error_logs per domain

maqsium
Hi, I have dedicated server and have 13 busy sites running on it. I would like to know how can I see error_logs specific to domain? At the moment, I see all errors in /usr/local/apache/logs/error_logs But it is very difficult to identify which application/user is throwing these errors.

    Hi, Typically the errors provide enough information to determine the account/domain, but there are a few that do not. You can also configure a local error log using the 'error_log' directive. How you implement this will be dependent on your PHP handler. If using suPHP, you may add the directive to your local 'php.ini' file. If you do not have one, you may create one. If using DSO you'll need to implement this through a '.htaccess' file with the the PHP directives prepended by 'php_val' or 'php_flag'. You can determine your PHP handler at WHM > Service Configuration > Configure PHP and suEXEC or with the command below from the root user:
    /usr/local/cpanel/bin/rebuild_phpconf --current
    Thanks,

    Hi, If php-SUEXEC enabled then just use "tail -f /usr/local/apache/logs/error_logs | grep username" username=replace with actual username. Thanks, Ravijas

    Hi, I'm using mod_fcgid with apache and suEXEC on Apache. My apache does not generate any domain/user specific application, it always gives PID and IP in each error, thats all. Nothing more than that, IP is simply my server's IP. I have 13 websites running on it and can't figure out which website is giving error.

    Hi, Try temporarily switching to suPHP and then monitor logs. Thanks,

    Its live server with huge traffic, it is not possible to move from mod_fcgid. Any other alternates?

    I think that may be your best option. You can go back to the idea of a custom local PHP error log. You could also try a while loop that parses the Apache error log for these errors against lsof/netstat. You could also try manually running each page from the command line. fcgi by default just does not provide very verbose logging.

    Hello, The username of the account is typically present in the global /usr/local/apache/logs/error_log file. Could you provide an example of an entry that you can not determine the cause of? Thank you.

    Micheal, I think you referring to the problem given in the log, rather, I would like to see which website/user is having those error. My objective is to show the website/username in the error log.

    You could add an "ErrorLog" entry to the VirtualHost of each account as documented here: However, note that some errors are global and for the Apache service itself. Thank you.
