Save all the settings and you have a new alert system set up now. That will create the proper scope for your file watcher. The cause seems to be related to how Sitecore handles the deployment and modification of large numbers of configuration files. link and create a new scope named error.log - you can see the settings in the screenshot below:īasically, what you do is to choose your error file and and include it. In order to make the scope, you’ll have to click the. In the new watcher, choose the following options as per the screenshot: Toward the bottom left hand of the main window dialog, click the + to create a new file watcher. In the search box, type watcher which will bring up the Tools > File Watchers dialog. FILEWATCHER ERROR WINDOWSmenu item - this might be under the File menu on Windows - or under the PHPStorm menu on Mac. For Ubuntu/linux, you might use the notify-send program. For MacOS, I’d suggest terminal notifier (this is what I’m going to use for the demonstration). FILEWATCHER ERROR INSTALLThe Howįirst, you’ll need to install a terminal notifier application. Txt file into the watched folder and the FileWatcher didn't notice it so the. Then the file that was processed is deleted after processing it. The action it will display is to create a dialog or popup that let’s us know that there is a change to this file. The watched folder and the folder the FileWatcher copies a file to be processed to before the file is processed. However, this watcher will provide a fallback for when we might not notice. We might also notice the error on the screen or in our test. If there are any changes, that means that an error happened. The Whatįor our PHPStorm File Watcher, we want to watch our logs/error.log file for any changes. However, any action can technically happen if there is an error. PHPStorm file watchers typically are used to do things like compile javascript or SASS files automatically. For this reason, I’ve started using file watchers in PHPStorm to alert me of errors in my application log files. You might not even notice that something went wrong - if you’re not paying attention. I'm not sure if this is an underlying fsevents issue/bug or what, but if using recursive paths, when a file is removed an event is triggered, when using a specific path to monitor, if the file. One of the things that can happen with PHP is that a certain level of error can happen (say a Warning type) but the script can continue. FILEWATCHER ERROR CODEThis helps troubleshoot code issues that I might miss otherwise. In my applications, I have the same level of logging locally as I have in production. However, if you’re logging errors locally, you might forget to look at them. However, when they happen during local development, we usually rely on seeing a unit test fail or a display that doesn’t match up. When errors happen remotely, most programmers will check the log file. For example, in one of my Laravel projects, I have two log files, one for errors and one for info or debug level information. This might be in the PHP error log itself or in a log file. When PHP errors happen, often times there is an error log.
