NAME¶

tapset::proc_mem - systemtap proc_mem tapset

DESCRIPTION¶

Process memory query and utility functions provide information about
the memory usage of the current application. These functions provide
information about the full size, resident, shared, code and data used
by the current process. And provide utility functions to query the
page size of the current architecture and create human readable string
representations of bytes and pages used.

proc_mem_size

Total program virtual memory size in pages

See function::proc_mem_size(3stap)
for details.

proc_mem_size_pid

Total program virtual memory size in pages

See function::proc_mem_size_pid(3stap)
for details.

proc_mem_rss

Program resident set size in pages

See function::proc_mem_rss(3stap)
for details.

proc_mem_rss_pid

Program resident set size in pages

See function::proc_mem_rss_pid(3stap)
for details.

proc_mem_shr

Program shared pages (from shared mappings)

See function::proc_mem_shr(3stap)
for details.

proc_mem_shr_pid

Program shared pages (from shared mappings)

See function::proc_mem_shr_pid(3stap)
for details.

proc_mem_txt

Program text (code) size in pages

See function::proc_mem_txt(3stap)
for details.

proc_mem_txt_pid

Program text (code) size in pages

See function::proc_mem_txt_pid(3stap)
for details.

proc_mem_data

Program data size (data + stack) in pages

See function::proc_mem_data(3stap)
for details.

proc_mem_data_pid

Program data size (data + stack) in pages

See function::proc_mem_data_pid(3stap)
for details.

mem_page_size

Number of bytes in a page for this architecture

See function::mem_page_size(3stap)
for details.

bytes_to_string

Human readable string for given bytes

See function::bytes_to_string(3stap)
for details.

pages_to_string

Turns pages into a human readable string

See function::pages_to_string(3stap)
for details.

proc_mem_string

Human readable string of current proc memory usage

See function::proc_mem_string(3stap)
for details.

proc_mem_string_pid

Human readable string of process memory usage

See function::proc_mem_string_pid(3stap)
for details.
