check_snmp giving warnings below warning threshold

[Jan Scholten]

The -c -w commands are a bit weird.

It's quite easy if you do it that way:
No warning if between 0 and 60:
-w 0:60

No critical if between 0 and 80
-c 0:80

Or other way round:
critical if between XXX and 80
-c XXX:80
warning if between 80 and 60
-w 80:60
