I have all kafka broker metrics exported to prometheus and trying to build grafana dashboard. Kafka version i am using is 2.5.0 I am confused about kafka.server:type=KafkaRequestHandlerPool,name=RequestHandlerAvgIdlePercent metric. according to kafka documentation it is "The average fraction of time the request handler threads are idle and value should be between 0 and 1, ideally > 0.3" but when i try to query the metric from prometheus i do not find any metric with name "kafka_server_kafkarequesthandlerpool_requesthandleravgidlepercent". Instead the metric i find is "kafka_server_kafkarequesthandlerpool_requesthandleravgidlepercent_count". its value is not between 0 and 1 but a very large number. seems it is not a percent metric but some count metric whose value keep increasing. need help in interpreting this metric value. i googled for answer but could not find any.
Thanks, dsingh
