Consumers missing #523

Open hekmekk opened 6 years ago

hekmekk commented 6 years ago

kafka-manager version: 1.3.3.17 kafka-version: 0.11.0.0 os: Debian 8.6 (jessie)

I recently noticed consumers missing from the different views, that is they appear in neither /clusters/<cluster-name>/consumers nor /clusters/<cluster-name>/topics/<topic-name>/ under "Consumers consuming from this topic". However when asking the kafka tools (/usr/bin/kafka-consumer-groups) or burrow about consumers, they are listed. What I've done recently was an upgrade from 1.3.3.13 to 1.3.3.17 (a couple of weeks ago) without any changes to the configuration.

If this is not a problem on my side, I feel more people should've encountered this issue...

Do you required more information on this or does this sound familiar already?

Are they active consumers or old consumers?

hekmekk commented 6 years ago

They are active consumers (sorry for the late reply).

I'm also afraid I didn't look closely enough: The kafka-consumer-groups tool does list the "missing" consumer group, but has no detailed information on it. I assume such "consumer groups without anything interesting to say about them" fall victim to some sort of filter within kafka-manager, so that they will not be displayed?
