Sentry provides engineering teams with tools to detect and solve user-impacting bugs and other issues.
To me, it's the best APM out there for a Rails application. It is really easy to set up, configure and start debugging any kind of bad-performing endpoint. We have solved issues going from High Response Time to Memory Leaks/Bloats. All of this can be achieved even if you are hosting your app in a PaaS like Heroku. (Where sometimes is difficult to install an agent like in other vendors).
Great for standard web application performance monitoring, analytics and error reporting. Shows line level code errors, gives insight into performance issues (plugins, API issues, etc.). Automation and scheduled scanning in production gives client visibility into 'after deployment' value. Also lets a relatively small number of developers keep tabs on a handful of different site/applications without needing a bunch of tools. The UI is pretty complicated and can be overwhelming for new users. Documentation could be better for the learning curve,
Great web interface. Lots of data available in a really clean format, with filtering options and more.
Per-user exception tracking. User is complaining about something being broken? Look up their account ID in Sentry and you can see if they've run into any exceptions (with device information included, of course).
Source map uploading. Took a little while to figure this out but now we have our deploy script upload sourcemaps to Sentry on each deployment, meaning we get to see stack traces that aren't obfuscated!
Very generous free tier – 10,000 events per month. We're nowhere near that yet.
We have preferred Scout APM over Datadog due to: - Easy to configure and install on Heroku Platform (Datadog's agent can give some trouble when installing it on Heroku's Dynos) - Easy to monitor normal behavior and be actionable on endpoints who are out of normal - It has an easier pricing which facilitates to make predictions on budget
We used Rollbar but didn't like the configuration its not easy. And also doesn't support wide features like Sentry although its a cheaper option but doesn't have the dash-boarding like Sentry and its was not easy to integrate webhooks for different purposes. Somehow many people in company where not able to understand Rollbar dashboard who were very much used to Sentry.
We had to take it down later due to internal reasons and majorly because of cost-cutting process
If someone has a unstable system and have no way to figure out what to do, can use sentry at least temporarily along with some other APM to fix their system faster
