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.

Pros

"We are seeing a return on investment from using Gremlin Reliability Management Platform because we are getting less production issues by thirty percent, as I mentioned earlier, making it a great investment."
"Since using Gremlin Reliability Management Platform, we were able to reduce the incidents by six percent after conducting our limited experiments, and we were also able to increase the uptime from ninety-eight to ninety-nine, which represents a one percent increase in uptime."
"The Enterprise Reliability Platform has positively impacted my organization as it has significantly increased the efficiency and reliability of our systems."
"Gremlin Reliability Management Platform is amazing with the reliability score, providing built-in Chaos Engineering experiments that you run on your service to receive a reliability score along with insights on the issues and risks present in your service that you can examine and work on."
"Using Gremlin Reliability Management Platform has raised more than fifty percent of the reliability of the infrastructure."
"The most useful feature of this solution is tracking. When the application's traffic has been monitored it is taken from that particular application and analyzed. It is then given a live session of that particular user. For example, if you are using your bank application to do some kind of transaction, everything that you do can be tracked by that application."
"If you have an old-fashioned infrastructure with data center servers then this is a good solution for you."
"The technical support is good at resolving issues."
"Real User Monitoring tools help proactively identify problems before they become critical by monitoring thresholds. There is a threshold and an SOA threshold."
"It offers near-real-time analytics, which is helpful."
"Real User Monitor has improved our productivity."
"The Real User Monitor, with its transaction and synthetic transaction monitoring, is the typical classic in APM cases when the customer would like to do transaction monitoring. Micro Focus scores better where the underlying infrastructure management is also covered by Micro Focus tools."
"Real User Monitor has made it easier to drill down and see how users connect to and use our website."
 

Cons

"Gremlin Reliability Management Platform can be improved as the pricing is a bit expensive and the learning curve for beginners is a bit difficult."
"I think that it will be important to have resources to perform self-directed studies on Gremlin Reliability Management Platform as an improvement."
"I think Gremlin Reliability Management Platform can be improved by integrating with more AWS services or GCP services."
"There have been some issues with customers implementing this solution and with login errors, which could be areas for improvement."
"Real User Monitor needs to cover more protocols to provide more in-depth information. It could also be better at monitoring voice-related traffic."
"Real User Monitor needs to cover more protocols to provide more in-depth information. It could also be better at monitoring voice-related traffic. There is currently no visibility in that channel."
"Some issues with login errors."
"We would like to see support for non-Windows environments."
"One final complaint I have is that the roadmap from the vendor is not clear, which makes it less attractive to some customers."
"When we want to monitor our encrypted traffic, this product doesn't work because our cipher is not supported."
"Customer support needs to improve by bringing in more people who are knowledgeable about the tool, as there are very few left."
