Change subject: Add *_delta stats for vhtcpd ganglia.
......................................................................
Add *_delta stats for vhtcpd ganglia.
Augment vhtcpd data collected by ganglia with "delta" metrics which record the
difference between the current sample and the prior sample. This should help
make spotting the time rate of change differences easier for human eyes.
- increase gmond script internal cache time to 30s.
- add inpkts_recvd_delta, inpkts_sane_delta, inpkts_enqueued_delta,
inpkts_dequeued_delta, queue_overflows_delta, & queue_max_size_delta stats.
