Description

DMP is a extension of the heap-profiler of tcmalloc. It records resident memory sizes of each allocations using /proc/self/pagemap and dumps logs at constant interval. Dumped logs can be processed by dmprof to classify each allocation to one of the components defined in a policy file. File discriptions: dmprof: a python script for analyzing logs policy: a setting file used by dmprof gmail-send-self-test: a shell script for running a gmail test BUG= TEST=
