Hi Sigalit
Did you add the classpath to the META-INF.services folder of the reporter?

The content of my file is:
org.apache.flink.metrics.custom.NestedGaugePrometheusReporterFactory
Kind regards

hi
we have upgraded from flink 1.16 to 1.18 and our custom metric stopped working.
i saw in the release note of 1.17 that there was a change so i have defined the
following
metrics.reporters: otlp
metrics.reporter.otlp.factory.class:
xxx.flink.metrics.otlp.OpenTelemetryProtocolReporterFactory
metrics.reporter.otlp.interval: 30s
metrics.reporter.otlp.filter: XXXX
metrics.reporter.otlp.prefix: pipeline_
i have defined OpenTelemetryProtocolReporterFactory that implements
MetricReporterFactory
i verified the jar with my reporter and factory exists under flink/plugins
and still i get the following warning during deployment which indicates that my
reporter is not loaded

I am not sure why the new reporter is not loaded. i did not see any exception
Is there any additional configuration required?
Thanks
