Package simplejson provides a Go implementation for Grafana's SimpleJSON datasource: https://grafana.com/grafana/plugins/grafana-simple-json-datasource A simplejson server is an HTTP server that supports one or more handlers. Each handler can support multiple targets, each of which can be supported by a timeseries or table query. Optionally tag can be used to alter the behaviour of the query (e.g. filtering what data should be returned). Finally, a handler can support annotation, i.e. a set of timestamps with associated text. To create a SimpleJSON server, create a Server and run it: This starts a server, listening on port 8080, with one target "my-target", served by myHandler. A handler serves incoming requests from Grafana, e.g. queries, requests for annotations or tag. The Handler interface contains all functions a handler needs to implement. It contains only one function (Endpoints). This function returns the Grafana SimpleJSON endpoints that the handler supports. Those can be: Here's an example of a handler that supports timeseries queries: SimpleJSON supports two types of query responses: timeseries responses and table responses. Timeseries queries return values as a list of timestamp/value tuples. Here's an example of a timeseries query handler: Table Queries, on the other hand, return data organized in columns and rows. Each column needs to have the same number of rows: The /annotations endpoint returns Annotations: NOTE: this is only called when using the SimpleJSON datasource. simPod / GrafanaJsonDatasource does not use the /annotations endpoint. Instead, it will call a regular /query and allows to configure its response as annotations instead. The /tag-keys and /tag-values endpoints return supported keys and key values respectively for your data source. A Grafana dashboard can then be confirmed to show those keys and its possible values as a filter. The following sets up a key & key value handler: When the dashboard performs a query with a tag selected, that tag & value will be added in the request's AdHocFilters. simplejson exports two Prometheus metrics for performance analytics: For information on query arguments and tags, refer to the documentation for those data structures.
