2, Introduction to Grafana

What is Grafana

Grafana is a visual Dashboard with beautiful charts and layout display, fully functional measurement Dashboard and graphic editor. Support Graphite, zabbix, InfluxDB, Prometheus and OpenTSDB as data sources.

Grafana features

  • 1. grafana has fast and flexible client charts. The panel plug-ins have many different visual indicators and logs. The official library has a wealth of dashboard plug-ins, such as heat map, line chart, chart and other display methods, which makes our complex data display beautiful and elegant.
  • 2. Grafana supports many different time series data (data sources) storage backend. Each data source has a specific query editor. The following data sources are officially supported: Graphite, infoxdb, opensdb, prometheus, elasticsearch and cloudwatch. The query language and function of each data source are obviously different. You can combine data from multiple data sources into one dashboard, but each panel should be bound to a specific data source belonging to a specific organization
  • 3. Alerts in grafana allow you to attach rules to dashboard panels. When you save the dashboard, Gravana extracts the alert rules into a separate alert rule store and schedules them for evaluation. The alarm message can also be pushed to the mobile terminal through nails, mailboxes, etc. But at present, grafana only supports the alarm of graph panel.
  • 4. Grafana uses rich event annotation charts from different data sources. Hovering over the event will display complete event metadata and tags;
  • 5. Grafana's use of ad hoc filters allows dynamic creation of new key / value filters that are automatically applied to all queries using the data source.
