Notes:\n\
- This plugin requres that the MRTGEXT.NLM file from James Drews' MRTG\n\
  extension for NetWare be loaded on the Novell servers you wish to check.\n\
  (available from http://www.engr.wisc.edu/~drews/mrtg/)\n\
- Values for critical thresholds should be lower than warning thresholds\n\
  when the following variables are checked: VPF, VKF, LTCH, CBUFF, and LRUM.\n"
