  • Red Hat Enterprise Linux 7 and 8
  • CentOS 7

Prometheus histogram metrics

Prometheus histogram metrics are now ingested by default.

  • The _sum and _count parts of the histogram are ingested as dedicated counter metrics.

For example, the istio_request_duration_milliseconds histogram metric results in two counter metrics:

  • istio_request_duration_milliseconds_sum.count
  • istio_request_duration_milliseconds_count

This feature produces additional metrics and it's subject to Davis data units (DDU) licensing.

Labels for Kubernetes service

On the Kubernetes service page, the Kubernetes service labels are now displayed in the Properties and tags section.

Histogram metrics in the Istio metrics section

On the Kubernetes workload, namespace, and service pages, a new Response time chart is added to the Istio metrics section.
