Hi, http://httpd.apache.org/docs/2.2/en/mod/mod_log_config.html#formats I'm using %D to log the time taken to serve requests. I found the time might be 0 in nonspecific requests. The rate of 0 serving time goes the same trend with server load. Does it mean some kind of timeout? Thanks. -- islue --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
