Removed unneeded stuff and vendored the dep

Removed all other as they can be easily re-added from source: <github.com/grafana-tools/sdk>.

Grafana SDK Go Report Card

SDK for Go language offers a library for interacting with Grafana server from Go applications. It realizes many of HTTP REST API calls for administration, client, organizations. Beside of them it allows creating of Grafana objects (dashboards, panels, datasources) locally and manipulating them for constructing dashboards programmatically. It would be helpful for massive operations on a large set of Grafana objects.

It was made foremost for autograf project but later separated from it and moved to this new repository because the library is useful per se.

Library design principles

  1. SDK offers client functionality so it covers Grafana REST API with its requests and responses as close as possible.
  2. SDK maps Grafana objects (dashboard, row, panel, datasource) to similar Go structures but not follows exactly all Grafana abstractions.
  3. It doesn't use any logger, instead API functions could return errors where it need.
  4. Prefere no external deps except Go stdlib.
  5. Cover SDK calls with unit tests.

Examples GoDoc

	board := sdk.NewBoard("Sample dashboard title")
	board.ID = 1
	board.Time.From = "now-30m"
	board.Time.To = "now"
	row1 := board.AddRow("Sample row title")
	row1.Add(sdk.NewGraph("Sample graph"))
	graph := sdk.NewGraph("Sample graph 2")
	target := sdk.Target{
		RefID:      "A",
		Datasource: "Sample Source 1",
		Expr:       "sample request 1"}
	graph.AddTarget(&target)
	row1.Add(graph)
	grafanaURL := "http://grafana.host"
	c := sdk.NewClient(grafanaURL, "grafana-api-key", sdk.DefaultHTTPClient)
	response, err := c.SetDashboard(context.TODO() ,*board, sdk.SetDashboardParams{
		Overwrite: false,
	})
	if err != nil {
		fmt.Printf("error on uploading dashboard %s", board.Title)
	} else {
		fmt.Printf("dashboard URL: %v", grafanaURL+*response.URL)
	}

The library includes several demo apps for showing API usage:

You need Grafana API key with admin rights for using these utilities.

Installation Build Status

Of course Go development environment should be set up first. Then:

go get github.com/grafana-tools/sdk

Dependency packages have included into distro. govendor utility used for vendoring. The single dependency now is:

go get github.com/gosimple/slug

The "slugify" for URLs is a simple task but this package used in Grafana server so it used in the SDK for the compatibility reasons.

Status of REST API realization Coverage Status

Work on full API implementation still in progress. Currently implemented only create/update/delete operations for dashboards and datasources. State of support for misc API parts noted below.

API Status
Authorization API tokens and Basic Auth
Annotations partially
Dashboards partially
Datasources +
Alert notification channels +
Organization (current) partially
Organizations partially
Users partially
User (actual) partially
Snapshots partially
Frontend settings -
Admin partially

There is no exact roadmap. The integration tests are being run against the following Grafana versions:

With the following Go versions:

  • 1.14.x
  • 1.13.x
  • 1.12.x
  • 1.11.x

I still have interest to this library development but not always have time for it. So I gladly accept new contributions. Drop an issue or contact me.
