HDD space problems

Hi, I am a newbie user of nagios and I have the next problem:

I have a nagios server to which it has left little hard disc space. I would like to know if it’s possible to delete some folder or file of the nagios (logs or something) to release space without problems.

Regards.

are you sure it’s nagios using up the disc space? what i mean is that usually nagios uses quite little disc space…

I had the same problem yesturday…

i just did du -h from the root folder that will let you know where all your data is… (asuming you have linux?)
then I found out the my /var/log/mysql/ folder was over 5GB I just remove the oldest files
