How To Monitor A System With Sysstat On Centos 4.3

Post date: August 29, 2006, 15:08 Category: System Views: 6206 Comments
Tutorial quote: A common task for System Administrators is to monitor and care for a server. That's fairly easy to do at a moment's notice, but how to keep a record of this information over time? One way to monitor your server is to use the Sysstat package.

Sysstat is actually a collection of utilities designed to collect information about the performance of a linux installation, and record them over time.

It's fairly easy to install too, since it is included as a package on many distributions.

Change Ctrl + Alt + Delete Behavior To Open System Monitor, in Linux

Post date: September 24, 2009, 12:09 Category: Miscellaneous Views: 2093 Comments
Tutorial quote: Actually, I've written this post before (quite a few months ago) but then deleted it because it didn't work. In the mean time, I found out why, so I decided to post it again. I find pressing Control + Alt + Delete to open up System Monitor to be very useful, especially for Windows users who are used to it and may actually press this quite a few times before realizing it doesn't do anything or what it does in Windows. Using System Monitor, you can preview all running processes, end or kill them, see how much CPU a process is using, CPU + memory + network history, available disk space and even change how much CPU a process should use.

There are 2 ways of changing Ctrl + Alt + Delete behavior to open System Monitor: one if you are running Compiz, and one for Metacity, only to use if you are not running Compiz.

Custom Monitoring MySQL and SNMP with BixData

Post date: February 3, 2007, 00:02 Category: Software Views: 3226 Comments
Tutorial quote: With BixData you can monitor your servers as well as VMware and Xen. BixData includes pre-built plugins for things like CPU, Memory, Disk, etc. but any good monitoring tool needs to be customizable. BixData includes the basic ability to run scripts and record their exit values, similar to Nagios Plugins. BixData 2.7 adds support for importing data in more complex formats. This allows you to monitor almost anything. I'll go through the steps showing you how to monitor MySQL locally where an agent is installed and then the steps to monitor a device remotely through SNMP. The advantage of BixData is that any data available through a BixAgent works with the standard tools such as the situation room, scoreboards, notifications and the reporting system. All data are stored in standard SQL tables and are easily accessible.
