[root at netsaint etc]# du -hs /usr/local/nagios/
94M     /usr/local/nagios

This off course depends on the amount of checks. I have now 222 hosts 
and 590 services.

Log files are not RRD-based, so they grow bigger and bigger (or more 
files, depends on how yo configured it).

[root at netsaint etc]# du -hs /usr/local/nagios/var/
84M     /usr/local/nagios/var

And this is the amount of historical data I have:
[root at netsaint etc]# ls /usr/local/nagios/var/archives/ -hal
total 82M

As you can see, most disk space is taken up by the archives. You can 
safely delete these if you are not interested in historical data.

Nagios is running on an HP LP2000r Netserver dual PIII 1.4 Ghz, 1 Gb 
RAM, 3 NICS (2 100 Mbit, 1 Gbit), 36 Gb RAID 1 SCSI.

Running smoothly by the way (together with some other apps as Veritas 
Netbackup). Check out http://www.nagios.org/userprofiles/browse.php 
for more usage data.

Kind regards,
Tom
