module calling watchdog(). $message: The message to store in the log. Keep $message translatable by not concatenating dynamic values into it! Variables in the message should be added by using placeholder strings alongside the variables argument to declare the value of the placeholders. See t() for documentation on how $message and $variables interact. $variables: Array of variables to replace in the message on display or NULL if message is already translated or not possible to translate. $severity: The severity of the message; one of the following values as defined in RFC 3164: WATCHDOG_EMERGENCY: Emergency, system is unusable. WATCHDOG_ALERT: Alert, action must be taken immediately. WATCHDOG_CRITICAL: Critical conditions. WATCHDOG_ERROR: Error conditions. WATCHDOG_WARNING: Warning conditions. WATCHDOG_NOTICE: (default) Normal but significant conditions. WATCHDOG_INFO: Informational messages. WATCHDO

Use the watchdog() function to add an entry to this log from your own custom module. When Drupal bootstraps it uses the PHP function set_error_handler() to set its own error handler for PHP errors. Therefore, whenever a PHP error occurs within Drupal it will be logged through the watchdog() call at admin/reports/dblog. If you look for PHP fatal errors, for example, in /var/log/apache/error.log and don't see them, this is why. Other errors, e.g. Apache errors, should still be logged in /var/log, or wherever you have it configured to log to. share|improve this answer edited May 2 '14 at 15:44 answered Jun 23 '11 at 2:10 Charlie S 2,90912451 Why not just use error_log( $message + $vars + $etc )? –AlxVallejo Oct 28 '13 at 17:03 You could do that. The watchdog table has more than just the message, such as the module or library or whatever that threw it, a serialized array of data that you might want to store (information related to the error, outside of a message string), the location, the referrer, the currently logged in user, etc. So throwing
June 28, 2013 | Drupal Twitter Have you ever seen an error on your Drupal site that says:"The website encountered an unexpected error. Please try again later."There are over 700 people who have reported the same problem on the Drupal.org forums.If you have this https://www.ostraining.com/blog/drupal/error-logs/ error or similar errors and are thinking, "OMG! Now what?", then hang tight.We're here to help with https://www.loggly.com/blog/logs-for-drupal-why-you-need-them-and-how-to-do-it/ this tutorial. We'll show you how to diagnose and solve errors that appear on your Drupal site.Print Errors to the ScreenIf you see an error with no information or you see the White Screen of Death (WSOD), one of things you should do is start looking for errors.To make errors visible on your Drupal website, find the index.php file in the main directory of your error log site. Open index.php and add this code directly before the very first line of the file: error_reporting(E_ALL); ini_set('display_errors', TRUE); ini_set('display_startup_errors', TRUE); In the example below, I have an error with the Weather module. I have deliberately loaded the Weather module to one of my test sites in an unconventional way and broken the code in an effort to trigger an error:This error tells me that something is wrong on line 629 of weather.module. Of course, if this was a production site drupal error log and errors were not enabled to print to screen, a WSOD would send me running to my error logs to see the same message.(As a side note, it is not common practice to upload the weather-7.x-1.5 directory and it had nothing to do with triggering an issue.)Find Your Error LogsLet's assume you got a WSOD and need to look at your error logs. I am not a server expert but I can tell you where my error logs are located. As you can see from the screenshot above, my error logs are at the same level as my html directory. The html directory is where your Drupal files and directories are stored.View the ErrorsThe control panel I have on my server allows me to check a box and click edit, as shown in the screenshot above. If your server doesn't have this feature, download the error log file and view it locally.As you can see, it's telling me the line 629 in weather.module has an issue. It also says it can't find a favicon.ico file. Hmmm. I'll have to fix that. Anyway, now that I know where to look for the problem, I can open weather.module and see what might be wrong.Restoring Your SiteSome issues are triggered when a user lands on a specific page while others seem to affect all your pages. If for some reason, you can't reach /#overlay=admin/modules or /admin/modules and disable the problem module, try the following. Launch PHP
development. Your QA people can barely keep their eyes open because they have worked so hard. Your lead developer who's responsible for the deployment is almost dehydrated from so much pressure and sweat. But it's all worth it. Your app is live. Now everybody goes to sleep, and your pampered app is all alone, serving your data to the entire world. You forgot one thing: to give it a phone to call home and tell you something went wrong. You should have logs Debugging is like being the detective in a crime movie where you are also the murderer. — Filipe Fortes (@fortes) November 10, 2013 Arguing that logs are important is like arguing that automatic tests are important. Everybody knows that. It’s just that very few actually do it. The biggest barrier is that it's hard to take the first step. In Drupal, for example, there's a watchdog that can send your errors to the DB, but it's unrealistic to expect anyone to dig up an error in real time on multiple live apps. Drupal also provides a Syslog module that can later be used to forward the logs. However, since many sites are hosted on platform solutions such as Pantheon, Syslog isn't always available. In order to lower the barrier, Gizra has developed as part of its "The Gizra Way" a general logging module that can send your watchdog data via HTTP called Logs HTTP. You just need to set the URL and the severity level you would like to capture, and you're done. This module can work with a variety of log management solutions, including the open-source Logstash or the cloud-based Loggly. Here is what the configuration for Logstash looks like: Figure 1: Configuration page. Just add the HTTP endpoint. Figure 2: Logstash with a JSON coded message, capturing an exception Since we want to concentrate our efforts on the actual development of the app (the same reason that led us to use services like Pantheon in the first place), we've decided to go with Loggly. The price is reasonable, and it provides many of the features we want, in particular the ability to send real-time email alerts. Logs HTTP module The Logs HTTP module takes over your exception handler, so whenever an exception is thrown, the backtrace debug_backtrace() of the requ
