Bowen looks at error log files, which can provide valuable information when your Apache Web server misbehaves. As you'll see in coming weeks, these two logs are generated by different processes. And you'll see in this article that the format of the entries in the error log are rather different from the entries in the access log that we saw last week. But the two http 404 apache logs are similar, in that they both provide a lot of useful information which you can use in analyzing how your server is being used, and what is going wrong. Where's the File? Your error log file should be in the same location as your access log file. It will be called error_log, or, on Windows machines, error.log. The location of your error log can be configured with the ErrorLog directive: ErrorLog logs/error.log The location, unless it has a leading slash, is assumed to be relative to the ServerRoot location. In a default Apache installation, the log file is located in /usr/local/apache/logs As before, if you installed with one of the various package managers out there, you may find it just about anywhere. What's in It? The error log, as the name suggests, contains a record of everything that went wrong while your server was running. It also contains general diagnostic messages, such as a notification of when your server was restarted, or shut down. You can set your log level higher or lower to control the amount, and type, of messages that appear in your log file. This is configured

Now our log file (apache) that writes this errors is in "access.log" file. We want to have 404 not found errors for example in notfound.log I did a test writting in apache2.conf: LogFormat "%{X-Forwarded-For}i %l %u http://stackoverflow.com/questions/21314788/apache-404-error-log-to-a-different-log-file %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" notfound and in VirtualHost of apache sites-available: CustomLog ${APACHE_LOG_DIR}/not-found.log notfound expr=.*404.* But I got "error in condition clause" I tried to set a env variable in VirtualHost too: SetEnvIf expr .*404.* httpcode And call it in CustomLog expr but didn't work.

This should allow you to set an environment variable using the ResponseSetEnvIfPlus directive and then use that envirionment variable to force a custom log file. share|improve this answer answered Jan 29 '14 at 0:21 rmeakins 899611 show an example? –ivo Welch Mar 9 at 5:50 add a comment| up vote -1 down vote You can refer to Apache CustomLog Manual.

Just add these lines to .htaccess: # Don't log missing files RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(content\asdf)$ - [R=404,L] It uses mod_rewrite. RewriteCond is there to make sure that file indeed doesn't exist. Files that do exist will be served as usual. R=404 says to send 404 Not Found status code when client accesses any files that contain "asdf". You need to modify the expression in parenthesis, on the last line, to suit your needs. This answer is also found here. share|improve this answer answered Jun 4 '14 at 16:31 Gaia 68911536 add
