vfs.fs.size[e:,pfree] does not return data

[rhanthony]

I have configured a trigger:

{SERVER:vfs.fs.size[e:,pfree].last(0)}<15

But this seems to never return any data to my Zabbix server.

A similar trigger:

{SERVER:vfs.fs.size[e:,free].last(0)}<10000

... returns data just fine. As to all other triggers on this box. For some reason I can't get a pfree based trigger to give me anything back however. Nothing shows up in any logs that I can find as an error.

Found the answer.

The server trigger was expecting Numeric(unsigned).

I corrected it to Numeric(Float), and all works well!

It apparently was returning data, thus no errors in log files, however it was unable to process it correctly so it did not display anything, and the auto graphing pages showed "No Data". As soon as I adjusted the returned format, everything went forward like clock work.
