Help Support Ethan

A Message From The Founder...

As the founder of Nagios, I'm asking for your help in a cause that's dear to my heart.

I'm launching a new project to help better the world by providing the information, ideas, and inspiration that I believe can improve the lives of people everywhere.

I know you're busy managing networks, but I would appreciate it if you would consider liking my Facebook page and showing your support for the content and messages I produce by sharing them with your friends and family.

You can learn more about my project by visiting ethangalstad.me/nagios. Thank you for your time. I wish you all the best in your endeavors, whatever they may be.

Nagios plugin to check the overall health of a system. Uses SSH to connect to remote server,
requires that passwordless login is enabled (SSH Key authentication).
Checks the following:
- 15 minute load (warning or critical)
- Swap useage (warning or critical)
- All locally mounted partitions useage % (warning or critical)
- RAM useage % (warn only)
- CPU useage % (just a "nice to know", no warnings)

Tested on Ubuntu 11.10, 10.04 and Debian 6 running Python 2.7.2+

Note: if you're getting an error about unable to change to float, your hostname may be wrong.

Example command definition:

# system_check command, see /usr/lib/nagios/plugins/system_check
# for more information.
define command {
command_name system_check
command_line /usr/lib/nagios/plugins/system_check -H $HOSTADDRESS$ -U $ARG1$ -l $ARG2$ -L $ARG3$ -d $ARG4$ -D $ARG5$ -r $ARG6$ -s $ARG7$ -S $ARG8$
