A simple program that monitors real memory usage of processes. For example, I have multiple processes, all of them are named similarly. In my case, I use a common prefix as a command-line argument. The program will monitor up to 30 different processes; the max value is defined in monitor.c. I have a few game servers that all share "iw5" as the name prefix. I would start this program with ./monitor iw5 to monitor the memory usage of all my game servers. In my case, each process should not exceed more than 1 GiB of real memory, again, the max value is defined in monitor.c. If that's the case, a memory leak has occurred, and this program will send a request to terminate that process gracefully (SIGTERM). SIGTERM usually works for me. I have in place a separate system to automatically restart my game servers. I hope this program can be useful to others.

How to?

Compile from source using the provided makefile. Execute the program like this: ./monitor <NAME OF PROGRAM>
