memory usage reporting tool This provides a collection of memory usage monitoring tools and scripts. - Mallinfo library outputs values from the Glibc mallinfo() function, either with SIGUSR1 like libleaks, or at given intervals. I.e. it tells how much allocated and freed (but not returned to system) memory is in the C-library memory pool for the process. You can use this to detect memory fragmentation. - mem-*monitor* tools output system and process memory (and CPU) usage overviews at specified intervals. - There are also some extra scripts to get memory usage details from processes. Manual pages tell more about the tools and scripts.
