Therefore, we need to extract the timestamp and the CPU usage from this output. We’ve terminated the top command by pressing Ctrl-C after four iterations.Īccording to this problem, we only need the CPU usage data. This procedure activates perf top and profiles CPU usage in real time. Top - 21:26:45 up 1 day, 12:05, 1 user, load average: 1.43, 1.36, 1.34ġ85292 kent 20 0 3077452 284916 82880 S 53.5 0.9 2:01.54 mpvĪs the output above shows, the top command prints the process status every two seconds. In its default state, perf top tells you about functions being used across all CPUs in both the user-space and the kernel-space. Here’s a placeholder command you can copy and adjust as per your requirements (switch out the integers with your settings): gpmonit openlitespeed -cpu-warning-percent 100 -cpu-warning-cycles 5.

Tasks: 1 total, 0 running, 1 sleeping, 0 stopped, 0 zombie At first, the CPU-related statistics (the us, sy, and id fields). Using the top Command to Print the Status of a Single Process in Batch Modeįor example, we can make the top command keep reporting the status of the mpv process every two seconds until we manually kill it: $ top -b -d 2 -p $(pidof mpv) Here we have used the command vmstat 1 10 to sample the system every second for ten times. on servers, embedded systems using nix, etc. For instance, I use it to monitor apache2, mysql, proprietary services, applications, etc. The monit tool is generally used for monitoring services on a machine and restart them when necessary. ![]() Then, we can monitor the changes of the log file using the tail -f command: $ tail -f /tmp/log_ps.txtįri Sep 3 10:05:08 PM CEST 2021 :: mpv 40.9%įri Sep 3 10:05:10 PM CEST 2021 :: mpv 40.9%įri Sep 3 10:05:12 PM CEST 2021 :: mpv 41.0%įri Sep 3 10:05:14 PM CEST 2021 :: mpv 41.1%įri Sep 3 10:05:16 PM CEST 2021 :: mpv 41.2%įri Sep 3 10:05:18 PM CEST 2021 :: mpv 41.2%Īs the output shows, our script has written CPU usages of the mpv process to the specified log file every two seconds. This is still work in progress, but I prefer continuing the discussion here rather than on a git issue. Therefore, when we start the script, it’ll keep writing CPU usage of the given process to the log file until we terminate it manually.Īlso, we write the current time “ $(date)”, process name and PID “ $PNAME” together with the CPU usage data to the log file.
