check randomality in zabbix

[ShivaS]

Hi, I have some script which runs and checks date of the file.
Date i can redirect to some file to perform checks.
What i need is to see that the results i get are frequently change (meaning that some process is running well and not stucked)
how may i check in zabbix that results are not equal and always changing?
does someone have any idea?

thanks

{host:item1.max(300)}#{host:item1.min(300)} ?

Thanks for the reply, seems to be simple, didn't think about it at all.
Now activating and checking.
But I'd use = as delimeter between 2 data-fields.
Since i need come to situation when trigger activated upon no-data change

thanks once again, Alexei!
