Log4j is perfect to use in applications where you suspect you have a need to troubleshoot the application in a running environment and don’t know in advance exactly which parts of the application you want to troubleshoot.

I have not used any other software but I have gone through demos of others and LogDNA gave us everything we needed at a fair price and with a great UI on the back end. It was not even a question of which software to choose. They are a great team.
