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.
LogDNA was already setup when I started and it is offered through Heroku so that's why it was chosen. It's also cheaper I believe. Compared to Logentries, it does the same thing.
Anytime we need to make any kind of log on any platform that we use, LogDNA is well suited. It is primarily used for logging errors on our server but also used for checking issues within our iOS apps when we need to identify a critical issue that is occurring. The search feature is very very good!
It's really easy to use and powerful. But at a few times, the UI may feel sluggish, which is a bit expected, since it's displaying live stream of heavy data.
It is very very good. They are responsive and very helpful. They also take the time to walk you through the issues you are having. But honestly, it is so straightforward that you rarely need to get support from their team. They are very helpful when you do need their support though.
