Bug Fix
Description of problem:
With 4.13 we added new metrics to the console (Epic ODC-7171 - Improved telemetry (provide new metrics), that collect different user and cluster metrics.
The cluster metrics include:
- which perspectives are customized (enabled, disabled, only available for a subset of users)
- which plugins are installed and enabled
These metrics contain the perspective name or plugin name which was unbounded. Admins could configure any perspective and plugin name, also if the perspective or plugin with that name is not available.
Based on the feedback in https://github.com/openshift/cluster-monitoring-operator/pull/1910 we need to reduce the cardinality and limit the metrics to, for example:
- perspectives: admin, dev, acm, other
- plugins: redhat, demo, other
Version-Release number of selected component (if applicable):
4.13.0
How reproducible:
Always
Steps to Reproduce:
On a cluster, you must update the console configuration, configure some perspectives or plugins and check the metrics in Admin > Observe > Metrics:
avg by (name, state) (console_plugins_info) avg by (name, state) (console_customization_perspectives_info)
On a local machine, you can use this console yaml:
apiVersion: console.openshift.io/v1 kind: ConsoleConfig plugins: logging-view-plugin: https://logging-view-plugin.logging-view-plugin-namespace.svc.cluster.local:9443/ crane-ui-plugin: https://crane-ui-plugin.crane-ui-plugin-namespace.svc.cluster.local:9443/ acm: https://acm.acm-namespace.svc.cluster.local:9443/ mce: https://mce.mce-namespace.svc.cluster.local:9443/ my-plugin: https://my-plugin.my-plugin-namespace.svc.cluster.local:9443/ customization: perspectives: - id: admin visibility: state: Enabled - id: dev visibility: state: AccessReview accessReview: missing: - resource: namespaces verb: get - id: dev1 visibility: state: AccessReview accessReview: missing: - resource: namespaces verb: get - id: dev2 visibility: state: AccessReview accessReview: missing: - resource: namespaces verb: get - id: dev3 visibility: state: AccessReview accessReview: missing: - resource: namespaces verb: get
And start the bridge with:
./build-backend.sh ./bin/bridge -config ../config.yaml
After that you can fetch the metrics in a second terminal:
Actual results:
curl -s localhost:9000/metrics | grep ^console_plugins
console_plugins_info{name="acm",state="enabled"} 1
console_plugins_info{name="crane-ui-plugin",state="enabled"} 1
console_plugins_info{name="logging-view-plugin",state="enabled"} 1
console_plugins_info{name="mce",state="enabled"} 1
console_plugins_info{name="my-plugin",state="enabled"} 1
curl -s localhost:9000/metrics | grep ^console_customization
console_customization_perspectives_info{name="dev",state="only-for-developers"} 1
console_customization_perspectives_info{name="dev1",state="only-for-developers"} 1
console_customization_perspectives_info{name="dev2",state="only-for-developers"} 1
console_customization_perspectives_info{name="dev3",state="only-for-developers"} 1
Expected results:
Less cardinality, that means, results should be grouped somehow.
