Monitoring CPU Load Averages with Shell Script
Today I started re-inventing myself, started looking what all I did for me and my team to perform in better ways. Remembered those we used to open UNIX SSH windows to monitor How the CPU load average in each site. While doing this monitoring activity on site1, there might be possible that some other site reach to overload, which leads to uncontrol tendency to work. It was funny, my dear buddy named it as 'Barbar work!!' :) After little R & D on Google/Internet found few suitable solutions. I had chosen 'uptime' command running with remote SSH connection in a loop. Adding more value to this sending a mail on the event of crossing the threshold value. This threshold will be vary depending upon the application and CPU power. Trail and error make you to identify what could be the threshold. Defining these threshold values Venu GopalRao helped a lot. Once script started working he was amazed and appreciated as well. This script can be run forever with a specified ti...
