Connection Count Approaching Limit
warningWhen active connection count approaches configured maximum, new clients will be rejected, causing connection failures and application errors.
Monitor kafka.network.connection_count approaching max.connections.per.broker configured limit. Alert when > 80% of max connections are active.
1. Increase max.connections.per.broker: Raise connection limit if resources permit. 2. Check for connection leaks: Identify clients not properly closing connections. 3. Review connection pooling: Ensure clients are reusing connections efficiently. 4. Monitor per-client connections: Identify which clients have excessive connections. 5. Enable connection quotas: Use connection rate quotas to prevent abuse. 6. Scale broker count: Distribute connections across more brokers.
