DevOps & Mlops Engineer at a printing company with 1-10 employees
More than scalability, I thought about availability because it is a really important thing of the architecture tools.
Dev Ops To Development (IT)
The scalability of Gremlin Reliability Management Platform depends on the scalability of the underlying infrastructure that we are hosting it on.
Senior Software Engineer at a sports company with 10,001+ employees
We have reached maximum capacity in our tier, and extending capacity has not been cost-effective from Splunk's perspective.
Senior Principal, Enterprise Architect at a computer software company with 201-500 employees
I would rate the scalability of Splunk AppDynamics as a nine out of ten.
Digital Performance Tester at Amdocs
I assess how Splunk AppDynamics scales with the growing needs of my organization as good, since we are growing and adding more servers.

Splunk AppDynamics is superior to any alternative, including Dynatrace.
Technology lead at Infosys
 

Room For Improvement

Enhancing Gremlin with AWS, GCP, machine learning integration and resources can improve usability, despite high cost and complexity.
Splunk AppDynamics struggles with UI complexity, support delays, integration issues, high costs, and requires better AI and user-friendly reporting.
I think it would be useful to have some integration with Splunk or other log collectors, or maybe in the future, the ability to link Dynatrace or any other observability platform.
Dev Ops To Development (IT)
If we can integrate it with natural language, could we talk to Gremlin Reliability Management Platform and have it configure some of the basic settings so that non-technical persons can also work on Gremlin Reliability Management Platform-like tools?
DEVOPS specialist at a media company with 10,001+ employees
The user interface is great, the integration is smooth, and Gremlin Reliability Management Platform has a fantastic support team that helps us a lot in many cases.
DevOps & Mlops Engineer at a printing company with 1-10 employees
Splunk AppDynamics does not support the complete MELT framework, which includes metrics, events, logging, and tracing for the entire stack.
Senior Principal, Enterprise Architect at a computer software company with 201-500 employees
AI could provide more insights for annual or half-yearly reports and forecast future changes in the asset landscape.
Senior Delivery Manager at GE Vernova
If AppDynamics could develop a means to monitor without an agent, it could significantly improve application performance and reduce potential problems.

Setup Cost

Splunk AppDynamics is costly with variable pricing influenced by complex licensing, offering value for enterprises despite challenges.
It is not so cheap, but it has very powerful features.
Dev Ops To Development (IT)
My role does not incur costs for us since we have an NFR for Gremlin Reliability Management Platform that we can use in our case.
DevOps & Mlops Engineer at a printing company with 1-10 employees
We completed a three-year deal for Splunk and for AppDynamics, which costs millions of dollars.
Development Operations Engineer at a retailer with 10,001+ employees
Overall, I consider Splunk AppDynamics an expensive product; it's very expensive.
Manager, System Scom at Handelsbanken
The resource team finds the best prices, ensuring that Splunk AppDynamics is an acceptable option for the end user.
Senior Delivery Manager at GE Vernova
 

Valuable Features

Gremlin Reliability Management Platform enhances system performance with prebuilt tests, automated scheduling, and a user-friendly dashboard for improved uptime.
Splunk AppDynamics offers real-time monitoring, end-to-end visibility, and proactive performance management, enhancing business resilience and reducing downtime.
There are really two pathways along: fewer incidents because with Gremlin Reliability Management Platform, we can make every part of the infrastructure more solid, and less downtime because we can test more architectures and then things like how to put in high availability clusters.
Dev Ops To Development (IT)
The best feature that Gremlin Reliability Management Platform offers for me is the prebuilt reliability test; I think that is the best feature along with the automated scheduling.
DEVOPS specialist at a media company with 10,001+ employees
One of my best features of Gremlin Reliability Management Platform is the built-in chaos experiments, which gives you the reliability score of your service.
DevOps & Mlops Engineer at a printing company with 1-10 employees
We have multiple tools, but end users prefer to use Splunk AppDynamics because their portal navigation is very simple and clear.
Back office at Reliance Industries Ltd
The real user monitoring and digital experience monitoring effectively track actual user experience with the applications, including page loading, interaction time for both desktop and mobile applications.
Regional Director at iSecureMind
This is the best feature because, although you can't monitor a whole application at once, Splunk AppDynamics gives you the option that if there is any failure—simple failure regarding anything set up as per our use cases—you will get an alert.
Technology lead at Infosys

Senior Software Engineer at a sports company with 10,001+ employees
Chaos experiments have revealed weak points and now provide controlled cost-saving tests
The best features of Gremlin Reliability Management Platform are the safe failure injection, which is crucial as we can simulate the failures in a manner that we know these are just dumping tests and not the actual issues. Whether it is the CPU spike or the memory exhaustion, or the network latency, or the server shutdown, server shutdown is one of the most favorite features that I have in Gremlin Reliability Management Platform. The controlled blast radius is another standout feature. The controlled blast radius feature has helped my team in that we actually wanted to target only one specific container, our Docker containers that we deployed. It helped us to conduct tests in a very specific, isolated manner instead of launching a larger test or focusing on hundreds of servers at a time, resulting in very limited impact. Since ours is a very small team, we do not want to impact other servers. This controlled blast radius helped us to only focus on our servers and not impact any other team. Gremlin Reliability Management Platform has positively impacted my organization because before Gremlin Reliability Management Platform, we did not even know how to conduct these chaos engineering tests. We heard about it, but we had no idea of how to do something of that nature. If there are ten servers, ten systems in our architecture and if suddenly something goes down, nobody knew what would happen next. We did not even know how to simulate these types of tests. This lack of confidence has been mitigated by using Gremlin Reliability Management Platform. Now we can confidently test and see which system is the most critical. If this goes down, what happens? How much business valuation are we going to impact? How much loss are we going to incur? All of this is now clearly visible and transparent. Since using Gremlin Reliability Management Platform, we were able to reduce the incidents by six percent after conducting our limited experiments. We were also able to increase the uptime from ninety-eight to ninety-nine, which represents a one percent increase in uptime.

Real-time monitoring has improved our banking API performance and supports detailed business transaction analysis
The real-time monitoring is what we can see for anything that is needed in terms of CPU, memory, or the connections or the sessions related. It's real-time monitoring of performance of each of the components, which is what we need and use all the time. It's highly effective, I would say. Infrastructure visibility, transaction monitoring, to check the actual user experience in terms of the response time, MRT and all those things. We do the component monitoring like the API performance and the connections and all those things, but we also do the business process monitoring and business transaction monitoring.
