Kafka Consumer Group Monitoring
Monitor consumer lag, track partition assignments, and optimize throughput with intelligent rebalancing recommendations and real-time performance insights.
Consumer Group Challenges
Hidden consumer issues that can cripple your real-time applications
Consumer Lag Buildup
Lag accumulation goes unnoticed until it becomes critical, causing processing delays and data staleness.
Partition Imbalance
Uneven partition distribution leads to some consumers being overloaded while others sit idle.
Rebalancing Issues
Frequent or slow rebalancing operations cause processing interruptions and increased latency.

Frequently Asked Questions
Consumer lag is the difference between the latest message offset in a partition and the offset of the last message consumed by a consumer group. High lag indicates that consumers are falling behind, which can lead to stale data, delayed processing, and potential data loss if retention periods expire.
KLogic monitors the committed offset for each consumer and compares it to the high watermark (latest offset) for each partition. We track lag in both message count and time-based metrics, showing how far behind each consumer is in real-time.
Rebalancing occurs when consumers join or leave a group, when partitions are added to topics, or when consumers fail health checks. KLogic tracks rebalancing events, measures their duration, and identifies patterns that may indicate configuration issues.
Yes, KLogic provides customizable lag alerts based on message count, time-based lag, or rate of lag increase. You can set different thresholds for different consumer groups and route alerts to Slack, PagerDuty, email, or webhooks.
KLogic provides recommendations for consumer scaling, partition assignment strategies, and configuration tuning. We analyze throughput patterns, identify slow consumers, and suggest optimal consumer counts based on your workload.
Yes, KLogic can monitor unlimited consumer groups across multiple Kafka clusters. You can organize groups by application, team, or environment and create custom dashboards for different stakeholders.
