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.

The open architecture is easy to extend and enhance

Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas. They could improve their management console's ability to monitor large environments could be improved. For example, SNMP management is only partially integrated into the management console.

Cons

"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."

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

"It would be useful if Pandora FMS included an ISO image (or «software appliance») for each big company that leases virtual private machines (VPS), just like in AWS."

"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."

"In the future, we may have double the number of devices, and we do not want to have any issues with performance in the data display."

"We would like the real-time monitoring of an interface to be improved within this solution."

"A nice feature in the next release would be an automation module to run workflow actions."

"I find that this software is resource heavy, and demands a lot of processing capacity."

"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."

"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
