.TH MEMUSAGESTAT 1 2019-03-06 "GNU" "Linux programmer's manual"
|
|
.SH NAME
|
|
memusagestat \- generate graphic from memory profiling data
|
|
.SH SYNOPSIS
|
|
.BR memusagestat " [\fIoption\fR]... \fIdatafile\fR [\fIoutfile\fR]"
|
|
.SH DESCRIPTION
|
|
.B memusagestat
|
|
creates a PNG file containing a graphical representation of the
|
|
memory profiling data in the file
|
|
.IR datafile ;
|
|
that file is generated via the
|
|
.I -d
|
|
(or
|
|
.IR --data )
|
|
option of
|
|
.BR memusage (1).
|
|
.PP
|
|
The red line in the graph shows the heap usage (allocated memory)
|
|
and the green line shows the stack usage.
|
|
The x-scale is either the number of memory-handling function calls or
|
|
(if the
|
|
.I -t
|
|
option is specified)
|
|
time.
