xrestop - monitor server resources used by X11 clients

xrestop --help
xrestop [ --display display ] [ --batch ] [ --delay-time seconds ] [ --max-samples count ]

Xrestop uses the X-Resource extension to provide 'top'-like statistics of each connected X11 client's server-side resource usage. It is intended as a developer tool to aid more efficient server resource usage and debug server-side resource leakage.

Show usage.
Specify X11 display to monitor.
Time in seconds between taking samples. Default is 2 seconds.
Run in batch mode. Slightly more detailed information is streamed to stdout rather than the usual curses interface. This mode is intended for debugging a single client with something like
xrestop -b | grep -A 15 appname
Specify number of times to gather and display results. Default is continuous, which can be set with 0 (zero).

X(7), top(1).

The X-Resource extension is very new and may not be 100% accurate.
