Is your feature request related to a problem? Please describe.

Hello team, I am trying to add exemplars to calls_total metric for RED metrics and I tried calling setExemplars method here. But, I see the calls_total metric is being dropped to decimals. For example, we have a service that have 14k calls/sec but the metric is being dropped to 0.5 calls/sec. Removing setExemplars method fixes the issue.

Any insights here would really help. Thanks in advance

Describe the solution you'd like

I've tried restricting the number of exemplars to 5 per datapoint and it seems to work fine

The spanmetrics processor is deprecated, but I believe this issue is also applicable to the spanmetrics connector. Should we relabel with spanmetrics connector @crobert-1 ?

Hello @aishyandapalli, can you share some more context around this change? Are you attempting to add this as a feature to the processor/connector?

I tried calling setExemplars method here.

Can you share what the method call looks like that you're adding? It would be helpful to see what the inputs are to further debug.

We have worked this out with spanmetrics connector and it looks good now. We completely moved from processor to connector and everything looks fine now. Closing the issue
