F5 LTM Monitor

Taking it ine by line:

port 8447

The port 8447 is only needed as part of the monitor if the pool member is not using port 8447, else you can ignore it.

faildetect 2

Cisco ACE probes uses a failure count but the F5 uses a timeout, so to get the same you need to set a monitor interval of 15 (the Cisco ACE default for http probes) and a timeout of 31 (2 x interval + 1)

ssl version all

Use the default HTTPS monitor cipersuite configuration

request method get url /path/file.html

The request (send) will be a HTTP 1.0 request from the ACE so you can use the following on the F5

GET /path/file.html HTTP/1.0

finally

expect status 200 200

In the receive of the monitor configure you are looking for the status response of 200 OK

200 ok
