LogDNA is great for all your apps to log activity. Not much more to say about it. It does what it sets out to do. Everyone in our company uses our app so it's nice when someone is having an issue and we need to dig deeper into what they were doing and LogDNA helps in those scenarios.
SolarWinds Papertrail is great if you have multiple separate applications and you want to be able to view and search all the logs in one place. It also works well for alerts based on certain keywords in log entries (for example, ERROR, WARN, etc.) Since only the first four weeks of logs are searchable in Papertrail, it may not work well for use-cases where much older log entries need to remain searchable.
The colors are ugly, both the dark and light theme. Needs better contrast and color combinations. It's also weird that dark mode has white dropdown menus on the filters.
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's extremely easy to use. I and new colleagues have never had any issues configuring this tool or setting it up, it works almost out of the box with very simple instructions to follow to configure it to our own environment. I would highly recommend it on that ability alone.
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.
I honestly have never had the need to use the support team, as we have not run into any issues so far. If we did however, judging from how the tool itself works, I don't doubt that the team would provide excellent support for any issues that we may possibly run into.
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.
I selected SolarWinds Papertrail because it was cheap and already provided precisely the integration surface required by the Heroku stack. It probably provided the least number of 'useful' features (out of the bunch) due to the nature of my logs and the post-mortem updates that were required to make them usable.
