cAdvisor 🔗

Description 🔗

This receiver pulls metrics directly from cAdvisor, which runs by default on port 4194, but can be configured to any other port.

If you are using Kubernetes, consider the Kubelet Stats receiver because many Kubernetes nodes do not expose cAdvisor on a network port, even though they are running it within Kubelet.

If you are running containers using Docker and the Docker Containers receiver, metrics duplication might happen, with the same metric data sent under different metric names. Consider not enabling the Docker Containers receiver in a Kubernetes environment, or use filtering to allow only certain metrics. Deactivating the Docker Containers receiver causes the built-in Docker dashboards to be empty, though container metrics are available on the Kubernetes dashboards instead.

Benefits 🔗

After you configure the integration, you can access these features:

View metrics. You can create your own custom dashboards, and most monitors provide built-in dashboards as well. For information about dashboards, see View dashboards in Observability Cloud.
View a data-driven visualization of the physical servers, virtual machines, AWS instances, and other resources in your environment that are visible to Infrastructure Monitoring. For information about navigators, see Splunk Infrastructure Monitoring navigators.
Access the Metric Finder and search for metrics sent by the monitor. For information, see Use the Metric Finder.

Installation 🔗

Follow these steps to deploy this integration:
