Good day.

Can zabbix check some snmp values at one?
I need this for check cpuload over snmp (I don't want to use zabbix_agent)

Thank you, but cpu usage percent calculated by this algorithm: 1- (delta ssCpuRawIdle)/(delta sum( ssCpuRaw*))
So, i must get all ssCpuRaw* snmp values at one.
Is it possible?

There are a second problem. I have MemTotal and MemAvail values. How can i calculate a memory usage in percents?
There are a very flexible expressions for calculating triggers values and no expressions for calculating items values...
