Jack Baldry c1c48dd610 Use relative aliases for all non-current Grafana aliases (#60062) 
* Use relative aliases for all non-current Grafana aliases

Prevents non-latest documentation "stealing" the page away from latest
and through permanent redirects for latest pages that no longer exist.

The redirected pages are indexed by search engines but our robots.txt
forbids them crawling the non-latest page.

Correlations HTTP API

Correlations API

This API can be used to define correlations between data sources.

Create correlations

POST /api/datasources/uid/:sourceUID/correlations

Creates a correlation between two data sources - the source data source identified by sourceUID in the path, and the target data source which is specified in the body.

Example request:

POST /api/datasources/uid/uyBf2637k/correlations HTTP/1.1
Accept: application/json
Content-Type: application/json
Authorization: Bearer eyJrIjoiT0tTcG1pUlY2RnVKZTFVaDFsNFZXdE9ZWmNrMkZYbk
{
	"targetUID": "PDDA8E780A17E7EF1",
	"label": "My Label",
	"description": "Logs to Traces",
  "config": {
    "type": "query",
    "field": "message",
    "target": {},
  }
}

JSON body schema:

  • targetUID – Target data source uid.
  • label – A label for the correlation.
  • description – A description for the correlation.

Example response:

HTTP/1.1 200
Content-Type: application/json
{
  "message": "Correlation created",
  "result": {
    "description": "Logs to Traces",
    "label": "My Label",
    "sourceUID": "uyBf2637k",
    "targetUID": "PDDA8E780A17E7EF1",
    "uid": "50xhMlg9k",
    "config": {
      "type": "query",
      "field": "message",
      "target": {},
    }
  }
}

Status codes:

  • 200 – OK
  • 400 - Errors (invalid JSON, missing or invalid fields)
  • 401 – Unauthorized
  • 403 – Forbidden, source data source is read-only
  • 404 – Not found, either source or target data source could not be found
  • 500 – Internal error

Delete correlations

DELETE /api/datasources/uid/:sourceUID/correlations/:correlationUID

Deletes a correlation.

Example request:

DELETE /api/datasources/uid/uyBf2637k/correlations/J6gn7d31L HTTP/1.1
Accept: application/json
Content-Type: application/json

  "message": "Correlation deleted"
}

Status codes:

  • 200 – OK
  • 401 – Unauthorized
  • 403 – Forbidden, data source is read-only
