User Story

As an OpenShift cluster admin
I want to be alerted if something cleared the LastImageTriggeredID in a BuildConfig
So that I am aware that cluster users are relying on deprecated behavior.

Acceptance Criteria

• Cluster administrators can use system information to identify if a build was triggered by having the LastImagechangeTriggerID cleared
• Deprecation notice regarding this behavior is visible in the web console.

Notes

After review with the monitoring team, we agreed to use Warning events rather than alerts. To properly create an alert for this behavior, we would have needed to introduce a metric with unbound cardinality. Such metrics can lead to performance degradation in the cluster monitoring system.

When the LastImageChangeTriggerID is cleared in a BuildConfig object, a warning event is created which should appear in relevant contexts within the Web Console.
