HTTP API

Annotations HTTP API

Enterprise Open source

Annotations resources / actions

This is the API documentation for the new Grafana Annotations feature released in Grafana 4.6. Annotations are saved in the Grafana database (sqlite, mysql or postgres). Annotations can be global annotations that can be shown on any dashboard by configuring an annotation data source - they are filtered by tags. Or they can be tied to a panel on a dashboard and are then only shown on that panel.

Find Annotations

GET /api/annotations?from=1506676478816&to=1507281278816&tags=tag1&tags=tag2&limit=100

Example Request:

GET /api/annotations?from=1506676478816&to=1507281278816&tags=tag1&tags=tag2&limit=100 HTTP/1.1
Accept: application/json
Content-Type: application/json
Authorization: Basic YWRtaW46YWRtaW4=

Query Parameters:

from: epoch datetime in milliseconds. Optional.
to: epoch datetime in milliseconds. Optional.
limit: number. Optional - default is 100. Max limit for results returned.
alertId: number. Optional. Find annotations for a specified alert.
dashboardId: number. Optional. Find annotations that are scoped to a specific dashboard
panelId: number. Optional. Find annotations that are scoped to a specific panel
userId: number. Optional. Find annotations created by a specific user
type: string. Optional. alert|annotation Return alerts or user created annotations
tags: string. Optional. Use this to filter global annotations. Global annotations are annotations from an annotation data source that are not connected specifically to a dashboard or panel. To do an “AND” filtering with multiple tags, specify the tags parameter multiple times e.g. tags=tag1&tags=tag2.

Example Response:

HTTP/1.1 200
Content-Type: application/json
[
    {
        "id": 1124,
        "alertId": 0,
        "dashboardId": 468,
        "panelId": 2,
        "userId": 1,
        "userName": "",
        "newState": "",
        "prevState": "",
        "time": 1507266395000,
        "timeEnd": 1507266395000,
        "text": "test",
        "metric": "",
        "tags": [
            "tag1",
            "tag2"
        ],
        "data": {}
    },
    {
        "id": 1123,
        "alertId": 0,
        "dashboardId": 468,
        "panelId": 2,
        "userId": 1,
        "userName": "",
        "newState": "",
        "prevState": "",
        "time": 1507265111000,
        "text": "test",
        "metric": "",
        "tags": [
            "tag1",
            "tag2"
        ],
        "data": {}
    }
]

Starting in Grafana v6.4 regions annotations are now returned in one entity that now includes the timeEnd property.

Create Annotation

Creates an annotation in the Grafana database. The dashboardId and panelId fields are optional. If they are not specified then a global annotation is created and can be queried in any dashboard that adds the Grafana annotations data source. When creating a region annotation include the timeEnd property.

The format for time and timeEnd should be epoch numbers in millisecond resolution.

POST /api/annotations

Example Request:

POST /api/annotations HTTP/1.1
Accept: application/json
Content-Type: application/json

{
  "dashboardId":468,
  "panelId":1,
  "time":1507037197339,
  "timeEnd":1507180805056,
  "tags":["tag1","tag2"],
  "text":"Annotation Description"
}

Example Response:

HTTP/1.1 200
Content-Type: application/json

{
    "message":"Annotation added",
    "id": 1,
}

The response for this HTTP request is slightly different in versions prior to v6.4. In prior versions you would also get an endId if you where creating a region. But in 6.4 regions are represented using a single event with time and timeEnd properties.

Create Annotation in Graphite format

Creates an annotation by using Graphite-compatible event format. The when and data fields are optional. If when is not specified then the current time will be used as annotation’s timestamp. The tags field can also be in prior to Graphite 0.10.0 format (string with multiple tags being separated by a space).

POST /api/annotations/graphite

Example Request:

POST /api/annotations/graphite HTTP/1.1
Accept: application/json
Content-Type: application/json

{
  "what": "Event - deploy",
  "tags": ["deploy", "production"],
  "when": 1467844481,
  "data": "deploy of master branch happened at Wed Jul 6 22:34:41 UTC 2016"
}

Example Response:

HTTP/1.1 200
Content-Type: application/json

{
    "message":"Graphite annotation added",
    "id": 1
}
