It appears that the datadog reporter does not report histograms. I'll
file an issue to fix that.

Hi,
I followed [1] to define my own metric as:
val dropwizardHistogram = new com.codahale.metrics.Histogram(new
SlidingWindowReservoir(500))
histogram = getRuntimeContext
.getMetricGroup
.histogram("*feature_latency*", new
DropwizardHistogramWrapper(dropwizardHistogram))
and it is successfully shown up in the flink UI:

however, I couldn't find it in datadog. my flink conf looks like:
"metrics.reporter.dghttp.factory.class" ->
"org.apache.flink.metrics.datadog.DatadogHttpReporterFactory",
"metrics.scope.operator" -> "flink.op",
"metrics.scope.jm.job" -> "flink.jm.job",
"metrics.scope.jm <http://metrics.scope.jm>" -> "flink.jm
<http://flink.jm>",
"metrics.scope.tm <http://metrics.scope.tm>" -> "flink.tm
<http://flink.tm>",
"metrics.scope.tm.job" -> "flink.tm.job",
"metrics.scope.task" -> "flink.task",
Am I missing something that is necessary for datadog to report my
customized metrics?
Thanks,
Fanbin
