grafana-dashboards

Build a Grafana dashboard to monitor web application performance by selecting panel types like timeseries or stat, then writing PromQL queries to fetch request rates and latency metrics from Prometheus data sources.

PromQL is used in Grafana observability dashboards to query time-series metrics from data sources like Prometheus, enabling the visualization of system performance data across various panel types.

Set up alerting rules for high error rates in Grafana by configuring alert conditions within your dashboard panels, triggering notifications when PromQL queries detect an error rate exceeding 5%.

You can use templating to build dynamic Grafana dashboards by implementing variables, allowing panels to filter and display changing metric data dynamically based on selected variable values.

Panel types available for visualizing metrics in Grafana include timeseries for trend lines, stat for single values, gauge for ranges, and table for structured data, enabling diverse observability views.
