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?
You can enable maxDataPoints
in query options with this setting in plugin.json
:
"queryOptions": {
"maxDataPoints": true
},
This feature is not documented...
