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.

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.

Quotes from Members

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

Pros

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

"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."

"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."

"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."

"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."

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

"Infrastructure monitoring is the most valuable feature."

"The product's ability to monitor systems and applications and send alerts and create support tickets are the most valuable features of the product."

"System health check monitoring and email alerts after reaching threshold limits."

"It's a very flexible product so you can run a script out of it, even straight out of the box."

"It can monitor over a 100 technologies with built-in solution templates."

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

"It's user-friendly and it's very good at monitoring the infrastructure and the applications."

Cons

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

"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."

"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."

"Micro Focus SiteScope is a little slow to load when I go to load it up, and it's not as intuitive as some of the other programs, such as SolarWinds."

"They should provide more templates for new vendor devices."

"We think that AppDynamics will do this in a more satisfactory way for us and we do not have this feature with SiteScope."

"It may lack some features other products in the category have like more detailed transaction tracking."

"We have four or five data centers around North America where we have it deployed into a single or a two-server primary backup type of deployment. All those are made available under a single GUI provided by Micro Focus that allows you to put them all together. A room for improvement would be an appliance or a server that would manage all of our other servers so that I don't have to remember to log on to all different servers and data centers. I could manage them from a single location."

"I would be very interested in having transaction traceability included in the product, to give us a better view of what is really going wrong in a particular method and action."

"Licensing is a little steep. Since HP's acquisition of the product, licensing is done on a points-per-monitor basis, and with literally hundreds of nodes and application monitors available, costs can get steep."

"The interface of OpenText SiteScope needs improvement. It has a Java-based interface, which is slow and could be simplified for better usability."

Pricing and Cost Advice

Information not available

"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."

"Licensing is a little steep."

"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."

"Depending on your requirements, there are two licensing models available. A simple point model, or an endpoint model."

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

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

"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."
