Proactive failure testing has increased confidence and reliability across complex microservices

There are certain areas where I think Gremlin Reliability Management Platform can improve. I would certainly add features related to AI and GenAI for recommendations. While dependency identification works well seamlessly, deeper dependency intelligence is lacking. When you have deeper dependencies, reliability management can struggle with identifying those deeper dependency intelligences. Having the intelligence to deeply analyze dependencies will be very helpful. Regarding reliability scores, while those scores are good, having more actionable reliability scores is something I would recommend adding to the existing system. Initially, when I started with Gremlin Reliability Management Platform certification programs, I completed two certifications with Gremlin—one professional and another practitioner. While that certification has helped me, an easier onboarding and learning curve for bringing people into this program can be adjusted. That is one current gap I see. If you really look at the cost-benefit visibility, it is not very evident by using Gremlin Reliability Management Platform. If Gremlin Reliability Management Platform could help realize that and bring in visibility regarding the cost versus the benefit, that is the reason I provide a score less than ten. From a standpoint of simulating complex real-world failures, I believe there is still a gap concerning gap identification. Currently, Gremlin Reliability Management Platform mainly focuses on infrastructure-level failures and does not really simulate business logic failures, data corruption scenarios, or potential failures across regions. One of the key elements needing improvement with Gremlin Reliability Management Platform is the limited team workflow integration I see in my organization. Collaboration and limited team workflow integration are areas I would highlight as needing improvement.

Proactive monitoring has reduced response time and has improved capacity planning accuracy

Regarding areas for improvement, there may be minor issues, but I have not faced any significant issues with OpenText SiteScope because I have a team that uses this product daily. As a monitoring dashboard user, I do not have any negative feedback. A feature that could be added is direct integration with a ticketing tool, as it would help operation teams directly detect alarms and alerts happening in our infrastructure. Direct integration with a ticketing tool such as Remedy would be a good feature. OpenText SiteScope has some limitations, especially with integration between OpenText SiteScope and Remedy, which must be done through middle software. There are also limitations for cloud monitoring as well as for Docker and Kubernetes.

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

Pros

"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."

"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."

"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 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."

"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."

"It's a monitoring tool that's deeply integrated with Performance Center, allowing us to put a load on it and see all the information we need, and it's an inexpensive solution."

"It's integrated with different monitoring tools, such as AppDynamics."

"I would recommend the product."

"Being able to create your monitors for monitoring your internal URLs and databases and other things like that is valuable."

"I find OpenText SiteScope itself to be uncomplicated and deserving of a ten out of ten due to its simplicity."

"Our experiences with Micro Focus SiteScope have been mostly positive as we can easily work with multiple monitors and different types of monitors pretty quickly."

"The biggest benefit I see from OpenText SiteScope is that it is a very professional tool, and it helps me greatly."

"SiteScope is very intuitive and we've been able to accomplish what we want very quickly and efficiently compared to IBM."

Cons

"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."

"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."

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

"The tool needs to support new technologies like Kubernetes. It also needs to improve scalability."

"I think that the scalability needs to be worked on a bit. We can scale fine horizontally, but we’d like to scale less horizontal and be more compact."

"Direct integration with an SMS gateway for sending critical alerts to the support SME. This will help customer investing in third party middleware solutions for SMS."

"Micro Focus Voltage SiteScope could improve by adding more features, such as cloud, APM, and DevOps monitoring."

"We'll probably remove SiteScope shortly because we've been using another monitoring tool in production. SiteScope is just not something we use very much of any more."

"If you're considering Sitescope as your sole or primary monitoring tool, I suggest you take a look around - there are better options for you."

"More out of the box Cloud integration and capabilities. Currently there's one for Amazon."

"The lack of an agent means that remote monitoring requires multiple firewall ports to be opened."

Pricing and Cost Advice

Information not available

"SiteScope licensing can be node based-or monitor-based. I would recommend for node-based licensing."

"You have to pay for their "solution templates". Other tools do not charge you for knowledge-based monitoring bundles."

"Licensing is a little steep."

"It is expensive. I don't like its licensing. I don't like anything where you have to license it by individual licenses. I'm not a fan of that, but that's just me."

"When Micro Focus Voltage SiteScope has introduced approximately eight years ago and there was not very much competition making the price high. However, when comparing the price of Micro Focus Voltage SiteScope now to other tools, they should reduce the price. It is similar to a legacy tool at this point."

"I rate the solution's pricing a six out of ten on a scale where one is cheap and ten is expensive."

"The product's pricing should be lower since there are many open-source products that can do the same job with better user interfaces. The tool's pricing is yearly and you need to pay for support."

"The pricing or licensing cost for Micro Focus SiteScope is often bundled with other things, so the cost for each individual would be difficult to calculate. Pricing could be $2,000,000 a year. My company pays for technical support because it's part of the contract with Micro Focus SiteScope. You buy the licenses, but you're also paying for the support. With Nagios, it's much more bare-bones as far as paying for licenses and the software itself, and my company didn't have to use as much Nagios support yet in one or two years because there weren't too many problems using Nagios, and it's much more cost-effective, so that's one of the reasons why my company is migrating to Nagios from Micro Focus SiteScope."
