NagTrap

The sourceforge page and the nagios.org address seem both no longer to be maintained now. NagTrap was a great tool for pushing traps in to a MySQL database for viewing, but for larger installations, the method for querying each host from Nagios for traps in the database was hugely inefficient. I'm still using NagTrap to store traps for a short while in the database so I can view and search them easily, but I use an exec from the snmptt config to submit trap events to Nagios via the command pipeline passively as it's more efficient than querying the NagTrap database using an active service check (and will work even if something goes wrong with the database).
