Summary: MetricRegistryMBean doesn't show histogram values in case
when histogram name contains underscore character
Key: IGNITE-12768
URL: https://issues.apache.org/jira/browse/IGNITE-12768
Project: Ignite
Issue Type: Bug
Reporter: Andrey N. Gura
Fix For: 2.8.1
{{MetricRegistryMBean}} doesn't show histogram values in case when histogram
name contains underscore character.
The problem in {{MetricRegistryMBean.searchHistogram()}} method which relies on
first underscore character in the fully qualified metric name. This method also
use relatively old and not effective API for string parsing (this API
implementation is synchronized). It should be replaced by simple
{{String.lastIndexOf()}} for example.
