-#define DESCRIPTION "\
-If the value exceeds the <vwl> threshold, a WARNING status is returned.  If\n\
-the value exceeds the <vcl> threshold, a CRITICAL status is returned.  If\n\
-the data in the log file is older than <expire_minutes> old, a WARNING\n\
-status is returned and a warning message is printed.\n\
-\n\
-This plugin is useful for monitoring MRTG data that does not correspond to\n\
-bandwidth usage.  (Use the check_mrtgtraf plugin for monitoring bandwidth).\n\
-It can be used to monitor any kind of data that MRTG is monitoring - errors,\n\
-packets/sec, etc.  I use MRTG in conjuction with the Novell NLM that allows\n\
-me to track processor utilization, user connections, drive space, etc and\n\
-this plugin works well for monitoring that kind of data as well.\n\
-\n\
-Notes:\n\
-- This plugin only monitors one of the two variables stored in the MRTG log\n\
-  file.  If you want to monitor both values you will have to define two\n\
-  commands with different values for the <variable> argument.  Of course,\n\
-  you can always hack the code to make this plugin work for you...\n\
-- MRTG stands for the Multi Router Traffic Grapher.  It can be downloaded from\n\
-  http://ee-staff.ethz.ch/~oetiker/webtools/mrtg/mrtg.html\n"
