-This plugin will check either the average or maximum value of one of the\n\
-two variables recorded in an MRTG log file.\n"
-
-/* old command line:
- <log_file> <expire_minutes> <AVG|MAX> <variable> <vwl> <vcl> <label> [units] */
-#define OPTIONS "\
--F log_file -a <AVG | MAX> -v variable -w warning -c critical\n\
- [-l label] [-u units] [-e expire_minutes] [-t timeout] [-v]"
-
-#define LONGOPTIONS "\
- -F, --logfile=FILE\n\
- The MRTG log file containing the data you want to monitor\n\
- -e, --expires=MINUTES\n\
- Minutes before MRTG data is considered to be too old\n\
- -a, --aggregation=AVG|MAX\n\
- Should we check average or maximum values?\n\

- Which variable set should we inspect? 1 or 2?\n\
- -w, --warning=INTEGER\n\
- Threshold value for data to result in WARNING status\n\
- -c, --critical=INTEGER\n\
- Threshold value for data to result in CRITICAL status\n\
- -l, --label=STRING\n\
- Type label for data (Examples: Conns, \"Processor Load\", In, Out)\n\
- -u, --units=STRING\n\
- Option units label for data (Example: Packets/Sec, Errors/Sec, \n\
- \"Bytes Per Second\", \"%% Utilization\")\n\
- -h, --help\n\
- Print detailed help screen\n\
- -V, --version\n\

-
-#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"
