Point at the Mbean ServerInfo under the domain jboss.system. If you want to inspect jBoss Thread CPU’s usage you have a shortcut from the jmx-console. Within that folder, you can run operations such as get ThreadCpuTime(Thread) to gather information for a particular thread: Now from the MBeans Tab select the folder: Start the JConsole shell bundled in WildFly: $ bin/jconsole.sh JBoss EAP and WildFly users can use JConsole in order to monitor the usage of the application server. Monitoring WildFly CPU usage with JConsole 4.3.Here is a screenshot of the Profiler tab showing CPU profiling results: 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. Tasks: 1 total, 0 running, 1 sleeping, 0 stopped, 0 zombie 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) 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.
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.
We put the logging implementation in a “ while true…“.
