How to log ip addresses?

[Poythress, Lynn]

Hi,

We are running Unicon's uPortal product. It utilizes log4j and we have a log4j.properties file which creates a portal.log file. In that portal.log file it logs users that log on to the portal. We would like it to log the ip address of each user; currently it just shows user name and userid.

Do we modify the log4j.properties file to have it add each user's ip address to the log?

If so, can you point me in the right direction? I read about appenders, but couldn't see any parameters that would specifically capture ip addresses.

Thanks,
Lynn Poythress

Hi Lynn,

I have no idea about uPortal, but for log4j, it has no application
specific configuration, e.g. username, ip address, etc.

The reason you see username, is uPortal application logged it. So if you
want ip address, you need to look into uPortal doc/configuration files,
instead of log4j configuration.

Hi,

I don't know uPortal, but I you can probably do something like this:

* at the start of every request, retrieve the user's IP addess and put it in
the MDC
* in your log4j.properties specify a PatternLayout that outputs the MDC,
something like %X{IP}
* at the end of the request remove the IP from the MDC

see

Maarten,

Thanks for the suggestion. I'll look into PatternLayout.
