Feature Request: OpenTSDB use interval variable for downsampling

[RalfGraefeIntel]

Hello,

For OpenTSDB I would like to use interval template variables for the DownSample field. This should hopefully allow to dynamically downsample the result set based on zoom level.

Looking at the code I could imagine that its as simple as that (but I'm not a JavaScript expert):
in src/app/services/opentsdb/opentsdbDatasource.js line 152
replace
query.downsample = target.downsampleInterval + "-" + target.downsampleAggregator;
with
query.downsample = templateSrv.replace(target.downsampleInterval) + "-" + target.downsampleAggregator;

Could that work? I wanted to test myself but could not get the grunt command to run :[ .
In addition an autocomplete function that only lists variables of type interval would be nice.

using in downsample:

Thanks

Yes, this is a very simple enhancement to implement. Will add this to 1.9.1 patch release and implemented tomorrow.

Hi @torkelo . As I told you some weeks ago in (#914 (comment))

This downsampling feature depending on the time range ( and the consolidation function related to each metric ) should be a common feature with independence of the data backend .

I'll be pleased to discuss on this issue again if needed.
