Hi guys, I am a developer who uses Micrometer for system monitoring. I really appreciate the ease of use of Micrometer.

I noticed that HdrHistogram is used in io.micrometer.core.instrument.distribution.TimeWindowPercentileHistogram. However, the current hdrHistogram uses some default construction parameters, so that the upper and lower bounds of the bucket of hdrHistogram are set to [1, 127] by default. This interval size cannot meet the needs of our usage scenarios, and there will be frequent resize operations, which will bring some performance overhead.

We hope that the internalHistogram can be exposed so that we can have some methods to customize the upper and lower bounds of the buckets in internalHistogram according to our needs. Thanks~
