'null' consumer group #332

Open daodennis-zz opened 6 years ago

daodennis-zz commented 6 years ago

After updating to Burrow 1.0 I noticed we're receiving alerts for a 'null' consumer group and it has no status. This is for info from a 0.8.x cluster.

The Kafka consumer groups you are monitoring are currently showing problems. The following groups are in a problem state (groups not listed are OK):
Cluster: kafka
Group: null
Status: 
Complete: 1
Errors: 24 partitions have problems

You're going to need to look at the consumer group list for the cluster, and dump the raw data for those groups. The likely answer is that Burrow is now picking up some stale information from Zookeeper that wouldn't have been alerted on previously (due to the changes in how completeness is handled now).
