Monitoring is showing '?' for counters when there is one-or-more inactive instance #2854
Description
Describe the bug
Description
I scale up and down my endpoints depending on the amount of msg. Every time there is an inactive instance for an endpoint then Monitoring is not showing numbers for the counters but '?' .
Only when inactive endpoints are auto cleaned up in the INSTANCES tab, the counters show numbers again.
I disable 'Track Instances' for all my endpoints in the Endpoint Heartbeats Configuration.
Expected behavior
It should ignore inactive endpoints and show numbers for the counters in the Monitoring overview.
Actual behavior
It shows '?' for all the ccounters:
When going to the INSTANCEs tab it shows the number for counters correctly for the active instance. I expect this number also in the overview.
Versions
ServicePulse v2.3.2 (but this bug is already for some time, I think when the Track Instances feature was introduced)
Steps to reproduce
Scale an endpoint up with one or more instances and then scale it back to 1.
Relevant log output
no logsAdditional Information
Workarounds
It used to be possible to remove inactive endpoints under the INSTANCES tab, so I could 'fix' it in that way, but this is not possible anymore.

Hi @RemyDuijkeren . We have reviewed this bug and added it to our bug fix queue. However, there is no ETA for when we will get to this bug as it may be prioritized behind other, more urgent, bugs. We will update this issue when it has a team assigned and work begins.

IsStale is being set in ServiceControl based on any of the instances, rather than all of the instances. This setting is used in many places in ServicePulse, so any fix will need to verify all usage points, and also verify behaviour against endpoints of type Track Instances/Do Not Track Instances
