Please let me know if you need further information. What can we do to improve the CPU utilization of that VM? Also check that the necessary debug symbols are available to the Performance Analyzer, either at a standard location ( /usr/lib/debug or next to the binaries). Up to date version of VMware tools installed Learn how to monitor CPU load with common commands, the impact of high CPU. Ubuntu 12.04.4 LTS (GNU/Linux 3.8.0-36-generic x86_64) Monitoring CPU utilization and CPU load is essential for optimizing performance. Here are some specs about the environment and the VM: To exit the top command, press the Ctrl+C keys. You can press Shift+M to sort it by memory. The vCenter statistics does show a spike on the CPU load, but the spike only climbs up and stays in between 25 and 50 percent or a maximal usage of 7,309 MHz (out of 16,000). Just run the command in the terminal: top By default, the top command output is sorted by CPU consumption. The return of the vmstat 1 command during that time is: Even though there’s a lot of workload on that system, the VM only seems to utilize about 25 % till 50 % of its CPU capacity. This will display all processes currently running in your system. The VM has 8 vCPU’s (switched from 2 sockets with 4 cores to 8 sockets with one core) and the latest VMware tools installed. A much more handy and straightforward approach on system monitoring is to simply open a terminal, type top and hit enter. We’re experiencing the following problem with an Ubuntu VM:
