This Support Knowledgebase provides a valuable tool for SUSE customers and parties interested in our products and solutions to acquire information, ideas and learn from one another. ![]() There may be problems with these applications as well that may require further debugging or troubleshooting. ![]() The task’s share of the elapsed CPU time since the last screen update, expressed as a percentage of total CPU time. Fig.01: top command in action (click to enlarge) You can see Linux CPU utilization under CPU statistics. You might consider moving one of those processes to another server. Top command to check Linux CPU usage or utilization. In this case the third party vbatch and emconfig commands are taking up most of the CPU cycles. # ps axwwo %cpu,pid,user,cmd | sort -k 1 -r -n | head -11 | sed -e '/^%/d' ![]() Supportconfig uses the following command to capture the Top 10 CPU Processes: You can find which applications are consuming the most CPU cycles by looking in the supportconfig basic-health-check.txt file under the Top 10 CPU Processes section or using the ps command. However, if you are experiencing low memory and high CPU utilization, you may have an overburdened server. If your server seems to run properly, then the high CPU utilization may just be a spike in activity and can just be monitored. If you observe noticeable performance problems, they you need to investigate further. If you are looking for other articles which is related to memory then navigate to the following link. In this method, we are using combination of top, print and awk command to get the CPU utilization percentage. ![]() However, it is an indication performance may be suffering. Method-1: How to check CPU utilization percentage in Linux We can use the following combination of commands to get this done. top command (should use): The task's share of the elapsed CPU time since the last screen update, expressed as a percentage of total CPU time. It's not necessarily a bad thing to have high CPU utilization on a Linux server. CPU usage is currently expressed as the percentage of time spent running during the entire lifetime of a process. ![]()
