nagios for pool monitors?

Has anyone here tried to use custom HTTP pool monitors with the alias address/port set to pull service status data from the Nagios web interface?     Our thought is that we are using Nagios...

Is nagios possibly looking for an HTTP/1.1 request? You may have to add a few things to your send string, along the lines of the following: 

GET /nagios/cgi-bin/extinfo.cgi?type=2&host=SERVER1&service=CPU HTTP/1.1\r\nHost: \r\nConnection: Close\r\n

You also might try the SuperHTTP monitor script:

It's super flexible and fairly straightforward - the script comments walk though the various options and how to set them.

Ah, also - just remembered. Are you on V10 yet? You might take a look at the inband passive monitor feature that was recently added:
