Scout APM has proven to be a valuable tool for monitoring and optimizing application performance. Users have successfully utilized Scout APM to identify and diagnose performance bottlenecks, improving response time and enhancing the overall user experience. By tracking performance metrics such as transaction traces, CPU usage, and error counts, Scout APM provides insights into the root cause of issues, allowing users to pinpoint slow-running parts of their applications. Additionally, Scout APM's call aggregation feature offers detailed metrics and backtraces for database calls, external HTTP requests, and libraries, aiding in load testing and capacity planning. With its ability to identify performance peaks outside business hours and continuously monitor performance, Scout APM proves instrumental in solving issues and finding consistent bottlenecks. Overall, users find that Scout APM helps optimize app performance, reduces hosting costs, and provides historical performance monitoring for benchmarking purposes.

Intuitive and User-Friendly Interface: Users have praised Scout APM for its intuitive and user-friendly interface, with multiple reviewers highlighting this aspect. The interface is described as easy to navigate, allowing users to quickly obtain insights and reports about application performance without the need for extensive documentation.

Effective Performance Monitoring: Many users appreciate Scout APM's ability to compare performance over time and monitor the impact of changes. This feature allows them to identify performance bottlenecks easily. Additionally, the N+1 queries callouts feature has been particularly helpful in pinpointing and fixing these bottlenecks.

Seamless Integration Process: The seamless integration process of Scout APM is highly valued by users. They find it easy and straightforward, enabling them to quickly start receiving useful statistics about their applications' performance.

Traces Lack Detail: Some users have mentioned that the traces in Scout APM are sometimes not detailed enough, lacking information such as SQL queries or specific lines causing issues. This has been a concern for several reviewers who rely on comprehensive trace details to effectively troubleshoot and optimize their applications.

Steep Learning Curve: Users have expressed that the features provided by Scout APM require an intermediate level of experience to work effectively on the platform. While the platform offers powerful functionality, it can be overwhelming for new users and may require a significant learning curve to fully utilize its capabilities.

Limited Time Window: Users have found the time window period in Scout APM limited and a little hard to use. Additionally, they would like to be able to access data older than 30 days in the UI of Scout APM. Having a longer data retention period would allow for better historical analysis and trend identification within the application performance monitoring tool.

Based on user reviews, Scout APM has received several recommendations. The top three suggestions are:

  1. Users recommend trying out Scout APM, particularly for mid-size companies. They have found it valuable in monitoring and resolving performance issues over the long term.

  2. Another common recommendation is to set up Scout APM to gain better visibility into app performance and reduce response time. Users appreciate its ease of use and the insights it provides for optimizing code, identifying N+1 queries, and improving memory and time usage.

  3. Many users highly recommend Scout APM for Rails or Python apps due to its simplicity and powerful features. They consider it an essential tool for significant application performance improvements.

While users generally praise Scout APM for its ability to monitor app performance, some suggest that the user experience could be improved to enhance problem identification. Additionally, a few users recommend using another system to aggregate data or record averages for longer-term performance monitoring alongside Scout APM.

Scout APM helps our engineering team to monitor our main Rails application which is a Monolith hosted on the Heroku platform. It has helped to monitor and debug most of the outages, degradation of response times, or memory bloats for the past 4 years with a great amount of accuracy. It has helped us to do this in our web and background processes.
  • Rails instrumentation
  • Segmentation by controllers and sometimes methods
  • Detecting low performing endpoints
  • Errors (is a new functionality but I didn't get well how it can replace rollbar for example).
  • Usage measuring: In some cases is easy to get "disabled" due to a peak of bad requests.
  • Editing app's names
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).

  • Speed to solve incidents
  • Easy to monitor new endpoints or deployments
  • Easy to monitor background jobs (like sidekiq)
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
