Different results while profiling memory to get max RSS with massif and time

A little bit of the context: I try to implement a C++ application that uses mmap to map some arbitrary large files for reading and writing, which can scale from a few MB to several GB. Due to this, it is important to profile the memory usage (peak…

How do I find why the virtual memory foot print continuously grows with this daemon?

I created a daemon which I use as a proxy to the Cassandra database. I call it snapdbproxy as it proxies my CQL commands from my other servers and tools. Whenever I access that tool, it creates a new thread, manages various CQL commands, and then I…

massif reported heap usage much less than VmRss, what could be wrong?

massif output: time=3220706 mem_heap_B=393242041 mem_heap_extra_B=73912175 mem_stacks_B=93616 heap_tree=peak process shows 1.2GB in VmRss, so the huge difference comes from where? (I saw Rss grows up continuously).

Can massif measure global/static data cost?

I see massif can measure heap use, and also stack use with some options. Does it also report global data consumption (the data defined as global or static variables)?

I have a program. When it runs normally, my hard-coded peak memory checker reports 1G. When it runs with massif, my checker reports 2.2G... My peak memory checker is not a smart checker, I only call it at hard-coded place to get the current memory…
