"Among the most valuable features are the queries and reporting that allow us to look at the utilization of resources, at how well the storage is performing, and to report on which resources are being used by which business units. We can track usage across the entire environment, across applications, business units, cost centers, etc."
"Cloud Secure is definitely the most valuable feature and being able to see file level activity. It gives real-time alerting on possible ransomware attacks and provides file security review. It helps us to see if something abnormal is happening on the system before it's too late."
"Its ability to quickly inventory our resources, figure out interdependencies across them, and assemble a topology of your environment is brilliant. There is a price associated with it. Whenever you target a NetApp environment, it is included in the price but whenever you want to add different vendors, like VMware and Cisco, the price greatly spikes. Inventorization helps us a lot to visualize the environment."
"It is good for giving an overview of the systems and for tracking long-term trends. It is handy for root cause analysis, e.g. it can eliminate whether storage is the cause of an issue."
"The infrastructure monitoring capabilities are really valuable. You can just log on and see everything that is happening within an IT environment."
"The visibility that it provides is valuable. It is helping in being proactive around incident management. It is helping us to be able to get more visibility into our customers' applications so that we can assist them at the application layer. We also provide them the infrastructure from an AWS standpoint. We are able to make sure that our customers are aware of certain critical things around the analytical piece of either the network or the application. We're able to call customers before they even know about the issue. From there, we can start putting together some change management processes and help them a bit."
"We find they have a very helpful alert system."
"Its logs are most valuable."
"I have found some of the most valuable features to be the way things all come together that gives us a point of view that is useful. The panel is very beautiful and customizable."
"Having a clear view, not only of our infrastructure but our apps and services as well, has brought a great added value to our customers."
"Because of our client focus, it is easy for us to sell. This is because it is easy to use and easy to set up."
"The interface and the integrations make it so easy to connect to the cloud or to the on-premise environment."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"The installation is no problem. I've installed Nagios several times."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"The solution is pretty stable."
"The dashboard allows you to see what's going on in the overall system."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"Their pricing model needs improvement."
"In a perfect world we would have something built, right out-of-the-box, that can identify what we call "noise," and reduce the amount of data. You're presented with so much data when you first start the data collectors. For example, it brings back a lot of change rates that happen just because of standard computing, like profile changes and that sort of thing. Being able to identify things like that and categorize them and strip it down—and it probably can do that, I just haven't gotten there yet—would be very beneficial."
"There is room for improving the creating and managing or modifying of reports. That is still a difficult task to do and requires knowledge beyond the storage itself. I would love to see reporting improved so that we can create reports by dragging and dropping pieces into a report form and publish a report that way."
"When I did need support because I was having problems with the solution, the first or the second line just didn't understand it. They were providing this only on a software as a service basis. So, they were asking all the wrong questions."
"I'd like to see better pricing and more integration in the next release."
"While I like the ease of use, when compared with Tenable Nessus they could still improve their usability."
"Datadog does not have the feature where you can monitor external websites or check the SSL secure for websites."
"Could be a little more user friendly."
"Their security features could be improved. We looked at their Security Monitoring feature but it was early in its development. Datadog are just getting into the security space so I'm sure this will improve in the future."
"More pre-configured "Monitor Alerts" would be helpful."
"I'm still exploring the trial version, and it is fine. One thing that I haven't been able to figure out is how to retrieve a report. This is something that could be improved. I probably need to navigate to a place to access the reports."
"It can have an artificial intelligence component. Even though I can seamlessly look at end-to-end security, it would be better to have alerts and notifications powered by an AI engine. I am not sure if they have an AI component. We have not reached out to them or looked at it, but this is something that I keep on talking about within our company in terms of features. Such a feature would be good to have, and it would further optimize my Security Ops team's abilities."
"Open-source software is usually not user-friendly."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The installation and monitoring need improvement."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
