the Nagios parser definitly seems broken, I was tying to fix it but its just easier to use the Cacti format

item:value item2:value2 etc

this is 3.2.1.  I did not originally notice the option to select the parser and it was on Auto, so maybe just the Auto parser is broken but we'd already changed the script to Cacti, which works with Auto and  Cacti.  The end result is the same, I just thuink the documentation needs to be better. Linking to the Nagios website is really not the best way to document this. Just put in an example of what the Nagio parser is expecting, including multi-value responses.

Sure does and I tried that format. If it is THE correct format maybe the Admin Guide (docs/DOC-9451) should be updated too because that page links to the Nagios website that shows one result per line.  The Nagios parser is even doing a string split on \n when it checks for multiple values.

the Nagios parser does work, just not for multiple values.
