RE: {bb} Missing chunks of larrd graph data

["Chan, Jason" <J.Chan@ixiscm.com>]

Umm. I was thinking it was related to backup traffic which might jammed
up the network.  But no.  Normally, network backup traffic might affect
just a couple of slow interface servers, but not all.  Also, it just
happens that we got quite a lot of BB alerts during that window.  So we
know BB was receiving data from all the servers, but they are just not
being reflected in the larrd graphs.  Very strange.

This usually indicates that no status messages were received during
that time - e.g. the machine was down, the client was stopped, or
your network was jammed with backups so the data didn't get through.

The "larrd.pl" script runs as a BB server extension every 5 minutes
(usually off the bb-bbexttab file). It picks through the status logs
and updates the RRD files with the data it finds.
