ROI

Sentiment score
7.2
Splunk AppDynamics improved productivity, software quality, and customer satisfaction, offering significant operational benefits despite its cost.
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' customer service is responsive and customer-focused, though some users note delays and variable technical expertise.
We got a contact, an account manager, to work directly with for technical support.
AppDynamics is much more helpful.
The customer service and support are helpful and responsive.
 

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 suitable for enterprises, though some encounter configuration issues and licensing costs may impact perceptions.
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 did not find any Docker solution available with it, and a separate instance has to be installed.
We have tried it with a maximum of 500 concurrent users, and it provided all the required information.
 

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 praised for stability and reliability, with minor issues efficiently resolved, ensuring user satisfaction across environments.
It is necessary to conduct appropriate testing before deploying them in production to prevent potential outages.
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.
The Splunk AppDynamics UI is complex, lacking mobile support and integration ease, with network visibility and documentation issues.
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.
It is lacking some documentation, which is why we are always with the AppDynamics team for support to get the details.
 

Setup Cost

Sentry provides flexible, competitive pricing plans starting at $26 monthly, with customization options based on usage and needs.
AppDynamics is costly but valuable, requiring careful assessment and negotiation for better pricing compared to alternatives like Dynatrace or Datadog.
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.
We find its pricing reasonable and competitive.
All these solutions at the moment are cheap, but it is like paying for insurance; you pay insurance to avoid major damage.
 

Valuable Features

Sentry offers integrations, performance metrics, error tracing, real-time insights, and supports development communication via Discord and WhatsApp.
Splunk AppDynamics users appreciate its easy interface and features for performance monitoring, real-time alerts, and detailed diagnostics.
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.
What I like the most about Splunk AppDynamics is the end-to-end observability for the application, along with traces.
I work with the AI-powered anomaly detection and root cause analysis for troubleshooting. Users can see the error and the message with the error on the dashboard, and they can see exactly what error they are encountering.
The feature that I appreciate in AppDynamics Browser Real-User Monitoring is the intuitive and user-friendly dynamic mapping it creates for workflows.

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.
Muhammad Zeeshan Siddiqui - PeerSpot reviewer
Dynamic mapping enhances workflows that are user-friendly
One aspect that requires improvement is the agent. Without an agent, gathering sufficient information on applications is challenging. Additionally, the agent sometimes creates performance issues in production environments. If AppDynamics could develop a means to monitor without an agent, it could significantly improve application performance and reduce potential problems. Moving to an agentless solution, like what some competitors are doing, would be beneficial.
