grafana数据源最大数据点

Question

Developing a Grafana datasource plugin is there a way to change max number of datapoints returned to panels?

Request object passed to datasource.query function is like below:

{
  "range": { "from": "2015-12-22T03:06:13.851Z", "to": "2015-12-22T06:48:24.137Z" },
  "interval": "5s",
  "targets": [
    { "refId": "B", "target": "upper_75" },
    { "refId": "A", "target": "upper_90" }
  ],
  "format": "json",
  "maxDataPoints": 2495 //decided by the panel
}

As per code comment (from docs ) maxDataPoints is decided by the panel.

No way to override this value?

Answer 1

You can enable maxDataPoints in query options with this setting in plugin.json :

"queryOptions": {
   "maxDataPoints": true
},

This feature is not documented...
