Description Lê Hoàng Phương 2021-04-19 02:28:30 UTC 
SUMMARY
plasma-systemmonitor currently only shows the memory usage of the pycharm.sh script, which is a shell script that starts the actual JVM and loads Pycharm in a subprocess.

STEPS TO REPRODUCE
1. Open Pycharm
2. Open plasma system monitor
3. 

OBSERVED RESULT
System monitor shows memory usage of only the shell script.

EXPECTED RESULT
System monitor shows memory usage of the whole Pycharm's process tree.

SOFTWARE/OS VERSIONS
Operating System: KDE neon 5.21
KDE Plasma Version: 5.21.4
KDE Frameworks Version: 5.81.0
Qt Version: 5.15.2
Kernel Version: 5.8.0-50-generic
OS Type: 64-bit

ADDITIONAL INFORMATION

The script does not use "exec" to replace the script process with the JVM process. If  I manually edit the script to use "exec", then system monitor will show the memory usage correctly.
