Cilium

Host

To configure this check for an Agent running on a host:

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

   • To collect cilium-agent metrics, enable the agent_endpoint option.
   • To collect cilium-operator metrics, enable the operator_endpoint option.

       instances:
   
           ## @param use_openmetrics - boolean - optional - default: false
           ## Use the latest OpenMetrics implementation for more features and better performance.
           ##
           ## Note: To see the configuration options for the legacy OpenMetrics implementation (Agent 7.33 or older),
           ## see https://github.com/DataDog/integrations-core/blob/7.33.x/cilium/datadog_checks/cilium/data/conf.yaml.example
           #
         - use_openmetrics: true # Enables OpenMetrics latest mode
   
           ## @param agent_endpoint - string - optional
           ## The URL where your application metrics are exposed by Prometheus.
           ## By default, the Cilium integration collects `cilium-agent` metrics.
           ## One of agent_endpoint or operator_endpoint must be provided.
           #
           agent_endpoint: http://localhost:9090/metrics
   
           ## @param operator_endpoint - string - optional
           ## Provide instead of `agent_endpoint` to collect `cilium-operator` metrics.
           ## Cilium operator metrics are exposed on port 6942.
           #
           operator_endpoint: http://localhost:6942/metrics
   

2. Restart the Agent .

Log collection

Cilium contains two types of logs: cilium-agent and cilium-operator.

1. Collecting logs is disabled by default in the Datadog Agent. Enable it in your DaemonSet configuration :

     # (...)
       env:
       #  (...)
         - name: DD_LOGS_ENABLED
             value: "true"
         - name: DD_LOGS_CONFIG_CONTAINER_COLLECT_ALL
             value: "true"
     # (...)
   

2. Mount the Docker socket to the Datadog Agent through the manifest or mount the /var/log/pods directory if you are not using Docker. For example manifests see the Kubernetes Installation instructions for DaemonSet .

3. Restart the Agent .

Containerized

For containerized environments, see the Autodiscovery Integration Templates for guidance on applying the parameters below.

Collecting logs is disabled by default in the Datadog Agent. To enable it, see Kubernetes Log Collection .

To collect cilium-agent metrics and logs:
