Hi, I've deployed a few kafka brokers to test kafka out, for monitoring purposes I've configured our in-house monitoring system to poll the JMX MBeans exposed by Kafka.
It appears that some of the metrics exposed through JMX are pre-computed rates of change of quantities whose raw values are not available via JMX. Would it be possible for the MBeans to expose those raw values so rates, delta, etc can be computed on other time periods? I'm specifically thinking about the following metrics: avgflushms avgfetchrequestms avgproducerequestms bytesreadpersecond byteswrittenpersecond fetchrequestspersecond producerequestspersecond which are rates and averages. Having the following additional metrics (counters) would allow for more flexibility: totalflushms totalbytesread totalbyteswritten totalfetchrequestms totalproducerequestms Mathias.
