How to monitor summary metrics using JMX exporter

[anurag-appperfect]

For some metrics, it would be useful if we could see a few different percentiles (75, 95 and 99, for example) for metrics, which have constantly a lot of samples in short time periods. Can anybody help me to configure my java service to expose percentile metrics using jmx exporter ?

The exporter only exposes metrics as exposed by JMX. If you want/need histograms, you would need to either create JMX MBeans that expose the percentiles or do it in in Prometheus (time series database.)

Thank you for your answer, can you tell me a bit more about how we can achieve this in prometheus ?

Typically you would use a Histogram to instrument your code.

HistogramTest is a good example of usage.

I'd like to also be able to define MBeans that captures Summary metrics. Are we able to define this in the JMX configuration? I didn't see any examples related to Summary or Histogram.
