memgraphinator

I want a tool to draw the memory usage graph of a given process over time. I want to see memory leaks.

I couldn't find one so I started writing my own.

Usage

./memgraphinator.py [--exit-when-process-dies]
./memgraphinator.py [--exit-when-process-dies] [-p|--pid] PID ...
./memgraphinator.py [--exit-when-process-dies] [--] command [args ...]
./memgraphinator.py -h|--help

positional arguments:

command [args] Command to execute and monitor

optional arguments:

-h, --help	Show this help message and exit
-p PID, --pid PID
	Specify existing process to monitor
--exit-when-process-dies
	Exit when monitored process dies

Requirements

• Linux (for /proc/{pid}/status)
• Python
• PyGObject with GIR libraries for GTK etc.

Note

On Ubuntu be sure to apt-get install python3-gi python3-gi-cairo gir1.2-gtk-3

• A reasonably new GTK+ (3.10 is fine but 3.12 is preferred)

Future plans

• Accurate time axis (when you suspend laptop, graph stops, but this is not reflected in "N seconds ago" messages)
• Export graph to CSV
