- *
- * Program: Current users plugin for Nagios
- * License: GPL
- * Copyright (c) 1999 Ethan Galstad (nagios@nagios.org)

- * Last Modified: $Date$
- * Modifications:
- *
- * 1999-11-17 Karl DeBisschop
- * - check stderr and status from spoen/spclose
- * - reformat commenst to fit 80-cahr screen
- * - set default result to STATE_UNKNOWN
- * - initialize users at -1, eliminate 'found' variable
- *
- * Command line: CHECK_USERS <wusers> <cusers>
- *
- * Description:
- *
- * This plugin will use the /usr/bin/who command to check the number
- * of users currently logged into the system. If number of logged in
- * user exceeds the number specified by the <cusers> option, a
- * STATE_CRITICAL is return. It it exceeds <wusers>, a STATE_WARNING
- * is returned. Errors reading the output from the who command result
- * in a STATE_UNKNOWN error.
