Monitoring and Logging are critical practices in DevOps for tracking system performance, detecting issues, and diagnosing application errors in real time.
Monitoring tools like Prometheus, Datadog, Grafana, and CloudWatch provide insights into metrics like CPU usage, latency, and uptime. Logging tools like ELK Stack (Elasticsearch, Logstash, Kibana), Fluentd, or Loki capture detailed logs that help teams troubleshoot and audit activity.
Together, they enable alerting, root-cause analysis, and proactive incident response — ensuring that services remain reliable and transparent at scale.
