Enabling NCSA loggin

Yazar: enes koc Kategori: Websphere Portal/WCM Server

If you want to view all the Http requests that your application server is handling then you can enable the NCSA log. This might be useful in case of clustered environment to see which server is actually handling particular request or you might be interested in looking at who is accessing the server at what time, load on the server during particular time

You can enable the National Center for Supercomputing Application(NCSA) using WAS Admin Console. Follow these steps
  • Log into the WAs ADMIn console
  • Go to the Servers -> Application Server. Select the server where you want to turn the NCSA log on. On the server details page click on HTTP error and NCSA access logging

  • On the “HTTP error and NCSA access logging” page, check the Enable access logging and Enable Service at startup check boxes. ALso set the Error log level
  • Now go back to the Application server details page, and go to Web Container transportation chain -> WCInboundDefault ->HTTP Inbound channel. Check the Enable access and error logging check box

  • Save your changes and restart the application server.
  • Now when you access the Application server every request would be logged in http_access.log file in the log folder of your application server.

    • This is sample log in my http_access.log file on websphere portal server
