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

"Gremlin Reliability Management Platform has impacted my organization positively as it helped a lot and reduced our failures, allowing us to find critical pinpoints in our application that had existed for three to ten months and led to too many improvements, reduced downtime, and a smoother experience for our application on AWS."

"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."

"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."

"Gremlin Reliability Management Platform has positively impacted our organization by making outages less frequent and improving recovery time significantly, resulting in fewer complaints on the customer success side and overall optimization of our DevOps process."

"More than anything, we fix failures even before they occur, which is basically proactive risk detection and risk mitigation."

"Using Gremlin Reliability Management Platform has raised more than fifty percent of the reliability of the infrastructure."

"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."

"We use RUM and BSM and so far it has been really good at getting real user transactions from a real user monitor and then tying it to a BSM single view dashboard, where we get the whole realistic picture."

"Real User Monitor has improved our productivity."

"It is a good product."

"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."

"This solution is very reliable; it's stable."

"We found this to be a stable product."

"If you have an old-fashioned infrastructure with data center servers then this is a good solution for you."

"Real User Monitor has made it easier to drill down and see how users connect to and use our website."

Cons

"I think that it will be important to have resources to perform self-directed studies on Gremlin Reliability Management Platform as an improvement."

"If you really look at the cost-benefit visibility, it is not very evident by using Gremlin Reliability Management Platform."

"I think Gremlin Reliability Management Platform can be improved by integrating with more AWS services or GCP services."

"I rate it an eight because we are still using it on a trial and error basis, and the pricing could be optimized for better cost visibility and ROI tracking."

"Gremlin Reliability Management Platform can be improved as the pricing is a bit expensive and the learning curve for beginners is a bit difficult."

"If it is a standalone solution, however, I would not recommend Micro Focus."

"Recently we have been facing some stability issues."

"Most of the dashboards require a lot of configuration. We are not happy with the dashboard."

"There have been some issues with customers implementing this solution and with login errors, which could be areas for improvement."

"Everybody is moving away from traffic and installing agents on the application to do the job, but Micro Focus is using traditional ways to collect the traffic. They should change their architecture completely."

"I have to say that I am very disappointed with this solution. It's very heavy, and it is a nightmare to deploy and maintain."

"The solution's technical support presents a lot of issues with too many delays."

"We would like to see support for non-Windows environments."
