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

"label": "My Label",
"description": "Logs to Traces",
"type": "query",
"config": {
"field": "message",
"target": {},
}
}
JSON body schema:
- targetUID – Target data source uid.
- label – A label for the correlation.
- description – A description for the correlation.

Get all correlations
GET /api/datasources/correlations
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.
