[munin-users] Problem with warning and critical properties

Hi. So far, I have been able to manage my Munin installation by 
myself. At this point, though, I am encountering what appears to be a 
bug and I need help.

I wrote a plug-in that reports, among other things, the number of 
processes of a certain program that are currently running. I want to 
trigger an alert if no such processes are found. All is well and my 
plug-in contains the following instruction:

processes.critical :1

which, according to 
<http://munin.projects.linpro.no/wiki/fieldname.warning> indicates 
that a critical flag should be raised if the value ventures below 1. 
Since this counts processes, the only other possible value is zero.

The problem is that I get error messages as soon as the value is NOT 
1, not as soon as it is LESS than 1, such as the following:

CRITICALs: Processes is 1.99 (outside range [:1]).

Note that I am not sure why Munin would report 1.99 processes as this 
should be an integer value. This value is seen as a "gauge" value by 
Munin.

I run Munin version 1.2.4.

Your help is appreciated.
