Interview Question

Your centralized logging pipeline stops ingesting logs from multiple services. How do you debug?

Key Points to Cover
  • Check log forwarders/agents for errors
  • Validate ingestion pipeline (Kafka/Fluentd/Logstash)
  • Check disk/network saturation on collectors
  • Inspect schema/parsing errors in pipeline
  • Add redundancy and retry mechanisms
