CirrusF5 12.0 and AppDynamics
I bought two new F5 appliances and I'm migrating all my configuration from a 11.4.1 appliance to a 12.0.0 HF1 cluster. On my old unit AppDynamics works fine. On my new unit, with the same exact settings as the old one AppDynamics is not working when coming through the F5. When requesting URL /eumcollector/beacons/browser/v1/eum-aab-aum/adrum I don't get a response back. I"m not even sure where to start looking. Any ideas?
I traced it down to a Cipher issue. 12.0 disables any cipher that supports SSLv3 by default. I had to enable the following cipher to get it to work DHE-RSA-DES-CBC3-SHA.

Does that URL require authentication or cookies ? If not, reduce the complexity of the problem by making a request for it from the commandline of the BigIP, and see what that returns. The -v will show you everything the client (curl) sends, as well as everything the server returns.
curl -vk http:///eumcollector/beacons/browser/v1/eum-aab-aum/adrumIf that doesn't work, direct the request directly toward a pool member,
curl -vk http:///eumcollector/beacons/browser/v1/eum-aab-aum/adrumTry the pool member directly from your browser, if you routing allows it, or use a browser running on another another pool member if you have that available to you to use.
Look in the /var/log/ltm log file to see if anything appears there when you're accessing the problematic URL - particularly any iRule errors (which will cause a RST to be sent to your client, and the browser to display a blank page)
