FOOTPRINT(1) BSD General Commands Manual FOOTPRINT(1)NAME
footprint -- gathers memory information about one or more processes
SYNOPSIS
footprint [-j path] [-f bytes|formatted|pages] [-p name|pid] [-x name|pid] [-t] [-s] [-v] [-y] [-w] [--swapped] [--wired] [-a] process-name |
pid | memgraph [...]
footprint -h, --help
DESCRIPTION
The footprint utility gathers and displays memory consumption information for the specified processes or memory graph files.
footprint will display all addressable memory used by the specified processes, but it emphasizes memory considered 'dirty' by the kernel for
purposes of accounting. If multiple processes are specified, footprint will de-duplicate multiply mapped objects and will display shared
objects separately from private ones.
footprint must be run as root when inspecting processes that are not owned by the current user.
OPTIONS -a, --all
target all processes (will take much longer)
-j, --json path
also save a JSON representation of the data to the specified path
-f, --format bytes|formatted|pages
textual output should be formatted in bytes, pages, or human-readable formatted (default)
-p, --proc name
target the given process by name (can be used multiple times)
-p, --pid pid
target the given process by pid (can be used multiple times)
-x, --exclude name/pid
exclude the given process by name or pid (can be used multiple times)
often used with --all to exclude some processes from analysis
-t, --targetChildren
in addition to the supplied processes, target their children, grandchildren, etc.
-s, --skip
skip processes that are dirty tracked and have no outstanding XPC transactions (i.e., are "clean")
-v display vmmap-like output of address space layout
-y, --summary
print only regions with dirty memory, and condense __TEXT, __DATA, and __LINKEDIT regions into 'Other' subtotal
-w, --wide
show wide output with all columns (implies --swapped --wired)
--swapped
show swapped/compressed column, a subset of 'dirty'
--wired
show wired memory column, a subset of 'dirty'
-h, --help
display help and exit
