Unnecessary Latency buckets getting created using Micrometer For Spring-boot Application

Question

Defined latency buckets for http.server.requests metric using below config for spring-boot application :

management.metrics.distribution.slo.http.server.requests=1ms,5ms,15ms,50ms

But it's creating intermediate buckets also. Can anyone help me explain how we can configure it properly so that intermediate buckets won't be created.

Example : Between 1ms to 5ms below are buckets getting created.

le="0.001",} 425928.0
le="0.001048576",} 425933.0
le="0.001398101",} 425971.0
le="0.001747626",} 426015.0
le="0.002097151",} 426019.0
le="0.002446676",} 426022.0
le="0.002796201",} 426028.0
le="0.003145726",} 426029.0
le="0.003495251",} 426030.0
le="0.003844776",} 426030.0
le="0.004194304",} 426030
le="0.005",} 426030

Answer 1

I think you also enabled percentile histograms (asked for those buckets) either from Java config or using this property:

management.metrics.distribution.percentiles-histogram.http.server.requests=true

or

management.metrics.distribution.percentiles-histogram.all=true
