I know we can apply different message levels to different log routes, but I still wanted to see all the other messages.
So, I decided to add *two* CWebLogRoute entries to my main configuration:
.... ,'components' => array( 'log' => array( 'class' => 'CLogRouter' ,'routes' => array( array( 'class' => 'CWebLogRoute' ,'levels' => 'mine' ) ,array( 'class' => 'CWebLogRoute' ) ) ) ) ....
This causes two "application log" boxes to appear at the end of the web page, in the sequence listed above, using the defined levels (the second array has no 'levels', so displays all log entries).
Then, wherever I use Yii::log(...), I specify 'mine' as the level. This causes my log message(s) to appear in both "application log" boxes. The first log box shows only my messages with a level of "mine", and the second log box shows all messages, with mine (or "mine", if you will) appearing in the relevant position in the sequence of events.
Sorry if this is obvious to the masses, but I thought I could make my own small contribution in case there are other noobs like me out there
