8. Server Tools and Techniques Using ps command effectivelyUsing ps command effectively ps -efwH | grep avnpython Organizes parent/child processes Approximates thread structure Avnkill commandAvnkill command Stops all avnpython processes on host. Using kill can be awkward. AvninitAvninit Persistent process. Starts servers in correct order on correct hosts. Detects and restarts failed servers.
