what is this Expression mean

[islam]

hello,
I have an item that calc bps and I want to sum it for a week and day and hour I came up with this Expression but I am not sure the output what is it

sum(/ryvps02/net.if.out[eth0],1d)>100G

can you tell me the output of this Expression

[islam]

just expiration meaning I need to be confirmed about the results

sum of values (looks like outbound bytes for eth0 interface) for 1d is more than 100G... 1d here is not 00:00-24:00, but it is a sliding 24h window... from "now" 1d back.
If you want to calculate 00-24... you need to use time shift.. https://www.zabbix.com/documentation...ion#time-shift

Obvious....
From here : https://www.zabbix.com/documentation...ions/aggregate

sum (/host/key,(sec|#num)<:time shift>)

Sum of collected values within the defined evaluation period.

and from here : https://www.zabbix.com/documentation...ion#time-shift

1d:now/d+1d	Today

Your expression is "sum of values for today (starting from midnight) is more than 100G"...
