check_sfp_juniper

The plugin receives the warning and critical power limits (from the SFP firmware) and compares the current readings with these and will then either issue a WARNING or CRITICAL if limits are exceeded.
Interfaces that are admin-down are ignored (laser turned off). Regular interfaces that are down are monitored and will cause a CRITICAL state, so please disable these if they are not used (also saves the transceivers life due to the laser beeing shutdown).
Only ge- and xe- interfaces are monitored, however this can be changed
by modifing the xe-|ge- filter in the script.

This plugin is based on check_cisco_sfp.
Currently does not support the temp/supply/bias options, only power is working.

Usage:

./check_sfp_juniper.pl --hostname your_router_ip --community SECRETCOMM --type power
