Please help to config diff trigger

[valen]

Just install Zabix system 2.0 of source codes. Added a linux host. Applied to it a rules from the Linux OS template.
Trigger: Template OS Linux: /etc/passwd has been changed on site.ru {site.ru:vfs.file.cksum[/etc/passwd].diff(0)}>0 ------- doesn't work.
Trigger print an error: Evaluation failed for function: {site.ru:vfs.file.cksum[/etc/passwd].diff(0)}
What is wrong???


P.S. This rule Template OS Linux: Checksum of /etc/passwd is work correct. I can see information from agent.
