Room For Improvement

Prometheus Group's setup and query language are challenging; improvements needed in UI, documentation, integrations, security, error handling, and pricing.
Splunk AppDynamics requires improvements in interface design, setup, mobile compatibility, real-time monitoring, and modern technology support.
Splunk AppDynamics provides an end-to-end view of the application but misses the infrastructure part, which is crucial.
If AppDynamics could develop a means to monitor without an agent, it could significantly improve application performance and reduce potential problems.
 

Setup Cost

Prometheus Group is cost-effective due to its open-source nature, preferred over more expensive solutions like New Relic or Datadog.
Enterprise users find Splunk AppDynamics pricing complex and costly, requiring careful assessment and negotiation for better deals.
Prometheus is cost-effective for me as it is free.
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.

Splunk AppDynamics offers comprehensive observability, real-time monitoring, and efficient transaction analysis across development and production environments with minimal overhead.

What I like the most about Splunk AppDynamics is the end-to-end observability for the application, along with traces.
The feature that I appreciate in AppDynamics Browser Real-User Monitoring is the intuitive and user-friendly dynamic mapping it creates for workflows.
The real-time feature provides me with insights into what's happening.

MuhammadAzhar Khan - PeerSpot reviewer
Free to use and provides valuable monitoring capabilities
Prometheus is a scalable and flexible tool that I can deploy on any cloud platform. It is free to use and provides valuable monitoring capabilities. It allows me to save money by avoiding costs associated with AWS native services like CloudWatch or Amazon Prometheus. The ability to deploy on any cloud platform or environment, including Kubernetes, is a major advantage.
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.
