Hi there, i can't figure it out how to make work this function. I have one item that get values by snmp from printer. I created another item as "calculated" and i want to calculate difference between last value and value that was for example 1d before. I read zabbix manuals for functions but with no luck, function doesnt work. So what i tried:
Result always - 0
I will be grateful for any help, thank you.
Code:
last(/Minolta1/pages_count) - last(/Minolta1/pages_count,30m)
I will be grateful for any help, thank you.
