Kubernetes integration release notesRSS

Notes

Follow standard procedures to install or update the New Relic integration for Kubernetes.

Changelog

Added: Node labels are now retrieved from the Kubernetes API and added to the K8sNodeSample. They can now be selected in the Narrow Down Entities section of the infrastructure alerts page to filter entities when using the K8sNodeSample, and can also be used on any NRQL statement when querying the K8sNodeSample. Ex:

FROM K8sNodeSample SELECT average(cpuUsedCoreMilliseconds) WHERE `label.kubernetes.io/role` = 'master'

By default, Information retrieved from the Kubernetes API is cached for 5 minutes. The cache time can be changed with the API_SERVER_CACHE_TTL environment variable.

Changed: The integration now uses the Infrastructure Agent v1.5.51. For more information, please refer to the infrastructure agent release notes between versions v1.5.31 and v1.5.51.

Changelog

Added: Support for kube-state-metrics (KSM) 1.5.

Added: The reason and message attributes are added to K8sPodSample. This will provide visibility into why a pod status is Failed.

For example, a pod that failed due to memory pressure on the node will report the following attributes:

• Status: Failed
• Reason: Evicted
• Message: Pod The node was low on resource: [MemoryPressure]

It is possible to create an alert for any of these attributes.

Added: The memoryWorkingSetBytes attribute is added to K8sContainerSample. This metric is used by the OOMkiller to decide when a container is using too much memory compared to its limit and should therefore be killed. It will enable more precise monitoring of the memory usage for containers.

Changed: Always request metrics from kube-state-metrics in text format. In KSM's v1.5 this is the default regardless of the format requested.
