Linux monitoring offers several options to monitor your process. The first option is to use GnuDB (debugger). GnuDB is an open source and widely available debugger you can instruct to inform beSTORM whenever an exception occurs. A sample script that preforms this is located in the beSTORM installation folder (gdb_monitor.pl).
In some cases, debugging is not possible as the process can spawn new child processes, is a kernel module, etc. In those cases, you can use a non-debugger beSTORM monitor agent.
For example, the bestorm_tail.pl script (included with beSTORM) follows a provided file and looks for specific strings. It will then pass the strings to beSTORM to report that some failure/exception has occurred. If the more common SEGFAULT string is found inside a program's log file, this indicates that a segmentation fault (a crash, usually unhandled) has occurred.
