device using snmp of angios sampling rate

[michaellin]

I use nagios to monitor the PDU (Power distribution unit) device by snmp,
it can get information of 8 sets of voltage,current,power data from device,
but is that possible using nagios configuration of snmp walk to sampling this device every 30 seconds?
in the nagios the unit is minute! if I input 0.5 in browser to configure this device, is that make nagios check every 30 seconds?
or this is the the limitiation of check?(the minimum time is 1 minute?)

For active checks the interval is whole minutes. So if you enter 0.5 it will round up to 1.
