6.2. Datasources for Knative Serving metering
The following ReportDataSources are examples of how Knative Serving can be used with OpenShift Container Platform metering.
6.2.1. Datasource for CPU usage in Knative Serving
This datasource provides the accumulated CPU seconds used per Knative service over the report time period.
YAML file
apiVersion: metering.openshift.io/v1
kind: ReportDataSource
metadata:
name: knative-service-cpu-usage
spec:
prometheusMetricsImporter:
query: >
sum
by(namespace,
label_serving_knative_dev_service,
label_serving_knative_dev_revision)
(
label_replace(rate(container_cpu_usage_seconds_total{container_name!="POD",container_name!="",pod_name!=""}[1m]), "pod", "$1", "pod_name", "(.*)")
*
on(pod, namespace)
group_left(label_serving_knative_dev_service, label_serving_knative_dev_revision)
kube_pod_labels{label_serving_knative_dev_service!=""}
)
6.2.2. Datasource for memory usage in Knative Serving
This datasource provides the average memory consumption per Knative service over the report time period.
YAML file
apiVersion: metering.openshift.io/v1
kind: ReportDataSource
metadata:
name: knative-service-memory-usage
spec:
prometheusMetricsImporter:
query: >
sum
by(namespace,
label_serving_knative_dev_service,
label_serving_knative_dev_revision)
(
label_replace(container_memory_usage_bytes{container_name!="POD", container_name!="",pod_name!=""}, "pod", "$1", "pod_name", "(.*)")
*
on(pod, namespace)
group_left(label_serving_knative_dev_service, label_serving_knative_dev_revision)
kube_pod_labels{label_serving_knative_dev_service!=""}
)
6.2.3. Applying Datasources for Knative Serving metering
You can apply the ReportDataSources by using the following command:
