Utilizing data monitoring capabilities and scripting potential to optimize system management
I frequently program functions with PowerShell, and although Bash could be used, my specialization is in PowerShell. Two of us focus on programming in PowerShell for infrastructure optimization. I set up a dedicated server to run scripts every hour, generating files for Checkmk output. However, Checkmk does not allow running scripts at varying intervals. I am working on this in the raw version of Checkmk.

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.

"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."
"The Enterprise Reliability Platform has positively impacted my organization as it has significantly increased the efficiency and reliability of our systems."
"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 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."
"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."
"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."
"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."
 

Cons

"Checkmk does not work too easily with the PowerStore. I use a PowerShell script as Checkmk runs on Linux and a Windows system, connecting with the Checkmk agent."
"Sometimes we receive alerts, and it can become annoying when you acknowledge an alert. It is very clunky when you acknowledge the alert. The process is not very intuitive, and there are instances where it feels a bit cumbersome to acknowledge an alert."
"In Checkmk, the documentation can probably be improved a bit more."
"The initial setup is a bit complex."
"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."
"Checkmk does not allow running scripts at varying intervals."
"If an alert is generated for a specific pattern in the log, and if Checkmk catches that log, it will stay there even after the alert is resolved."
"The main challenge for us is that we're moving from Nagios to Checkmk, and we're still getting used to the new way of working."
"If you really look at the cost-benefit visibility, it is not very evident by using Gremlin Reliability Management Platform."
"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."
"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."
"Gremlin Reliability Management Platform can be improved as the pricing is a bit expensive and the learning curve for beginners is a bit difficult."
