Sentry vs. Splunk IT Service Intelligence (ITSI)

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 ITSI is a great tool (and toolbox) for combining together numerous and varied monitoring regimes to bring more holistic analysis and reduce alert fatigue. By leveraging the Splunk ITSI service and KPI modeling regime, ecosystem telemetry can be turned into a more reliable, clearer, high-level perspective on the current state of your components and services.

• 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.

• Monitor hundreds of IT services by continuously tracking thousands of KPIs in a scalable way.
• Quickly identify problem areas by a combination of default visualizations and ability to create custom dashboards.
• Extremely configurable to effectively monitor nearly any KPI imaginable from Splunk.

• 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

• ITSI really needs a robust splunk log ingestion infrastructure at its core
• ITSI requires a great engineering team to build out the automated discovery and topology
• Unless you use an API to build the topology, the view can quickly become static

We have replaced our monitoring platform with Splunk & ITSI, and with the success, it's seen at our organization thus far we would be hard-pressed to pivot to another tool. Frankly, our business partners and application teams love Splunk & ITSI.

During POC, pre-planning, and implementation, we have had interactions with numerous folks at Splunk. Everyone from sales & engineering to markets analysts to specific IT component SMEs, and a small professional services engagement to get started. They have all been exceptionally helpful and go above and beyond the call of duty. They actively reach out to ensure success is being realized and find ways to help proactively, instead of having to simply open support cases with the vendor.

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 has raised itself as a platform not just as a tool unlike other products in the market. If I talk about Moogsoft it also has similar capabilities but Splunk ITSI has more visibility and its GUI is making a different impact on the users. ServiceNow and Splunk are equally capable products however Splunk seems to have more tech-savvy people tools than ServiceNow.

• 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 ITSI has reduced the number of alerts exposed to our Network Operations Center by 100x while increasing the context around outages.
• Splunk ITSI has increased the accuracy of our incident detection by leveraging the Event Analytics system to weigh the behavior of the many characteristics of each component together instead of independently.
• Splunk ITSI has reduced our incident MTTR (mean time to restore) by detecting issues faster, presenting them more clearly, and surfacing the salient details about the underlying issue.
