prmon | Standalone monitor for process resource consumption

prmon is a C++ library. prmon has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The PRocess MONitor is a small stand alone program that can monitor the resource consumption of a process and its children. This is useful in the context of the WLCG/HSF working group to evaluate the costs and performance of HEP workflows in WLCG. In a previous incarnation (MemoryMonitor) it has been used by ATLAS for sometime to gather data on resource consumption by production jobs. One of its most useful features is to use smaps to correctly calculate the Proportional Set Size in the group of processes monitored, which is a much better indication of the true memory consumption of a group of processes where children share many pages. prmon currently runs on Linux machines as it requires access to the /proc interface to process statistics.
