OS-independent auto-monitoring of a program to do things depending on resource usage at runtime
For a caching library, I need to know the runtime usage of memory of the program and the total amount of memory, the total memory used by all the programs etc. I need not do profiling or monitoring but to do different things inside my program depending on memory usage. The search is difficult because all searches go to profiling utilities which I don´t need. Are there some portable way to to this? . The various monitoring libraries indicates that there are ways to do it, but they seem not to allow runtime "internal automonitoring"

you can use the GHC.Stats module, see http://www.haskell.org/ghc/docs/latest/html/libraries/base/GHC-Stats.html, and remember to pass +RTS -T to the program, or -with-rtsopts=-T to the compiler.
