3. What Should You Do Upgrade Successfully
3.6.2 Monitor Your Logs to Check If Your Application is Working
You need to monitor your logs to check if your application
is working. So your application also needs to generate log files that you can take a look and confirm that everything is working correctly. If something is wrong you'll also need to have error logs.
The next recommendation is to monitor your logs to check if your application is working.
So your application also needs to generate log files that you can take a look and confirm that everything is working correctly. If something is wrong you will also need to have error logs.
Activity logs are something. Error logs are something else. PHP has its own error log.
I suggest that you have the PHP error log enabled, so you can check if there are issues in PHP that are affecting your application. And you also need to monitor those logs.
The activity logs and the error logs. The error logs are more important because they reflect things that are not working correctly and you need to fix those first. Okay?
So what I suggest to monitor your logs could be any tool but I have my own class that I use. I use a class that monitors log files. You give the path of the log file. It could be the PHP error log file.
You also need to be able to enable the PHP error log file in the PHP configuration because it is not enabled by default.
So once you change that configuration, restart Web server to make sure that PHP configuration is reloaded, you will be able to track any errors that happen in PHP.
That is really, really important because many issues that you have in your application lead to errors in PHP code and you can monitor the PHP error log the to make sure there are anything there that you need to fix.
Okay? I'm going to provide the link to the package that you can download or install using Composer, or whatever means you want. I use this as a separate script with a class. I have a script that calls a class that does that.
And you can also check a tutorial article that tells about how to detect bugs in your environment as soon as possible using this log watcher class. Okay?
