Room For Improvement

Gremlin could improve through AI-driven analysis, better user onboarding, expanded service integrations, enhanced UI, and additional learning resources.
NETSCOUT Network & Application Observability requires interface simplification, better integration, enhanced analytics, reduced costs, and improved user experience and documentation.
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) at a non-tech company with self employed
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?

Valuable Features

Gremlin enhances efficiency with test suites, fault injection, risk detection, and reliability insights, boosting uptime and customer satisfaction.
NETSCOUT Network & Application Observability provides comprehensive network analysis, offering visibility and quick issue resolution through its user-friendly interface and robust features.
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) at a non-tech company with self employed
We fix failures even before they occur, which is basically proactive risk detection and risk mitigation.

Ravi Konduru - PeerSpot reviewer
VP Global at a tech vendor with 10,001+ employees
Proactive failure testing has increased confidence and reliability across complex microservices
There are certain areas where I think Gremlin Reliability Management Platform can improve. I would certainly add features related to AI and GenAI for recommendations. While dependency identification works well seamlessly, deeper dependency intelligence is lacking. When you have deeper dependencies, reliability management can struggle with identifying those deeper dependency intelligences. Having the intelligence to deeply analyze dependencies will be very helpful. Regarding reliability scores, while those scores are good, having more actionable reliability scores is something I would recommend adding to the existing system. Initially, when I started with Gremlin Reliability Management Platform certification programs, I completed two certifications with Gremlin—one professional and another practitioner. While that certification has helped me, an easier onboarding and learning curve for bringing people into this program can be adjusted. That is one current gap I see. If you really look at the cost-benefit visibility, it is not very evident by using Gremlin Reliability Management Platform. If Gremlin Reliability Management Platform could help realize that and bring in visibility regarding the cost versus the benefit, that is the reason I provide a score less than ten. From a standpoint of simulating complex real-world failures, I believe there is still a gap concerning gap identification. Currently, Gremlin Reliability Management Platform mainly focuses on infrastructure-level failures and does not really simulate business logic failures, data corruption scenarios, or potential failures across regions. One of the key elements needing improvement with Gremlin Reliability Management Platform is the limited team workflow integration I see in my organization. Collaboration and limited team workflow integration are areas I would highlight as needing improvement.

Monitoring has improved bandwidth insights and application diagnosis but setup and costs still need work
They need room for improvement about the spare parts. There are shortages in Egypt in their stock. We tried to make RMA for specific parts, and it took a long time. Comparing this to a vendor like Cisco, who provides any component next business day, NETSCOUT nGeniusONE took a long time. This needs more improvement. I believe it is expensive. They need to reduce its budget a little bit. Comparing to other solutions, it is very expensive.
