SUMMARY
Often there are multiple processes with the same name running on the system, which actually are completely different programs. This is common e.g. with interpreted/virtualized languages such as Python or Java. The program that is actually running can be usually determined by looking at process command line (e.g. finding a script file name).

System monitor can display processes' command lines, but it lacks the ability to quickly find such processes by typing part of command line (e.g. script name) in search field. This is possible in ksysguard, but not in System monitor.
