Grafana is an open-source dashboard for data visualisation. It’s commonly used in tandem with Prometheus, using PromQL to query its data.
Questions:
- What are time series.
- What are metrics.
- How do I group by a specific column/field in PromQL?
- What exactly is time-series database? How does it differ?
Grafana visualises metrics and logs.
