Hey Guys,
Whats the best way to tail a log, look for something specific all the time and send it to SNMP OR have it as an alert?

Start with the nagios exchange. There are a number of log related plugins for string checking, regex matching etc:

Reporting through snmp might require a custom solution.

Well the thing is the logs are on a remote server, and i want to tail it real time. i would need to have this custom tail log program / snmp run on that server and display via snmp

If you can, nsca would likely be a good option for this. Otherwise I think this is a bit out of scope for what we would handle as you'd likely be looking at a very specific snmp server.

well the reason i ask is b/c of for example the check_yum right? It checks the yum updates and checks for security updates and warns via snmp to a service created in nagios.
so how could i do the same for something i want to tail in a log? no?

We had a speaker, Robert Bolton, at last years conference go over this very topic, you can see his presentation slides and additional files here

Look for
"Custom SNMP OID Creation for System Monitoring"
Also the first 10 minutes are on youtube
