I like ManageEngine Netflow Analyzer to monitor network traffic on our ASA’s. There are a few settings that are specific to the tool to get it working. I found this blog post which is a perfect how-to for you to get your ASA going with Netflow.
Instead of always having to write an HTTPS redirect on your webservers, you can have the ACE handle this work for you.
The first step is to create your redirection “rservers”. In my example it matches everything. If you want to only redirect a specific URL, then change the content after “https” to match what you want.
rserver redirect HTTPS-REDIRECT webhost-redirection https://%h%p 302 inservice
Add to a redirect serverfarm:
serverfarm redirect FARM-HTTPS-REDIRECT rserver HTTPS-REDIRECT inservice
Once you have the serverfarm configured, apply to the respective policy-map. To match everything apply it to a class-default, if you want to redirect a specific URL assign it against a policy-map with multiple class definitions.
policy-map type loadbalance first-match POLICY-HTTPSREDIR class class-default serverfarm FARM-HTTPS-REDIRECT
Apply the policy map to your multi-match policy.
policy-map multi-match POLICY-STG1 class CLASS-MYIP loadbalance vip inservice loadbalance policy POLICY-HTTPSREDIR loadbalance vip icmp-reply class SNAT nat dynamic 1 vlan 100
Add that to your interface and you’ll be good to go.
