in dealing with raw logs. Error Log Related Directives ErrorLog LogLevel The server error log, whose name and location is set by the ErrorLog directive, is the most important log file. This is the place where Apache httpd will send diagnostic information and record any errors that it encounters in processing requests. It is the first place to look when a problem occurs with starting the server or with the operation of the server, since it will often contain details of what went wrong and how to fix it. The error log is usually written to a file (typically error_log on unix systems and error.log on Windows and OS/2). On unix systems it is also possible to have the server send errors to syslog or pipe them to a program. The format of the error log is relatively free-form and descriptive. But there is certain information that is contained in most error log entries. For example, here is a typical message. [Wed Oct 11 14:32:52 2000] [error] [client 127.0.0.1] client denied by server configuration: /export/home/live/ap/htdocs/test The first item in the log entry is t

I want to define a file name and so that all errors and warnings get logged into it. php error-handling share|improve this question asked Aug 20 '10 at 14:15 Gorep 589253 add a comment| 5 Answers 5 active oldest votes up vote 199 down vote Use the following code: ini_set("log_errors", 1); ini_set("error_log", "/tmp/php-error.log"); error_log( "Hello, errors!" ); Then watch the file: tail -f /tmp/php-error.log error log file Or update php.ini as described in this blog entry from 2008. share|improve this answer edited Apr 7 '13 at 5:35 Dave Jarvis 16.4k24106204 answered Aug 20 '10 at 14:32 Aman 2,4131815 30 ini_set does only work if that code is executed. Not useful for code that has parse errors because the error will be before the code is executed. Instead write those changes into the php.ini. –hakre Apr 16 '13 at 23:31 7 If you can't edit php.ini, you should be able to add this in the .htaccess : php_flag log_errors on php_value error_log /home/path/public_html/domain/PHP_errors.log. See perishablepress.com/… –Matthieu Jan 8 '14 at 8:47 I have a question, how to get the error.log file to get created in my htdocs folder instead? –Tommy Mar 5 '14 at 21:51 I guess you just change the folder from tmp/php-error.log to which ever location you desire? –Luke Apr 16 '14 at 12:37 This crashes my PHP in 5.4.0 –Supuhstar May 10 '14 at 3:05 | show 1 more comment Did you find this question interesting?

logs to troubleshoot problems About log files Intro Message Tools Error log PHP errors Access Watchdog Acquia provides access to a number of log files that can help you troubleshoot various problems. For a full list of log files, locations, and descriptions, see About Acquia Cloud logging. Acquia Cloud customers can live stream their log files from Acquia Insight. Read Streaming log entries in real time for details. If you are having issues on a non-Acquia site, you can spot many errors by using the tail and grep commands on one of the log files. For example, tail -f lets you see errors in real time as they're logged: You can directly access the log files for each of your web servers using SSH. If you are hosted on Acquia Cloud, you cannot access the aggregated access and error logs on the load balancers. Here's a short list of examples of how to find problems using these tools. Using the tail command You can use the UNIX tail command in a shell to view the last ten lines or so of the log. The command has a number of options, including the very helpful -f, which streams the log file as it is updated. The action looks like this: tail -f access.log [perform an action in your web browser to make the error happen] ctrl-c tail -f error.log [perform an action in your web browser to make the error happen] ctrl-c If you do not use the -f option, opting for tail error.log, your results will look something like this: [Fri May 31 17:48:29 2013] [warn] [client 10.126.254.118] mod_fcgid: can't apply process slot for /var/www/html/test/docroot/index.php [Fri May 31 17:48:29 2013] [warn] [client 10.126.254.118] mod_fcgid: can't apply process slot for /var/www/html/test/docroot/index.php [Fri May 31 17:48:29 2013] [warn] [client 10.126.254.118] mod_fcgid: can't apply process slot for /var/www/html/test/docroot/index.php Using the grep command The grep command provides powerful pattern matching tools for searching for strings in one or more files at a time. It has options that enable the automatic count of pattern matches. To count the number of these errors in the most recent log, run the grep command to count the matching errors: grep -c slot error.log This should return a number, like this: 91 If you want to count the errors across all the logs, you can do that with zgrep, and now you can see the trend over time: zgrep -c slot error.log* This returns a list of logs, and the number of times that string appeared in each: error.log:91 error.log-20130301.gz:587 error.log-2013030
