> [ducktests] Fix the JMX metric registry MBean lookup
> ----------------------------------------------------

> Key: IGNITE-29049
> URL: https://issues.apache.org/jira/browse/IGNITE-29049
> Project: Ignite
> Issue Type: Task
> Reporter: Maksim Davydov
> Assignee: Maksim Davydov
> Priority: Minor
> Labels: ducktests, ise
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The MBean name of a metric registry is spelled out at every call site, and
> two of
> those patterns are wrong:
> * the rebalance metrics use '.*group=cacheGroups.*name="%s"', which requires
> the
> quotes unconditionally - the JMX exporter omits them for a purely
> alphanumeric
> name, so the registry of such a cache group is not found at all;
> * no pattern is anchored, so a registry whose name is a prefix of another one
> ("myCache" against "myCacheV2") answers with the wrong bean.
> Put the pattern in one place (metric_registry_pattern), add
> value()/bool_value()
> for reading a single valued attribute, and cover both cases with a check.
