SYNOPSIS
pagemon [options]
DESCRIPTION
pagemon is a program that allows one to interactively monitor the memory pages of a process.
OPTIONS
pagemon options are as follow:- -a
- enable automatic zoom mode, this will change the zoom level to show the entire page map in the window, up to a maximum zoom level of 999.
- -d delay
- delay in microseconds between data refreshes, the default is 10,000 microseconds (1/100th of a second).
- -h
- show help.
- -p
- specify the process id (PID) or name of the process to monitor. If a name is given, then pagemon will monitor the first process that matches the name.
- -r
- read pages into memory. This will force all pages in the process to be read into physical memory.
- -t ticks
- specify ticks between dirty page checks. The default is 60 ticks; the larger the value the longer time between dirty page checks.
- -v
- enable VM information view. This is equivalent to pressing the 'v' or 'V' key when running pagemon.
- -z zoom
- specify the default zoom level on page view, the default is 1 (that is 1-to-1 view of pages). Higher values increase the zoom level so more pages are represented in the map view.
