downsampling.
gapFilling		 string
Parameters for filling in missing data.

Methods for filling gaps in data during downsampling.

  • NULL: Returns null as the metric value and timestamp as the timestamp value. This is also the default value.

downsampling.
maxPoints		 string (int64)
downsampling only includes one of these fields: maxPoints, gridInterval, or disabled

Maximum number of points per request.

This value must be greater than 10.
downsampling.
gridInterval		 string (int64)
