Sentry vs. Splunk Real User Monitoring (RUM)

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,

Splunk RUM was really helpful in identifying brute force attacks as we used Splunk query language and were able to identify how many failed login attempts were made from which country and blacklisted those IP's. Since Splunk entirely depends on Splunk query language, if there are no logs or you delete the logs you can't perform analysis, as there is no stream of live data and also it depends on how frequently your data can be indexed.

• 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.

Incentivized

• End-to-end visibility enables me to see each transaction from start to finish thereby making it easy to know where exactly an anomaly is coming from.
• They have a really kind and helpful customer support.
• Application monitoring.
• End user performance metrics.

• Alert Configuration. Would be really helpful to have multiple logical groupings within the "If" section of a single configurable alert.
• Alert Copying. Being able to copy an alert from one project to another would be super beneficial.
• Alert Tags. Better UI around how we select which tags are getting sent with each alert instead of a tiny text box.

Incentivized

• The setting baseline for AI-driven troubleshooting requires more documentation to implement.
• Room for integration with open sourced or inhouse monitoring tools.
• Required more flexibility on setting up mobile OS performance metrics.

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.

Splunk Real User Monitoring (RUM) has a much better artificial intelligence engine. It also has a much better and more intuitive user interface. Splunk RUM also allows end-to-end visibility into the front and the backend. Technical support and customer service are also much better than Goliath. Query performance is faster than Goliath.

• It helped stabilize our system in the beginning
• 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

Incentivized

• Splunk is a single platform to perform all your analysis from front end to backend and all services.
• Splunk licensing is quite costly.
• Splunk is an excellent tool for data engineering and cyber security purpose.
