A *real* simple solution that would give you the very basic information about a system would be PHPSysAdmin.<br><br><div class="gmail_quote">On Fri, May 13, 2011 at 9:23 PM, JD <span dir="ltr"><<a href="mailto:jdp@algoloma.com">jdp@algoloma.com</a>></span> wrote:<br>

</div>For 2 boxes, it would be hard to justify the effort for Nagios. I'd do<br>
something really easy like SysUsage. <a href="http://sysusage.darold.net/" target="_blank">http://sysusage.darold.net/</a> You<br>
could deploy this in under 5 minutes.<br>
<br>
<br>
Anyway, go grab a copy of the source tgz and follow along.<br>
<br>
tar zxvf SysUsage-Sar-3.0.tar.gz<br>
cd Sys*0<br>
sudo apt-get install sysstat rrdtool librrds-perl<br>
perl Makefile.PL<br>
make<br>
sudo make install<br>
sudo crontab -e<br>
<br>
Drop these lines into the root crontab.<br>
<br>
<br>
<br>
*/1 * * * * /usr/local/sysusage/bin/sysusage > /dev/null 2>&1<br>
<br>
*/5 * * * * /usr/local/sysusage/bin/sysusagegraph > /dev/null 2>&1<br>
<br>
I performed these steps using Cluster SSH on almost all our Ubuntu<br>
8.04.x servers; each installation worked.<br>
