check_blackberry (updated)

I simply modify the nagios plugin of Philipp Deneu

To push the definition of this check, I update it to add a test for the free licences remaining. Most of system return INTEGER:0 to the OID request 1.3.6.1.4.1.3530.5.20.1.22.1. and 1.3.6.1.4.1.3530.5.20.1.20.1
I just add a total licence variable and the script return the licences remaining.
