What metrics were on the Grafana dashboards and what specifically helped reduce MTTR?

Grafana dashboards for DevOps typically display metrics related to the performance and health of infrastructure and applications:

• CPU load and memory usage on servers
• Service response times (latency)
• Error rates
• Status and execution time of critical tasks
• Metrics on disk space and network

To reduce MTTR (Mean Time To Recovery), quick detection of anomalies and bottlenecks was key. For example, monitoring errors and response times allowed for prompt identification of failures, and alerts in Grafana integrated with notification systems (Slack, PagerDuty) ensured instant team notifications.

It was also useful to visually display service dependencies and logs, which sped up diagnostics and problem localization.
