Traffic logging on a Content Blade

[erikj]

Hello,

We need to create some statistics on usage of a couple of websites. The tools used to produce this are based on the traffic logs. Whenn we use the server logs we see only 1 client, the Content Switch...

I like to know whether it is possible to get this information from the Content switch. We need to be able to see who is doing what on the webserver.

The setup is a Cat 6513 with a CS blade. Behind this switch is a serverfarm.

you can use the http header insert function to insert the client ip address inside the http header when the CSM forwards clients to servers.

It is then up to you to retrieve this information on the server.

It is not recommended to try to turn on some logging on the CSM to get the list of connections.

You would kill the performance of the CSM.

If you don't want to get the info from the http header, then ask yourself why you only see the CSM address connecting to the servers.

Do you really need client nat ?

You should maybe change the design so client nat is not required and the CSM forwards client traffic unnated so the server can log exactly which client was connected.

Regards,

Gilles.
