container collector

The container collector exposes metrics about containers running on a Hyper-V system

Metric name prefix	container
Data source	HCS, Kubernetes CRI
Enabled by default?	No

Flags

--collector.container.enabled

Comma-separated list of collectors to use. Defaults to all, if not specified. Available collectors: hcs, hostprocess.

• hcs collects containers managed by the Host Compute Service, for example Docker or process-isolated containerd containers.
• hostprocess collects Kubernetes HostProcess containers, which run in Win32 job objects instead of HCS.

--collector.container.cri-endpoint

Kubernetes Container Runtime Interface (CRI) endpoint. Defaults to npipe:////./pipe/containerd-containerd, the endpoint of containerd.

The collector reads the running containers and pod sandboxes from this endpoint to add the namespace, pod and container labels, to skip pause containers and to find HostProcess containers. If the endpoint is not available, for example on hosts without Kubernetes, the HCS containers are exported without Kubernetes labels and HostProcess containers aren't collected.

Metrics

windows_container_count	Number of running HCS containers	gauge	None
windows_container_cpu_usage_seconds_kernelmode	Runtime in Kernel mode in Seconds	counter	container_id,namespace,pod,container

windows_container_memory_usage_private_working_set_bytes	Memory Usage Private Working Set Bytes	gauge	container_id,namespace,pod,container
windows_container_network_receive_bytes_total	Bytes Received on Interface	counter	container_id,namespace,pod,container,interface
windows_container_network_receive_packets_total	Packets Received on Interface	counter	container_id,namespace,pod,container,interface
windows_container_network_receive_packets_dropped_total	Dropped Incoming Packets on Interface	counter	container_id,namespace,pod,container,interface

Example metric

windows_container_network_receive_bytes_total{container_id="docker://1bd30e8b8ac28cbd76a9b697b4d7bb9d760267b0733d1bc55c60024e98d1e43e",interface="822179E7-002C-4280-ABBA-28BCFE401826"} 9.3305343e+07

This metric means that total 9.3305343e+07 bytes received on interface 822179E7-002C-4280-ABBA-28BCFE401826 for container docker://1bd30e8b8ac28cbd76a9b697b4d7bb9d760267b0733d1bc55c60024e98d1e43e

Useful queries

Attach labels namespace/pod/container for Windows container metrics.

# kube_pod_container_info(a metric of kube-state-metrics) has labels namespace/pod/container/container_id for a container, while Windows container metrics only have container_id.
# Attaching labels namespace/pod/container for Windows container metrics, is useful to query for Windows pods.
windows_container_network_receive_bytes_total * on(container_id) group_left(namespace, pod, container) kube_pod_container_info{container_id!=""}

Alerting examples

This collector does not yet have alerting examples, we would appreciate your help adding them!
