check_mrtgtraf returns STATE_UNKNOWN

[Israel Brewster]

I'm pretty sure this is a bug. I ran into the same thing, but was  
able to fix it easily enough in the source code. Looking at the  
original code for this plugin, you can find the section where it sets  
the output state, something like:

if (incoming_rate > incoming_critical_threshold
                         || outgoing_rate >  
outgoing_critical_threshold) {
                 result = STATE_CRITICAL;
         }
         else if (incoming_rate > incoming_warning_threshold
                                          || outgoing_rate >  
outgoing_warning_threshold) {
                 result = STATE_WARNING;
         }

This may not be exact, as I have modified the code somewhat, but I  
think it is pretty close, if not. At any rate, what you'll notice is  
that while the result is set to STATE_CRITICAL or STATE_WARNING,  
depending on the circumstances, it is never set to STATE_OK (as you  
mentioned in your original message), which means that it remains in  
its STATE_UNKNOWN default state if the traffic is OK, to fix it, all  
you need to do is add the two lines:

         else
         result = STATE_OK;

Immediately following the closing bracket on the code block above,  
and recompile. At least, that fixed it for me. I have plugins version  
1.4.3, I don't know if this issue has been fixed in a newer version  
of the plugins or not (current is 1.4.5)
