[baalchina]

Hi, I am trying to draw some graphs in my zabbix 6.0. And in the value, last, min, max are all integer, but the avg value become decimal, like the graph below.
Is there any way to let avg value become integer too?

Thanks a lot.

It is not configured through the system parameters. The processing of obtaining the average value is embedded in the program and can be changed by editing the source codes.
