JSON API Grafana Datasource

The JSON Datasource executes requests against arbitrary backends and parses JSON response into Grafana dataframes.

Installation

To install this plugin using the grafana-cli tool:

 grafana-cli plugins install simpod-json-datasource

See here for more information.

Setup

When adding datasource add your API endpoint to the URL field. That's where datasource will make requests to.

Datasource setup

If you want to add custom headers, keep Access set to Server.

API

An OpenAPI definition is at openapi.yaml. You can explore it using Swagger Editor.

To work with this datasource the backend needs to implement 4 endpoints:

GET / with 200 status code response. Used for "Test connection" on the datasource config page.
POST /metrics to return available metrics.
POST /metric-payload-options to return a list of metric payload options.
POST /query to return panel data or annotations.

Those 3 endpoints are optional:

POST /variable to return data for Variable of type Query.
POST /tag-keys returning tag keys for ad hoc filters.
POST /tag-values returning tag values for ad hoc filters.

/metrics

POST /metrics

In Panel > Queries page. When configuring a query request using Builder mode, it will send the request to obtain the available metrics. The request body will carry the current metric and payload. In the Builder mode, if the reloadMetric value in the load configuration is true, the api will also be triggered when the value is modified / switched.

Example request:

{}

Or.

{
  "metric": "DescribeMetricList",
  "payload":{
    "cloud": "cf6591c5dad211eaa22100163e120f6e",
    "namespace": "MySQL"
  }
}

Example response:

[{
  "label": "Describe metric list", // Optional. If the value is empty, use the value as the label
  "value": "DescribeMetricList", // The value of the option.
  "payloads": [{ // Configuration parameters of the payload.
    "label": "Namespace", // The label of the payload. If the value is empty, use the name as the label.
    "name": "namespace", // The name of the payload.
    "type": "select", // If the value is select, the UI of the payload is a radio box. If the value is multi-select, the UI of the payload is a multi selection box; if the value is input, the UI of the payload is an input box; if the value is textarea, the UI of the payload is a multiline input box. The default is input.
    "placeholder": "Please select namespace", // Input box / selection box prompt information.
    "reloadMetric": true, // Whether to overload the metrics API after modifying the value of the payload.
    "width": 10, // Set the input / selection box width to a multiple of 8px. 
    "options": [{ // If the payload type is select / multi-select, the list is the configuration of the option list.
      "label": "acs_mongodb", // The label of the payload select option.
      "value": "acs_mongodb", // The label of the payload value.
    },{
      "label": "acs_rds",
      "value": "acs_rds",
    }]
  },{
    "name": "metric",
    "type": "select"
  },{
    "name": "instanceId",
    "type": "select"
  }]
},{
  "value": "DescribeMetricLast",
  "payloads": [{
    "name": "namespace",
    "type": "select"
  },{
    "name": "metric",
    "type": "select"
  },{
    "name": "instanceId",
    "type": "multi-select"
  }]
}]

The display is as follows: Metrics in builder Mode

/metric-payload-options

POST /metric-payload-options

When the payload type is select or multi-select and the payload options configuration is empty, expanding the drop-down menu will trigger this API. The request body will carry the current metric and payload.

Example Request:

{
  "metric":"DescribeMetricList", // Current metric.
  "payload": { // Current payload.
    "namespace":"acs_ecs"
  },
  "name":"cms_metric" // The payload name of the option list needs to be obtained.
}

Example Response:

[{ 
  "label": "CPUUtilization",
  "value": "CPUUtilization"
},{
  "label": "DiskReadIOPS",
  "value": "DiskReadIOPS"
},{
  "label": "memory_freeutilization",
  "value": "memory_freeutilization"
}]

The display is as follows: Metric options in builder Mode

/query

POST /query

Example request:

{
  "panelId": 1,
  "range": {
    "from": "2016-10-31T06:33:44.866Z",
    "to": "2016-10-31T12:33:44.866Z",
    "raw": {
      "from": "now-6h",
      "to": "now"
    }
  },
  "rangeRaw": {
    "from": "now-6h",
    "to": "now"
  },
  "interval": "30s",
  "intervalMs": 30000,
  "maxDataPoints": 550,
  "targets": [
     { "target": "Packets", "refId": "A", "payload": { "additional": "optional json" } },
     { "target": "Errors", "refId": "B" }
  ],
  "filters": [{
    "key": "City",
    "operator": "=",
    "value": "Berlin"
  }]
}

Response body can contain anything that is or can be converted to a Grafana DataFrame using this function. Returned data will be mapped to a DataFrame through that.

Example response (metric value as a float , unix timestamp in milliseconds):

[
  {
    "target":"pps in",
    "datapoints":[
      [622,1450754160000],
      [365,1450754220000]
    ]
  },
  {
    "target":"pps out",
    "datapoints":[
      [861,1450754160000],
      [767,1450754220000]
    ]
  },
  {
    "target":"errors out",
    "datapoints":[
      [861,1450754160000],
      [767,1450754220000]
    ]
  },
  {
    "target":"errors in",
    "datapoints":[
      [861,1450754160000],
      [767,1450754220000]
    ]
  }
]

[
  {
    "columns":[
      {"text":"Time","type":"time"},
      {"text":"Country","type":"string"},
      {"text":"Number","type":"number"}
    ],
    "rows":[
      [1234567,"SE",123],
      [1234567,"DE",231],
      [1234567,"US",321]
    ],
    "type":"table"
  }
]

The relation between target in request and response is 1:n. You can return multiple targets in response for one requested target.

Payload

Sending additional data for each metric is supported via the Payload input field that allows you to enter any JSON string.

For example, when { "additional": "optional json" } is entered into Payload input, it is attached to the target data under "payload" key:

{ "target": "upper_50", "refId": "A", "payload": { "additional": "optional json" } }

You can also enter variables:

Additional data variable input

/variable

POST /variable

Example request body:

{
  "payload":{"target":"systems"},
  "range":{
    "from":"2022-02-14T08:09:32.164Z",
    "to":"2022-02-21T08:09:32.164Z",
    "raw":{"from":"now-7d","to":"now"}
  }
}

"payload" is value from your input in Variable edit form.

Example response

[
  {"__text":"Label 1", "__value":"Value1"},
  {"__text":"Label 2", "__value":"Value2"},
  {"__text":"Label 3", "__value":"Value3"}
]

DataFrame is also supported.

/tag-keys

POST /tag-keys

Example request body

{ }

The tag keys api returns:

[
    {"type":"string","text":"City"},
    {"type":"string","text":"Country"}
]

/tag-values

POST /tag-values

Example request body

{"key": "City"}

The tag values api returns:

[
    {"text": "Eins!"},
    {"text": "Zwei"},
    {"text": "Drei!"}
]

v0.6.0

New Builder mode mainly implemented by @MicroOps-cn, huge thanks! 🎉 . See docs for details.

⚠️ Breaking change:

Fully implement /metrics endpoint. Also /metric-payload-options endpoint is recommended to be implemented.

TLDR for start, you can just change endpoint path from /search to /metrics and it should continue working.

v0.4.0

This adds support for Query Variables. They now call /variable endpoint instead of /search.

If you've used this datasource with Query Variables before, it will stop working for you probably. Open an issue for support.

Breaking Changes

Removed Format As input and with that a type field in request.
Field target.data in request was renamed to target.payload (edit your Dashboard's JSON for easy migration).
You should resave your variables as the legacy support has been dropped (it requires { query: string, format: string } shape) https://github.com/simPod/GrafanaJsonDatasource/commit/77a042f56f334ee1e48b396a7a459cea028d0b3d

Constraint is set to Grafana 8.0.0+

v0.2.6

Query Variables now have Raw JSON switch. When enabled, the query string is parsed as a JSON object. Otherwise when disabled, the query string is placed into a target key to create a JSON object.
