Facing issue to collect frequently changing datapoints using async gauge.

[ychaydhari]

Hi,
We have a few data points which vary very frequently within 1-2 secs. I'm using guageBuilder to collect this metric. but few data points are not able to capture.

private final Meter meter =
GlobalOpenTelemetry.meterBuilder("com.rs.mv.cm.stats")
.build();

meter.gaugeBuilder(OtelConstants.TOTAL_INUSE_CONNCTIONS)
.setDescription("Total number of in use connections.")
.setUnit("unit")
.buildWithCallback(
r -> {
r.record(account.getConnectionsInUse());
}
});

Can someone have any other way to capture this type of data point? which are very frequent within 1-2 secs?

Can you use a histogram?

Hi @trask, Do we support synchronous gauges? using histogram not getting proper values.

Hey @ychaydhari ,
Not yet - there's an open spec issue about sync gauges (open-telemetry/opentelemetry-specification#2318).
