[hobbit] monitor a series of files for absolute size (alert & trending)

[Hubbard, Greg L]

you can probably write a custom script that will do what is needed, and
have the Hobbit client run it wherever you need it.  Then you can write
another script on the server side to "catch" the data and set up the RRD
calls.  There are several moving parts, but Henrik has done a nice job
explaining what needs to be done, and provides a helpful example.
 
I use this function for a number of custom measurements, and it ticks
like a watch.  Took me a few hours to get the first one working, and the
rest were pretty easy after that.

	greetings,
	
	I need to monitor some os and db backup files for their sizes
for alert based on absolute sizes as well as rrd trending. Does Hobbit
do this now? I am running 4.2-RC-20060712 on CentOS 4.3/i386.
	
	A twist is the file names are timestamped
(os-backup-YYYYMMDD-HHmm.star.gz).  any suggestions/tricks? I thought of
making a copy to a fixed name for monitoring, but it is kinda expensive
due to the size of the backups themselves.
