3 * CHECK_VSZ.C
4 *
5 * Program: Process plugin for Nagios
6 * License: GPL
7 * Copyright (c) 1999,2000 Karl DeBisschop <kdebiss@alum.mit.edu>

11 * Description:
12 *
13 * This plugin will check for processes whose total image size exceeds
14 * the warning or critical thresholds given on the command line. With
15 * no command_name, everything that shows up on ps is evaluated.
16 * Otherwise, only jobs with the command_name given are examined.
17 * This program is particularly useful if you have to run a piece of
18 * commercial software that has a memory leak. With it you can shut
19 * down and restart the processes whenever the program threatens to
20 * take over your system.
21 *
22 * Modifications:
23 *
24 * 11-18-1999 Karl DeBisschop (kdebiss@alum.mit.edu)
25 * change to getopt, use print_help
26 * 08-18-1999 Ethan Galstad (nagios@nagios.org)
27 * Changed code to use common include file
28 * Changed fclose() to pclose()
29 * 09-09-1999 Ethan Galstad (nagios@nagios.org)
30 * Changed popen()/pclose() to spopen()/spclose()
31 * 11-18-1999 Karl DeBisschop (kdebiss@alum.mit.edu)
32 * set STATE_WARNING of stderr written or nonzero status returned
