Thread: A few questions about CPU load and SSH

My main problem with collectl was finding good documentation on your site I had a hard time finding the simplest things like how to install it.

Actually I almost forgot - if you do choose to run sar, don't use the default monitoring interval of 10 minutes - it's pretty useless if you want any meaningful data, though I suspect there are many out there happily SARing away at that level. If I've learned nothing else from collectl it's that data sample coarser than about 10 seconds miss too much key information, such as spikes that tend to get averaged out and...

It might be overkill but something like Nagios (nagios.org) would be able to keep load averages, trends charts, and can alert you as different services reach certain values which you specify.

http://collectl.sourceforge.net/ does both

Wouldn't a simple bash script to be executed in cron suffice? PHP Code: #!/bin/bash load =` cat /proc/loadavg|awk  { ' print  $ 1 ' }` date =` date ` disp = $date . $load echo  $disp | tee  - a loadavg . txt 

Hello, If you want to collect loadavarage history of your server. Then I would recommend 'sar' tool. If you want to collect traffic history then you can use 'vnstat'. Both are handy gpl tools in order to keep good load and traffic track of your server.
