One, Grafana powerful drawing tool

• Introduction to
  Grafana Grafana is an open source measurement analysis and visualization suite. It is often used as a visualization of time series data and application analysis in infrastructure. It is also widely used in other fields including industrial sensors, home automation, weather and process control, etc. Grafana supports many different data sources. Each data source has a specific query editor, and the customized features and functions of the editor are public specific data sources. The following data sources are officially supported: Graphite, InfluxDB, OpenTSDB, Prometheus, Elasticsearch, CloudWatch and KairosDB. The query language and capabilities of each data source are different. You can combine data from multiple data sources into a dashboard, but each panel is bound to a specific data source, and it belongs to a specific organization. Let's take a look at grafana together.
