Description

Custom metrics for custom replication endpoints is introduced by HBASE-16448.
The name of local custom metrics follows the "source.id.metricsName" format, but the name of global custom metrics doesn't follow the "source.metricsName" format.
Ex:

// default metrics
"source.2.shippedOps" : 1234, // peer local
"source.shippedOps" : 12345, // global
// custom metrics
"source.1.failed.start" : 1, // peer local
"failed.start" : 1, // global

When we consider that default metrics do so, it should be "source.metricsName" like:

"source.1.failed.start" : 1,
"source.failed.start" : 1,
