Consumer lag growing on payments-events, partition 7
Group fraud-scoring-v3 is 1.4M messages behind on broker-3 and has grown linearly for 22 minutes. Root cause points to a single slow consumer holding back rebalance progress.

The goal is not another generic dashboard. The report highlights what is unhealthy, why it matters operationally, and what to do next.
Group fraud-scoring-v3 is 1.4M messages behind on broker-3 and has grown linearly for 22 minutes. Root cause points to a single slow consumer holding back rebalance progress.
28 partitions have ISR 2 instead of target 3 since broker-9 rejoined the cluster. Replica fetcher throttle is currently capped at 1 MB/s which is too low for catch-up before the next retention sweep.
42 ISR transitions in the last hour all on partitions led by broker-5. JVM GC pauses on that broker correlate with the pattern and indicate an instability precursor.
