerd.
Containerd is a core Agent 6 check and thus needs to be configured in both in
datadog.yaml and with
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 env var to the daemonset mountPath:
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
/var/run directory must be mounted from the host to run the integration without issues.
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.
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.
The Containerd Check can collect events. Use
filters to select the relevant events. Refer to the sample containerd.d/conf.yaml to have more details.
CRITICAL if the Agent check is unable to connect to the monitored containerd socket. Returns
Statuses: ok, critical
