RedHat 6.x Zabbix 3.0


 Description   

We notice a small problem on the Calculated Item documentation of Zabbix 3.0, in every example of "last" function the parameter1 is not reported.
As i remember before zabbix 2.2 release this parameter was an option but since 2.2 is a requirement (I have tested on Zabbix 3.0).
Could you update the documentation to reflect this requirement?

Ref.https://www.zabbix.com/documentation/3.2/manual/config/items/itemtypes/calculated
Example:

Use of function last:
100*last("vfs.fs.size[/,free]")/last("vfs.fs.size[/,total]")

The other way round, I guess.

Aren't examples working?

Comment by Dimitri Bellini [ 2017 Mar 21 ]

I'm very sorry... I have now retested everything and the example is working ok.
My problems with calculated items probably was coming from "Configuration Cache" reload time and fast item modifications... The same old problems
Please close the ticket.
Thanks very much
