Symptoms
In ServicePulse, the monitoring endpoint list could hide all metrics for an endpoint and show ? placeholders even when some instances were still healthy.
This happened when any instance of the endpoint was stale.
Who's affected
Users monitoring endpoints with multiple instances where one or more instances become stale while at least one instance remains healthy.
Root cause
IsStale in GetMonitoredEndpoints was being set to true when any instance was stale.
This caused the whole endpoint to be treated as stale, even if other instances were healthy.
Confirmed workarounds
None
