Best way to monitor disk usage?

[junglecom]

I have some linux/windows servers and SANs where I would like to send an alert if used storage reaches a certain percentage.
What is the best tool I can use for this and how do I install/configure it?

I still do not understand what the process is to install plugins in nagios core 3.4.3.

Thank you all for your assistance

On the note of plugins please see the following from our installation guide:

wget http://prdownloads.sourceforge.net/sour ... .16.tar.gz

6) Compile and Install the Nagios Plugins

Extract the Nagios plugins source code tarball.


cd ~/downloads

tar xzf nagios-plugins-1.4.16.tar.gz

cd nagios-plugins-1.4.16

Compile and install the plugins.


./configure --with-nagios-user=nagios --with-nagios-group=nagios

make

make install

As far as monitoring disk usage, the easiest way in my opinion to set that up would be through NRPE active checks.. this guide will show you how to install the NRPE agent "NSClient++" on the windows system and also shows an example of monitoring disk usage:

What would the process be to install a single 3rd-party plugin? Install instructions are never included on the Nagios Exchange posts.

Ive seen NRPE, But is there another way without having to configure the host or installing an agent? for both windows and linux?

thank you again!

Check out these documents for the procedure: http://library.nagios.com/library/produ ... e/manuals/

You could use snmp, but that would also involve setting it up on the client. NRPE is probably your best route.

I managed to figure out the SNMP way. Looks like its working good. Was tricky to find the OID for each drive.

Thank you for all your help!
