> Prometheus Metrics Server returns 500 (Internal Server Error) when a Remote Process Group
is used. The error message:
> {quote}{{java.lang.IllegalArgumentException: Incorrect number of labels.}}
>  {{at io.prometheus.client.SimpleCollector.labels(SimpleCollector.java:64)}}
>  {{at org.apache.nifi.reporting.prometheus.api.PrometheusMetricsUtil.createNifiMetrics(PrometheusMetricsUtil.java:405)}}
>  {{at org.apache.nifi.reporting.prometheus.PrometheusServer$MetricsServlet.doGet(PrometheusServer.java:74)}}
> {quote}
> Just because the labels number of `ACTIVE_REMOTE_PORT_COUNT`, `INACTIVE_REMOTE_PORT_COUNT`,
and `AVERAGE_LINEAGE_DURATION` are unmatched.
