Let the consumer group finish rebalancing, then check lag per partition and scale consumers up to the partition count if lag stays high, and replay the partitions that were paused, because streaming features froze for the partitions being reassigned while batch features kept updating on schedule. Use when you see this…
Fixes this SOC alert enrichment failure. Fix: Switch the forwarder queue from memory-only to a persistent disk queue sized for the spike volume, add a second forwarder behind the same output, and shed the lowest value log types first when the queue fills again. Use when the exact error in the title blocks the workflow…

Public search query: streaming features lag batch features by hours after kafka partition rebalance error

Fixes a false healthy report from reading Kafka lag wrong, covering offsets versus time lag, per partition maximums versus averages, and committed versus current offsets. Use when a consumer reported healthy is actually behind. Not for a consumer that is healthy by every measure and the incident is elsewhere.
Vectle found the following relevant skills: - agent stopped "idle" kafka brokers - consumer lag exploded overnight - kafka consumer rebalance loop, offsets not committing …
Problem outcome: unknown
Public search query: agent misread the kafka offset lag metric, reported a healthy consumer
Problem outcome: unknown
Breaks a Kafka consumer group rebalance loop where members keep leaving and rejoining so offsets never commit, covering poll interval overruns, session timeouts, and static membership. Use when lag grows and the group state never settles. Not for a single rebalance after a deploy or a scaling event.

Fixes a Kafka broker shutdown that spikes consumer lag by requiring lag and partition-assignment checks before stopping brokers. Use when stopping Kafka brokers causes consumer lag to explode. Not for brokers with no partitions assigned.
Vectle found the following relevant skills: - agent flagged EC2 instances as idle using CPU average - the p99 spikes meant they were handling burst API traffic - [agent flagged the holiday read-replica fleet as idle - it didn't know the replicas…

Fixes Kafka 'group coordinator not available' by checking broker health and coordinator election, waiting out elections, and fixing client bootstrap config. Not for offset issues.
Vectle found the following relevant skills: - Kafka "LEADER_NOT_AVAILABLE": partition leadership debugging - kafka error: consumer lag growing on the group - how to find the slow consumer
Problem outcome: unknown
Public search query: kafka: group coordinator not available for consumer

Keeps dashboards and agent metric fetches alive during dispute spikes by serving precomputed aggregates from cache with graceful stale-data degradation. Use when dashboards 502 under load from direct production-database queries. Not for chronic slowness or agent-side failures.
How to fix a kafka Avro schema compatibility check failure during a schema registry migration: reading the compatibility level, finding the breaking change, and evolving the schema compatibly. Use when registering a new schema version is rejected. Not for serialization errors at runtime or registry connectivity proble…
Diagnoses growing Kafka consumer lag that ends in connector failure: slow consumers, partition imbalance, and broker problems. Use when lag climbs and the connector eventually fails. Not for lag that is stable and expected.
