	IOWait is a CPU metric, measuring the percent of time the CPU is idle, but waiting for an I/O to complete. Hello everyone. Sometimes we need to find CPU related information in a Linux system, such as CPU vendor, number of CPU cores, number of threads, CPU clock speed, available CPU cache and many more. In NMON also CPU01,T0067,1. We have 32 CPU Cores and they all just show as Average CPU Load , each with a different color but not a CPU number associated. Unlike bandwidth, monitoring CPU utilization is much more straightforward. The Itanium (IA64) processor is not supported. In this guide, we will narrow down to the CPU/processor, and show you various ways of extracting detailed information about your machine CPU. You can also fetch details of each cpu cores using top command console. So today we shall be checking the commands that can be used to check memory usage on a linux system. How To: Network / TCP / UDP Tuning This is a very basic step by step description of how to improve the performance networking (TCP & UDP) on Linux 2.
