The implementation of file monitoring commons-io is located in the .monitor package. Note that different versions require different JDK support, 2.7 requires Java 8 and above. ![]() Introduce the corresponding dependencies: commons-io commons-io 2.7 Here we need to use an open source framework to achieve this, which is the commons-io class library that almost every project will introduce. If you encounter similar problems, you can search and solve them yourself. I have not verified other operating systems. The API has also been raised on Stack Overflow about Java 7 having a delay under Mac OS, and even Windows and Linux systems. Only files and directories in the current directory can be monitored, and subdirectories cannot be monitored.Īnd we also see that monitoring can only be regarded as quasi-real-time, and the monitoring time can only take the three values provided by the API by default. In the previous article Digging Through a Bug in the JDK Monitoring File, a specific example has been written, and its shortcomings have also been proposed.Ĭompared with Scheme 1, it is simple to implement and has high efficiency. If there is a change, it means the file has been modified and needs to be reloaded or processed with corresponding business logic. Through timed tasks, the last modification time of the query file is polled and compared with the last time. This solution is the simplest and most straightforward solution that comes to mind. Today I will share three solutions: Scheme 1: Scheduled task + File lastModified Of course, in other business scenarios, such as dynamic loading of configuration files, monitoring of log files, and monitoring of FTP file changes, similar scenarios will be encountered. If you have enabled logging of slow pages, ColdFusion will track those here.When studying the rule engine, if the rules are stored in the form of files, it is necessary to monitor the specified directory or file to sense whether the rules have changed, and then load them. Server.log: When your server starts up, it will log details of that process here. To enable it, head over to the Mail Logging Settings. If enabled, this log will capture TO, FROM, and SUBJECT from all mail sent. Mailsent.log: Its possible to keep a log of all mail sent by ColdFusion. You can adjust what is captured in the Mail Logging Settings. This your go-to log for any issues with sending mail from ColdFusion. Mail.log: Issues with the mail server can be tricky to debug, since it is sent (and can fail) in a background process. Note that Event Gateways are an Enterprise feature.Įxception.log: This is a more detailed version of the application.log, and includes stack trace information to help identify issues. Inspect this file periodically to ensure your application is not breaking in a way you were unaware of.Įventgateway.log: This log contains any errors or exceptions thrown by the Event Gateway. Note that you can specify log setting per application which is very helpful because you can have an application log for each application.Īpplication.log: A summary of most errors thrown by ColdFusion are captured here. Log files are one of the most powerful tools for debugging applications and are very useful for performance tuning. Trying to manipulate very large log files in the browser can be unwieldy. While it is convenient, we have found it much more productive to investigate these files in a dedicated log viewer or text editor. ![]() log files within your log directory (as specified in the Logging Settings). ![]() Here ColdFusion provides an interface to view and manage all. ![]() Optimizing, Tuning, & Scaling ColdFusion – Threading.
