Hello! The Yii-Debugger is very nice to analyse the page. But it tracks everything. Independent from beeing a normal request or an error. This is good for testing, but I want to analyse my live page as well, but only the errors. I can look into the /runtime/logs/app.log file, but this is not very comfortable. Is there a way to display the content of the app.log file in the Yii-Debugger?
In debug there are filters that you can use to get errors only.
Hello samdark! Nice to get a reply from one of the main developer!!
Yes, but in Production mode I have thousands of requests. But I only want to log the errors. I don’t know where to set this option. In /frontend/config/main.php I already specified [components][log][targets][levels] => [error]. But this only affects the /runtime/logs/app.log file.
'log' => [
'traceLevel' => YII_DEBUG ? 3 : 0,
'targets' => [
[
'class' => 'yii\log\FileTarget',
'levels' => ['error', 'warning'],
],
[
'class' => 'yii\log\FileTarget',
'levels' => ['error'],
'logFile' => '@runtime/logs/error.log'
],
],
],
You should not use debug toolbar in production.
I only want to use the debug-module for analysing the errors logged in /runtime/logs/app.log
Because the debug-module displays the erros very nice 
To look into the app.log is not comfortable, because it is just plain text. How do you analyse the app.log file in production-mode?!
Well, personally I’m using https://rollbar.com/ for production logging. Debug toolbar can’t read logs since it needs more info.
