Did you create dashboards in Grafana yourself? How did you maintain them?

Yes, I have created dashboards in Grafana for monitoring infrastructure and applications. I usually start by defining key metrics that are important to track — for example, CPU load, memory usage, service response time, and error count.

To support dashboards:

• I regularly update panels when architecture or requirements change.
• I set up alerts based on metrics to respond promptly to incidents.
• I optimize queries to data sources to ensure dashboards load quickly.
• I document the purpose of each panel and metric for the team.

An example of a simple query in Grafana for Prometheus:

rate(http_requests_total[5m])

This query shows the request rate over the last 5 minutes, helping to assess the load on the service.
