Step 1: Identify automated monitoring needs
To alert on lag thresholds, automation is needed to check lag regularly and trigger alerts.Step 2: Evaluate options
Running kafka-consumer-groups.sh periodically and parsing output fits this need; manual checks are unreliable; restarting consumers does not fix lag causes; increasing partitions affects throughput but not direct lag alerting.Final Answer:
Use a monitoring tool to periodically run kafka-consumer-groups.sh and parse lag values -> Option AQuick Check:
Automate lag checks with kafka-consumer-groups.sh [OK]
Quick Trick: Automate lag checks with scripts or monitoring tools [OK]
