Zabbix

Good afternoon! There is a data element, I want to summarize all the values ​​\u200b\u200breceived from it per day. I think that this can be done through a calculated data element and through the sum function. But the syntax is not entirely clear

Answer 1

sum (sec|#number,<time_shift>)
Supported value types: float, int
\\The function starts to evaluate when the first value is received.
In a calculated item, it is written as follows:
sum(" ItemKey ",1d) - sum of values ​​for the last 24 hours
sum(" ItemKey ",1h,1d) - sum of values ​​for the last 1 hour 24 hours earlier
