Denis Mekhanikov commented on IGNITE-13886:
-------------------------------------------
[~NSAmelchev] it seems that you've added these metrics. Do you think we can
convert buckets from nanoseconds to milliseconds?
> Change units of cache-related histograms to milliseconds

> Key: IGNITE-13886
> URL: https://issues.apache.org/jira/browse/IGNITE-13886
> Project: Ignite
> Issue Type: Improvement
> Reporter: Denis Mekhanikov
> Priority: Major
>
> Ignite has different metrics that have the "histogram" type:
> * tx.nodeSystemTimeHistogram
> * tx.nodeUserTimeHistogram
> * pme.DurationHistogram
> * pme.CacheOperationsBlockedDurationHistogram
> * cache.<cacheName>.GetTime
> * cache.<cacheName>.PutTime
> * cache.<cacheName>.RemoveTime
> * cache.<cacheName>.CommitTime
> * cache.<cacheName>.RollbackTime
> First four have buckets corresponding to the amount of time the operation
> took in milliseconds.
> Cache-related histograms are measured in nanoseconds, while it would be
> enough to use milliseconds there as well.
> It's hard to distinguish between 100000000 and 1000000000 nanoseconds
> visually.
> The following set of buckets should be used:
> * 1
> * 10
> * 100
> * 250
> * 1000
> The values are provided in milliseconds.
