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.

Easy to use, and it's possible to customize the product as per the needs we may have but average multi-tenancy aspect

It's supported by the community. We use Icinga, which is not part of the Open-Source platform but is wrapped into a commercial solution from another provider, a local provider in Italy. Icinga is an open-source platform, so it is supported by the community. It's quite easy to use, and it's possible to customize the product as per the needs we may have. So it's not expensive, and it's quite a general purpose. We can easily monitor any kind of infrastructure we encounter. The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated. The alerting is the same as any other monitoring platform. It's not a "wow" feature that has changed our lives, but it's perfectly adequate.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

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

"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."

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

"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."

"The Enterprise Reliability Platform has positively impacted my organization as it has significantly increased the efficiency and reliability of our systems."

"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."

"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 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."

"I like the ability to amend and adjust things really easily, which is useful in a case where you could make it auto-discover and then set a template to say all of these applications or servers under this template have an automatic threshold set that you’d set up manually."

"This solution has a self-healing handler where if the service is down, it is automatically restarted."

"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."

"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."

"Icinga2 was designed to delegate, distribute and balance tasks between several nodes."

"We have found the solution to be stable."

"The most valuable feature is one that not many are even aware of, as Icinga has a self-healing event handler where if the service is down, it is automatically restarted, and you can configure the handler to take action after the critical alarm without human interaction."

"I use it for monitoring infrastructure and it was very good for that issue."

More Icinga pros

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 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."

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

"The tool currently fails to provide notifications to users."

"Scalability is problematic. If you have a stable environment it's good, but if the environment is growing, I had some problems with Icinga."

"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."

"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."

"The connection between Icinga and Icinga Web."

"Icinga’s automation could be improved."

"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."

"The installation and configuration are very complex."
