How to export Spring Boot `http.server.requests` as Prometheus Histogram

[Rafael Dohms]

I have a Spring Boot setup, with micrometer and metrics turned on.
I have successfully used http.server.requests to export a Counter of how many requests are happening.

However, I'm now stuck trying to create a Histogram of response times for these same requests.

What I have tried so far:

• Tried to find a way to extract the Attributes as a Prometheus Histogram, but found no way to do this
• Set management.metrics.distribution.sla.http.server.requests: 1ms, 2ms, 5ms, 10ms, 20ms, 30ms to get a set of gauges that represent the buckets

Has anyone achieved this before? I'm currently thinking along the lines of recreating the _sum, _count and _bucket parts separately from the gauge but I have not yet figured out how to do the sum and count parts. Any direction is much appreciated.

Sorry, this is now missing the proper context.

I'm looking for the correct jmx_exporter configuration to achieve this.

Hi Rafael,

I am also facing a similar issue while exporting kafka connect metrics in histogram types.
Did you find a solution to this?

Found this: 

management.metrics.web.server.request.autotime.percentiles-histogram=true

Hope it helps.
