To use mpstat, first install the sysstat package using your distribution's package manager. The mpstat command is another tool that can be used to measure CPU usage on a per-core basis. Measure CPU Core Usage using mpstat Command For example, the first core is using 0.3% of the CPU, while the other cores are not being used at all. In the above output, the %CPU column shows the CPU usage for each core. Tasks : 23 total, 1 running, 22 sleeping, 0 stopped, 0 zombie This will display a breakdown of the CPU usage for each core, as well as the overall usage. To do this, first, run the top command and press 1 to see the usage of each CPU core. By default, top displays the overall CPU usage for all cores, but it also provides a way to see the CPU usage for each core individually. The top command is a commonly used tool for monitoring system resources, including CPU usage. In this article, we will see how to measure separate CPU core usage for a process on Linux using various command line tools. This can be helpful for identifying bottlenecks in the system, or for understanding the workload distribution across CPU cores. On modern multi-core CPUs, it is often useful to know the CPU usage of individual cores for a particular process.
