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 …

Papertrail offers a much easier to use solution than Azure. We were able to integrate it into our applications without much work and the solution works robustly. Papertrail offers traditional logging services, only, but we have used Sysdig Monitor together with papertrail and …
AWS user interface and user experience is not really great, its really hard to trace logs on their console. Papertrail offers so much better user experience for us, its also very easy to setup alarm on Papertrail whenever something's gone wrong. I personally choose Papertrail …
