Hi,
I want to monitor my Linux servers using NRPE.

Based on the info from a typical server can be seen below. What should I monitor?

Should I run separate check for:
/
/opt
/usr

Or is it enough with just running a check for:
/

Any comments what is important to consider before deciding how the partions/discs should be monitored is welcomed!

Best Regards
R.

Personally we monitor all the partitions except for mount points and cdrom drives... there really isn't a black and white right or wrong answer. Work out what partitions if they fill is going to a. Break applications and b. Stop users from doing work. So to that effect you are probably going to want to ensure that the partitions with /home, /var, /opt, /usr and maybe /tmp are covered.
