Brief description of grafana of ＃ yyds dry goods inventory ＃ Prometheus

Grafana Support many different types of time series databases （ Data sources ）, Each data source has a specific query editor , The editor customizes the features and functions exposed by specific data sources ,Grafana It can well support the characteristics of each data source .Grafana There are several data sources officially supported ：Graphite、InfluxDB、OpenTSDB、Prometheus、Elasticsearch、CloudWatch. Each data source has different query languages and functions . Users can combine data from multiple data sources into a single dashboard （Dashboard） On , But each panel （Panel） Are bound to specific data sources belonging to specific organizations .

Query Editor It can be understood as statement management , Each panel is provided with a Query Editor, You can write statements to effectively control the panel to display different charts in real time .Grafana Reference the query through the row in the query editor .
