How is log analysis performed to identify system monitoring issues?

Log analysis for identifying issues in monitoring systems typically includes the following steps:

1. Log collection — aggregating logs from various system components.
2. Filtering and parsing — extracting important fields (time, log level, message, identifiers).
3. Anomaly detection — analyzing for errors, warnings, recurring patterns.
4. Event correlation — linking logs from different services to understand the sequence of events.
5. Visualization and alerting — using dashboards and notification systems for prompt response.

Automation often involves tools like ELK Stack (Elasticsearch, Logstash, Kibana) or Prometheus with Grafana.
