Jean-Daniel Cryans commented on HBASE-10755:
--------------------------------------------
[~stack] sure can, I just don't know which way to go. Is there a valid reason
why the histograms are upper casing the metrics? Looking over at the java.lang
MBeans, it seems to be the norm to upper case. But then Master.Server is all
lower case, Master.Balancer is mostly upper case, but at least we don't get it
mixed up for the same metric prefixes. I guess I'll got with changing
"namespace_" to "Namespace_".
> MutableHistogram is capitalizing the metric names

> Key: HBASE-10755
> URL: https://issues.apache.org/jira/browse/HBASE-10755
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.96.0
> Reporter: Jean-Daniel Cryans
> Priority: Minor
>
> Noticed something while looking at MBeans; some metric names are capitalized
> while others aren't. This has the unwanted property of changing the metric
> names sorting. For example:
> Namespace_default_table_t_region_0122d54a90c9dc191857daf11e8a047d_metric_scanNext_num_ops
> namespace_default_table_t_region_0122d54a90c9dc191857daf11e8a047d_metric_appendCount
> The reason for this is that {{MutableHistogram}} uses
> {{StringUtils.capitalize()}} on the metrics name (as create by
> {{MetricsRegionSourceImpl}} with "namespace_").
> I'm not sure what the intent was with capitalization, but either way it's a
> simple fix. [~eclark]?
