Re: (usr-tc) Span Level monitoring via Cricket

      Almost forgot, here is a set of Defaults and some example targets.

  hiperget        =    "%hipergetprog% %hostname% %snmp-community% %card% %span%"
  target-type     =    HiPerARC
  snmp-community  =    "public"

datasource      --default--
  rrd-ds-type             =       GAUGE
  rrd-heartbeat           =       1800
  rrd-min                 =       undef
  rrd-max                 =       undef

datasource  portsinuse  ds-source = EXEC:0:%hiperget%

targetType      HiPerARC
  ds      =       "portsinuse"
  view    =       "Ports In Use: portsinuse"

html short-desc                 "3Com HiPerARC"

graph   --default--
  precision       =       integer

graph   portsinuse
  color   =   dark-green
  draw-as =   AREA
  y-axis  =   "Ports in use"
  legend  =   "Ports In Use"

Here is a perl script based on a bash script written by Dave C. at PathWay
Computing that will allow you to use cricket to monitor a HiperARC TC at
either the chassis, card, or span level.  There is some cleanup work left
to be done on it, but it is usable as posted.  I'll post updates as they
are appropriate.  If anyone has any comments/etc on this code, please let
me know.
