LMDBG-STAT(1) LMDBG-STAT(1) NAME lmdbg-stat - outputs statistical information based on lmdbg-run output SYNOPSIS lmdbg-stat [OPTIONS] [files...] DESCRIPTION lmdbg-stat takes output of lmdbg-run or other lmdbg-* utilities on input and outputs total and per-stacktrace statistical information about memory allocations. The following statistics is output: allocs or total_allocs Per-stacktrace or total number of memory allocations max or total_max Per-stacktrace or total maximum of requested bytes peak or total_peak Per-stacktrace or total peak of allocated memory leaks or total_leaks Per-stacktrace or total amount of bytes that were allocated but not freed OPTIONS -h Display the help message. -V Display the lmdbg version.
