[Nagiosplug-devel] Suggested alterations to the Performance Protocoll

Hi Yves,

Thanks for the info.

If we use strings, my idea is more advise to the developer of the 
plugin:  Strings are legal.  These will be interpreted as a collection 
of compatible objects, or an enumerated list.  Such as can be displayed 
in a pie chart.

This will therefore allow the use of, say, IP addresses.  But not, say, 
arbitrary lines from a log file.

If the strings cannot be understood in a mathematical or statistical 
context, I think they should be added to the XML data, and not as 
performance data.  This gives the XML a valid use, and the performance 
data a valid use.

By enforcing this rule at this stage, we can give the user data of 
better quality which can be stored and analysed in a more effective way.

We have seen how unfortunately users will happily invent anything they 
can fit into a protocol and hope we can understand it later on.  This 
may just give the users a little help. :)
