I was trying to find more information about auditspd and
What it is and what it is used for.
I am trying to evaluate the impact of this as a dispatcher when using
other
3rd part HIDS tools.

Thanks

It is a new event multiplexor. This will allow the development of plugins that 
can anylize the audit data in realtime for certain things or the development 
of plugins that either transform the data into another format and/or move the 
data to another machine.

I know of no plugins except the one that IBM submitted. I am developing some 
but they are not released. So, today I'd say there is no interference. Down 
the road there could be if you configure it that way. No plugins will be on 
by default with the possible excpet of af_unix which is needed by 
setroubleshooter.

I think you mean audispd. Steve Grubb can probably give you more 
complete information as this is an area that has been under active 
development and the facilities available depend on the version.

In the current state one connects to a UNIX domain socket 
(/var/run/audispd_events) and you read audit records one per line. The 
audit records need to be assembled into audit events. The auparse 
library is a good tool for this purpose and has a 'feed' interface where 
  one can read N bytes off the socket and be called back when a complete 
event is seen. There is also a python module supporting this interface.

Steve has also added support for 'plugins', a module which rather than 
reading off the audispd socket will be fed the same data via stdin.

I took a look at the audit website http://people.redhat.com/sgrubb/audit 
but it looks like some of the info is out of date, especially the real 
time link.

What one does with the audit events after you've read them is up to you.
