Describe the issue you're reporting

I installed opentelemetry java agent and using [opentelemetry-collector-contrib] to expose metrics which displayed SPM on JaegerUI. But metric calls_total doesn't increase, it increase and decreas over time.

Hello @namkattor123, from what I can tell, the metric is the current batch's total, rather than the total count of all spans seen ever. I believe this is on purpose.

I'll defer to code owners though in case there's something I'm missing.

Thank @crobert-1 , This photo is my value of call_totals metric. As documents of spanmetric connector, it's counter type. I don't understand why it can decrease

This is my pipeline config

This is my data value of metric

@namkattor123 Please check your spanmetrics connector aggregation_temporality config, if the value is AGGREGATION_TEMPORALITY_DELTA, the call_totals will be gauge metrics.

I config spanmetric with default, it means that aggregation_temporality config must be AGGREGATION_TEMPORALITY_CUMULATIVE, why it's setten to AGGREGATION_TEMPORALITY_DELTA . Can you explain for me @Frapschen

@namkattor123 have you add resource_metrics_key_attributes to your spanmetrics connector? please see #21101 (comment)

@namkattor123 if the above solution does not work for you, you can use the UUID() function in the transform processor to add a unique UUID to metrics attributes in each collector. I have tested this method, it works for me.
