The THold plugin is intended to cover this functionality. Does it not meet your requirements?

I'm considering implementing cacti to watch over 50 servers with snmp.
I have looked at the thresholding plugin; and it seems that it fits one of my
requirements to send all kinds of notifications.

But are there perl scripts available for all the services on my list to send snmp data from the client to the server? And are there cacti xml configuration files to handle those snmp traps?

I'm willing to write a few but at least 80% procent must be covered. Can you point me in the right direction for those scripts?

There are lots of scripts and templates in the Scripts and Templates forum. Search this one. For those services which are not yet covered, theses scripts and the online documentation should give you an idea of how to extend cacti's build-in capabilities by writing own scripts. One of the most common methods to make cacti use these remote scripts are
- use NET-SNMP exec/pass features
- use NAGIOS client/server model (find lots of posts on this topic in the forum)
We do use another remote-script-invoking technique: httpd cgi. That is: we implement cgi scripts that gather data and retrieve the readings via wget from the remote server. Others reported doing telnet/ssh scripts...
As to traps: at the moment, cacti does no trap receiving. But it may be possible, that with upcoming plugin architecture a corresponding plugin will be developed...
