Grafana is a cross-platform open source measurement analysis and visualization tool that can query and visualize the collected data and notify it in time. It mainly has the following six characteristics:
1. Display mode: fast and flexible client-side charts, panel plug-ins have many different ways of visual indicators and logs, and the official library has a wealth of dashboard plug-ins, such as heat maps, line charts, charts and other display methods;
2. Data source: Graphite, InfluxDB, OpenTSDB, Prometheus, Elasticsearch, CloudWatch and KairosDB, etc.;
3. Notification reminder: Define the alarm rules of the most important indicators in a visual way. Grafana will continuously calculate and send notifications, and get notifications through Slack, PagerDuty, etc. when the data reaches the threshold;
4. Mixed display: Mix different data sources in the same chart, you can specify the data source based on each query, or even customize the data source;
5. Annotation: Use rich event annotation charts from different data sources. Hovering the mouse over the event will display the complete event metadata and markup;
6. Filters: Ad-hoc filters allow new key/value filters to be dynamically created, and these filters are automatically applied to all queries that use the data source.
