Recommendations for monitoring software?


I have a bunch of RHEL servers that nobody monitors for free disk space, if the servers are running out of RAM, all that good stuff. Can anyone suggest something that will monitor this for me automatically, and possible send out emails when a certain threshold is met, like if there's less than 10% disk space on a volume?

A cronjob and script similar to this should work.

This is great monitoring software that takes a little to get setup but it will be your friend when you get it setup.

There are many ways you can do this, the easiest is to write a simple bash script, and cron it to output to a text file and then email to the admin the results.

Commands like du will show diskspace

Code:
cd /
du -hx --max-depth=1
Will show the amount of data on the disk that is being used.

Like I said, the easiest is to use a script, cron it, mail it.

By far the best answer to your question is "pljvaldez" suggestion ... Man that is exactly what you need

I dont think monitoring is really that easy to use, it can be a complex subject but Nagios, Zenoss and Zabbix are all quite easy to use as far as monitoring systems go !

Zenoss is by far the most automated, but might be difficult to work with if you dont get zope or python well, zabbix is built on php, nagios is perl.

Take your pick
