This command runs Unix `ps` command periodically and reports to the user either by email, sms or desktop notification about the process. It can be used for example to monitor length processes. Here at CERN I am working on profiling AliRoot. To get more info on what is AliRoot please go through my previous blog entry.
How it Works
pswatch runs a itz own daemon process (`pswatch.sh`) which periodically checks the existence of the processes in the watch list. The script `psadd.sh` is used to add process on the watch list. `psls.sh` lists the processes on the watch list. `psrm.sh` used to remove a process from the watch list. The process watch lists are maintained as files in the temporary folder. These files store information about each of the process on the watch list in addition to how the process completion has to be notified. The configuration file is $HOME/.pswatchrc
The entire source code can be downloaded from here. Please go through the README file for more detail.
untar the source code and execute the installation script INSTALL
$ tar -xvf pswatch.tar.gz
$ sh INSTALL
The daemon process. To start it run as `nohup pswatch.sh &`. Please note that you cannot add processes on the watch list until the daemon is active. So first step to do is to run the daemon.
$ nohup pswatch &
Add process on the watch list. Use as `psadd.sh 2343 SMS DESKTOP`. 2343 is the PID of the process. After that it can have at max 3 options. SMS, DESKTOP, EMAIL. You need to specify the email address etc on the file $HOME/.pswatchrc
$ psadd.sh 2343 SMS DESKTOP
List process on the watch list. Use as `psls.sh`
Remove process from the watch list. Use as `psrm.sh 2343`.
$ psrm.sh 2343
