Recommendations

Recommended settings for monitoring and collecting metrics for Kubernetes, platform services, and applications deployed on the cluster

D2iQ conducts routine performance testing of Kommander. The following table provides recommended settings, based on cluster size and increasing workloads, that maintain a healthy Prometheus monitoring deployment.

NOTE: The resource settings reflect some settings but do not represent the exact structure to be used in the platform service configuration.
