metric is redundant here

we also go with lowercase, so hbase

It may be added so that it does not overwrite other metrics which may overlap or have different type.

for example in HBase you can have already generated metric named Hbase_active: 1.0

Then there is some hbase data with below structure (abbreviated)
...Namespace_test_table_meta_region_abc_metric_get: 20
and which would produce Hbase_active with labels namespace=test,table=meta,region=abc with value 20.0

In that case it would cause metric clash.

I would keep lowercase, as suggested.

labels:
namespace: "$1"
table: "$2"
region: "$3"
value: "$5"
