Typo in $graphite->send()

[vmdude]

The $graphite->send() path parameter should not have trailing dot as it's added by default

For instance instead of

$graphite->send(path => "vi.", data => $vcenter_exec_duration_h)

We should use

$graphite->send(path => "vi", data => $vcenter_exec_duration_h)

If not, when enabling graphite trace, we see
