belongs. Can be any string, but the general practice is to use the name of the 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 drupal 7 error log 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. WATCHDOG_DEBUG: Debug-level messages. $link: A link to associate with the message.

Some errors are only reported when all PHP error reporting is switched on. Without the error reporting on, you get the dreaded White Screen of Death. Check for errors behind the scenes As an alternative between showing no errors and showing all errors, you may wish to monitor the errors being generated by your site by running tail -f /var/log/apache2/error.log on your server.

2015 by William Hetherington Tail is command for Unix and Unix-like systems (like OS X) that allows you to take a peek at the contents https://drupalize.me/blog/201506/using-tail-debug-drupal-sites of the end of a file. From the manual page: "tail - output the last part of files." Tail can be really useful for debugging purposes, or for taking a look at https://www.loggly.com/blog/logs-for-drupal-why-you-need-them-and-how-to-do-it/ the recent access logs from your Drupal setup. Tail can be particularly useful in a production environment when you may not have PHP error reporting enabled, and need to find the cause of error log serious errors with your Drupal site. But this isn't just for Drupal sites. You can use Tail on any text file on your system. This tutorial is based on the free Tail - Command Line Debug video from our Command Line Basics series. Prerequisites You know how to access a Drupal site via the command line (using Terminal or similar program). It can be installed either drupal error log on a local site or a remote server that you know how to access via ssh. You know which web server you're running Drupal on. Assumptions If you are running Apache as a web server on Debian or Ubuntu, or OS X, your log files will likely be located in the /var/log/apache2/ directory, and their names will likely be: access.log and error.log, although depending on your system configuration, this may be different. For example, if you are running MAMP, your log files will be located in /Applications/MAMP/logs. If you're not running one of the operating systems I just mentioned, or Apache, check your web server's documentation for your OS to determine your default log location. For the purpose of this tutorial, we will be assuming that the access.log and error.log are located in /var/log/apache2. As mentioned above, this may be different on your system. Running the Tail Command Here's an example of how to use the tail command to view the last bit of Apache's access log: tail /var/log/apache2/access.log Running this command will print the last 10 lines from your access log. This can be useful if you want to see the most recent reques
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
