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",

    "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

}

Status codes:

Get all correlations.

Query parameters:

page - Optional. Specify which page number to return. Use the limit parameter to specify the number of correlations per page. The default is page 1.
limit - Optional. Limits the number of returned correlations per page. The default is 100 correlations per page. The maximum limit is 1000 correlations in a page.
sourceUID - Optional. Specify a source datasource UID to filter by. This can be repeated to filter by multiple datasources.
