Distributed SNMP monitoring.

I probably ought to do a lot more research before I continue to speak, but I
don't mind being corrected in public one bit, so... :-)

I certainly agree.

Bad use of made-up terminology on my part - by "an rrdtool process" I was
actually refering to apan itself, which gets a process creation every time
Nagios uses it to check on a host or service.  Apan then runs the plugin on
behalf of Nagios, so you end up with two processes created per check instead
of one...correct?  Again, I ought to do more research first...but my
impression from the apan docs is that it doesn't keep running as a daemon in
the background, but rather has to open and close the rrd files every time an
apan service or host gets checked.
 
An alternative would be a process that holds open the
xpdfile_host_perfdata_file and xpdfile_service_perfdata_file and then
updates the rrd files when it sees new performance data in either file.
