+ *
+ * CHECK_MRTGTRAF.C
+ *
+ * Program: MRTG (Multi-Router Traffic Grapher) traffic plugin for Nagios
+ * License: GPL
+ * Copyright (c) 1999 Ethan Galstad (nagios@nagios.org)
+ *
+ * Last Modified: $Date$
+ *
+ * Command line: CHECK_MRTGTRAF <log_file> <expire_minutes> <AVG|MAX> <iwl> <icl> <owl> <ocl>
+ *
+ * Description:
+ *
+ * This plugin will check the incoming/outgoing transfer rates of a
+ * router, switch, etc recorded in an MRTG log.  If the newest log
+ * entry is older than <expire_minutes>, a WARNING status is returned.
+ * If either the incoming or outgoing rates exceed the <icl> or <ocl>
+ * thresholds (in Bytes/sec), a CRITICAL status results.  If either of
+ * the rates exceed the <iwl> or <owl> thresholds (in Bytes/sec), a
+ * WARNING status results.
+ *
+ * Notes:
+ * - MRTG stands for the Multi Router Traffic Grapher.  It can be
+ *   downloaded from
+ *   http://ee-staff.ethz.ch/~oetiker/webtools/mrtg/mrtg.html
+ * - While MRTG can monitor things other than traffic rates, this
+ *   plugin probably won't work with much else without modification.
+ * - The calculated i/o rates are a little off from what MRTG actually
+ *   reports.  I'm not sure why this is right now, but will look into it
+ *   for future enhancements of this plugin.
