good plugin

hi, this is a great little plugin for checking the FT state of a single context.

Would it be possible to query further up the oid tree to check for multiple FT groups?

something like [nagios@nagio01 libexec]$ snmpwalk -v 2c -c public 192.168.1.1 1.3.6.1.4.1.9.9.650.1.1.4.1.2
SNMPv2-SMI::enterprises.9.9.650.1.1.4.1.2.1.1 = INTEGER: 3
SNMPv2-SMI::enterprises.9.9.650.1.1.4.1.2.1.2 = INTEGER: 5
SNMPv2-SMI::enterprises.9.9.650.1.1.4.1.2.1.3 = INTEGER: 9
SNMPv2-SMI::enterprises.9.9.650.1.1.4.1.2.1.4 = INTEGER: 9
SNMPv2-SMI::enterprises.9.9.650.1.1.4.1.2.1.5 = INTEGER: 5
SNMPv2-SMI::enterprises.9.9.650.1.1.4.1.2.1.6 = INTEGER: 9

if it could be happy with either active/standbyhot or standbyhot/active that would be a benefit as we split the load between prod and test. It would be good if it simply alerted on state change.

thanks
