What is the difference between

asynchronous engine

nmap engine

classic engine

in settings/general/check the online status page?

 

Also, I noticed that to get the username logged in to the computer, I have to do a full scan. Do I have a setting wrong?

Thanks!

Asynchronous engine uses an external tool that pings IP addresses in batches of 300 using the asynchronous ICMP requests, as its name states. The result is rather fast, but not always 100% reliable.

Nmap engine uses external nmap.exe tool that pings IP addresses by its own logic. Pretty fast as well.

Classic engine uses internal technique with creating 20 threads (by default) where each thread pings one asset at a time. It's rather slow, but more reliable, as we've found out. It's selected by default.

Actually you can try them all and see which one suits you best.

 

Please explain your second question, as I'm not sure what do you mean by full scan, and when do you get no username.

The normal timed ping doesn't get the user name logged in. I have to do a RESCAN to get the user name logged in.

That's completely obvious, how would you get a name of a logged in user by simple ping? Of course you need to scan a computer :)
