ConFoo Montreal is a multi-technology conference for developers. This year , they have conducted the program to exchange knowledge and ideas from speakers all over the world. Our Architect Ram Lakshmanan was invited to give a talk on the topic: "Let's crash the applications!" In this session, following topics have been discussed: code snippets that... Continue Reading →

What is ‘Load Average’?

Load average is an age-old metric, which is in existence since the 1970s to indicate whether the system is under heavy/average/low load. It is useful to indicate whether the system’s load is on an increasing trend or a decreasing trend. In this article, let’s learn more about ‘Load Average’. How to understand 'Load Average'?  In...

I/O waiting CPU time – ‘wa’ in top

CPU consumption in Unix/Linux operating systems are studied using 8 different metrics: User CPU time, System CPU time, nice CPU time, Idle CPU time, Waiting CPU time, Hardware Interrupt CPU time, Software Interrupt CPU time, Stolen CPU time. In this article let us study about ‘waiting CPU time’. What is ‘waiting’ CPU time? Waiting CPU... Continue Reading →
