Executive SummaryUpdated on May 11, 2025

Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
6.8
Sentry quickly resolves errors, boosts productivity, reduces downtime, improves user experience, and allows focus on new features.
Sentiment score
7.2
Users reported improved productivity and cost savings with AppDynamics, noting enhanced monitoring and up to 20% cost reductions.
According to errors, exceptions, and code-level details related to their application performance on a daily basis, the application development team tries to help with Splunk AppDynamics to reduce errors and exceptions, which helps the end users get application availability and feel more confident.
To understand the magnitude of it, when the company asked to replace Splunk AppDynamics with another tool, I indicated that for the proposed tool, we would need five people to do the analysis that Splunk AppDynamics enables me to do.
It's very hard to find ROI because we are currently focused only on the on-premises applications.
 

Customer Service

Sentiment score
4.9
Users rarely need Sentry support due to clear documentation, relying on community forums and receiving prompt responses when needed.
Sentiment score
7.3
Splunk AppDynamics is praised for responsiveness and support but criticized for inconsistent response times and acquisition-related service quality issues.
AppDynamics is much more helpful.
We got a contact, an account manager, to work directly with for technical support.
They help us resolve any issues raised by our team relating to operations, application instrumentation, or any other issues.
 

Scalability Issues

Sentiment score
7.8
Sentry is praised for its scalability, adaptability, and ease of use, effectively managing growth and diverse system configurations.
Sentiment score
7.4
Splunk AppDynamics is scalable and competitive but faces cost and configuration challenges in large, on-premise deployments.
It has been easy to use and configure across multiple systems, each having several environments.
We have reached maximum capacity in our tier, and extending capacity has not been cost-effective from Splunk's perspective.
I would rate the scalability of Splunk AppDynamics as a nine out of ten.
I did not find any Docker solution available with it, and a separate instance has to be installed.
 

Stability Issues

Sentiment score
8.0
Sentry is highly stable, with most users satisfied despite minor downtime, and engineers effectively leverage its performance.
Sentiment score
7.7
Splunk AppDynamics is highly stable, with occasional issues, needing enhancements in agent stability and SaaS environment during heavy use.
It is necessary to conduct appropriate testing before deploying them in production to prevent potential outages.
There are no issues or bugs with the 20.4 version; it is very stable with no functionality or operational issues.
I can rate it nine out of ten.
 

Room For Improvement

Sentry users seek better integration, analytics, customization, cheaper plans, improved UI, documentation, and advanced tracking features.
Users criticize Splunk AppDynamics for complexity, outdated tech, integration issues, challenging licensing, cost, and limited customization and support.
Integrations or single sign-on capability with Microsoft would be beneficial for securing all assets.
Splunk AppDynamics does not support the complete MELT framework, which includes metrics, events, logging, and tracing for the entire stack.
If AppDynamics could develop a means to monitor without an agent, it could significantly improve application performance and reduce potential problems.
A good integration with Splunk would be very interesting, as Splunk is a good product for logs, and that part is currently missing in Splunk AppDynamics.
 

Setup Cost

Sentry provides flexible, competitive pricing plans starting at $26 monthly, with customization options based on usage and needs.
Enterprise buyers find AppDynamics valuable but face high costs and complex licensing, requiring negotiation for better pricing.
Compared to New Relic, it provides the necessary features at a cheaper cost, especially since we moved infrastructure monitoring to Azure.
Customers have to pay a premium price, however, they receive considerable value from the product.
All these solutions at the moment are cheap, but it is like paying for insurance; you pay insurance to avoid major damage.
We find its pricing reasonable and competitive.
 

Valuable Features

Sentry offers integrations, performance metrics, error tracing, real-time insights, and supports development communication via Discord and WhatsApp.
Splunk AppDynamics provides real-time monitoring and analytics to identify performance issues, offering user-friendly operation across various platforms.
Real-time error tracking helps our Quality Assurance team easily identify the root causes of problems or bugs and promptly inform the developers about specific issues.
At this time, I focus on finding and fixing bugs.
We have multiple tools, but end users prefer to use Splunk AppDynamics because their portal navigation is very simple and clear.
The feature that I appreciate in AppDynamics Browser Real-User Monitoring is the intuitive and user-friendly dynamic mapping it creates for workflows.
What I like the most about Splunk AppDynamics is the end-to-end observability for the application, along with traces.

Abdullah Baig - PeerSpot reviewer
An easy-to-use solution that has a good dashboard, performs well, and provides flexible pricing
Sentry was easy to learn compared to New Relic and Azure Monitor. I saw some valuable input. It took us the least amount of time to see how Sentry is valuable. It took just a few minutes. Session Replay provides a replay of the recorded errors. It is a good feature. Azure Monitor does not have this feature. The error reporting is straightforward. We can see everything that we need to see. The dashboard seems pretty fine. The product performs well. We can see the user's IP addresses.
Gyanesh Rahatekar - PeerSpot reviewer
Application performance management and error resolution improved with data-driven insights
Dynatrace has multiple functions compared to Splunk AppDynamics, so Splunk AppDynamics should add those functions, which are not available as of now. Dynatrace has a universal agent that collects all information related to their CI, and if one CI has multiple languages, then there is no need to instrument multiple agents. However, Splunk AppDynamics requires multiple agents; if I have one server with multiple applications in different languages, then I need to instrument different agents for each application. Splunk AppDynamics should work with Dynatrace with one single universal agent that works with all application languages, eliminating the need for multiple implementations.
