Nagios check_snmp and 1/0 results

[localzuk]

I have a new environment monitor here, a Room Alert 24e, and it uses a 1 or 0 response for its sensors.

 

1 means 'closed' and 0 means 'open'.

 

Some sensors are normally open and some are normally closed.

 

The issue is how do I set the critical level?

 

If my flood sensor gives a 1, it is fine. If it drops to 0, it is submerged in water.

 

How do I set -c setting? Putting -c 0 alerts on any value basically.

 

How can I do this?

Well, got it working by using the -s option instead.
