If you go to the main project website
www.net-snmp.org.uk
there's an "archive search" field immediately below the navigation

The simplest approach would probably be to use the "logmatch" directive
to check for such failures in the appropriate system log file.
I'd also suggest looking at the 'denyhosts' mechanism, which does a
fairly good job of blocking probe attempts.
