Web Server Access logs

Search Tips   |   Advanced Search

All incoming HTTP requests are logged here. Logging degrades performance because of the (possibly significant) I/O overhead.

To turn logging on or off...

1. Edit httpd.conf.
2. Search for a line with the text CustomLog
3. Comment out this line
4. Save and close httpd.conf file
5. Restart IBM HTTP Server.

By default, logging is enabled, but for better performance IBM recommends that you disable the access logs, or at least keep the log format not too verbose, in order to avoid to much hard disk I/O.

If you decide to do access logging, make sure to turn reverse host name lookup off using the HostnameLookups Off directive, or else each client request results in at least one lookup request to DNS.
