It's not clear what "samplerName" refers to.
Is it the JMeter sample results - i.e. the filtering - or is it the
attribute of the metrics data?
And where is the default defined?
How does one change it?

Two dots?
Really?

If the code appends a dot to the prefix, why does the default prefix
end with a dot?
Or was that a mistake?

5) Also, how does

<rootMetricsPrefix>.<samplerName>.a.count
   Number of responses for sampler name

differ from

<rootMetricsPrefix>.<samplerName>.ok.count
  Number of successful responses for sampler name

and

<rootMetricsPrefix>.<samplerName>.ko.count
  Number of failed responses for sampler name

It's not clear what the 'a' means in 'a.count'
