max & etc function.

[sauron]

First i'm add new item icmpping type is Numeric (Integer 64) and add trigger:

({Host.collector:icmpping.max(#10)}=0)

But status trigger set to UNKNOWN and in log i'm got:

030122:20060227:115608 Evaluation of expression [({11217}=0)] failed [Unable to get value for functionid [11217]]
030122:20060227:115608 Expression [({11217}=0)] cannot be evaluated [Unable to get value for functionid [11217]]

I'm change trigger expression:

({Host.collector:icmpping.max(300)}=0)

But status trigger not changed and in log:

030122:20060227:115838 Evaluation of expression [({11219}=0)] failed [Unable to get value for functionid [11219]]
030122:20060227:115838 Expression [({11219}=0)] cannot be evaluated [Unable to get value for functionid [11219]]

When i'm change trigger expression to:

({Host.collector:icmpping.last(0)}=0)

Trigger status going FALSE. Why max function not work

Huh found. agregate function work only float data type.

Fixed by patch.
