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.

Achieve seamless incident response with valuable monitoring capabilities and reliable alerts

There are multiple features related to OpenText SiteScope monitoring that I have found to be very useful, such as SSL monitoring. If SSL is present as a file in a server, then OpenText SiteScope is a very effective tool to monitor when that certificate expires. It provides comprehensive information related to SSL certificates and log monitoring. If any kind of required keyword monitoring is present in the log file, OpenText SiteScope has excellent functionality for monitoring. It is very easy to configure and obtain the correct information related to end-user requirements. The agentless monitoring feature of OpenText SiteScope is particularly impressive and easy to configure and gather information from. According to the operations team perspective, there is no impact related to resource management from the agentless monitoring. It demonstrates very low resource consumption related to its functionality.

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 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."

"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."

"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."

"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."

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

"The installation was a bit of a challenge. It took us almost two weeks to get it up and running."

"It should improve its integrations with various tools, especially service management tools."

"May require a dashboard for the data collected"

"OpenText SiteScope has some limitations, especially with integration between OpenText SiteScope and Remedy, which must be done through middle software."

Pricing and Cost Advice

Information not available

"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."

"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."

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

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

"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."

"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."
