It means high “steal time” and it applies only to virtual machines.In such situations, our experts generally look for and fix high disk I/O.The CPU is waiting for the result of some I/O operation and it is not doing anything else in the mean time.So the first step is to identify any resource responsible for the issue.įor e.g., If with high CPU utilization, we have : a) High %wa We have seen that issues with RAM, Disk etc. Resources that may cause high CPU utilizationĬPU alone may not be responsible for the utilization problem. %Cpu(s): 16.8 us, 1.5 sy, 0.0 ni, 81.1 id, 0.5 wa, 0.0 hi, 0.1 si, 0.0 stĪs we shall see here, these numbers help us identify the probable causes for the high CPU utilization.ġ. A sample output for the top looks like this : ![]() They more or less guide us to where the problem lies.Ī commonly used command for this is top. To troubleshoot this utilization issue, we first analyze the CPU statistics. High traffic – When faced with a high traffic, a system will run out of resources.Bug in the code – An application bug can lead to memory leak etc.System configuration – Certain default settings or other misconfigurations can lead to utilization issues.Resource issue – Any of the system resources like RAM, Disk, Apache etc.So today, let’s see how we troubleshoot high CPU utilization in Linux servers. That’s why at Bobcares, we prevent downtime by monitoring and resolving such utilization issues as quickly as they come. ![]() ![]() ![]() It results in sluggish servers, unresponsive application and unhappy customers. At one time or another every server owner faces high CPU utilization or CPU running at 100%.
