A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility

We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

Provides comprehensive management with AI-driven insights and predictive analytics for seamless IT operations

The major improvement recommended for Nutanix Prism is more multi-cloud cost optimization. It shows performance and usage but is limited in detailed cross-cloud cost analysis. Improvement is needed for deeper FinOps-style ML insights that compare costs between on-premise, AWS, Azure, etc. Enhancements for the current mobile version of Prism are necessary as its functions are limited. Full mobile native control with real-time alerts and AI suggestions are required for one-click actions. Better integration with third-party tools and predictive maintenance for hardware is needed; currently, the focus is on VM and storage, not hardware life cycle. Predictions for node-level hardware failures or SSD wear-out, fan sensor alerts in advance are essential improvements, as is AI-based security threat detection focusing on unusual login patterns such as ransomware behavior or privilege escalations.

Quotes from Members

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

Pros

"It's very easy to manage and monitor it."

"Being open source lets us customize it for our monitoring needs, saving us money."

"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."

"It also does a good job when it comes to optimizing performance with machine learning and AI. It's able to identify the VMs that are constrained and not constrained, and which ones are "bully" or not. It gives you a recommendation based on your usage. It learns your user environment."

"The feature that stands out for me is the simplicity and ease of use. That is what comes to mind when I think about the Prism console. You don't need to be a core technical person to manage a cluster. Everything is available in the console itself."

"The Clone and Snapshot features are two of the most valuable aspects of the solution for our organization. Rather than simply one-click automation the Snapshot and reverse Snapshot are great."

"For me, the speed of cloning virtual machines and the hyper-convergence feature are the most valuable aspects of the solution."

"Its scalability is valuable. It's scalable and fast."

"The solution is a high-performance platform that effectively handles three-layered issues like SA and network fiber cables."

"Because in my role I create a lot of reports, it is very handy to be able to show the customer, "This is your cluster. At the moment, you are using this much CPU, this much RAM, and this much storage." I can give them information on what they're using, how many VMs, and the amount of data they're using."

"Nutanix Prism is mainly used for our daily operations, similar to VMware."

Cons

"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."

"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."

"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."

"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."

"The main area where an improvement could be made would be the pricing."

"The replication we have does not have any backup systems built-in. We have to separate license records for backup, like onboard. We would like to have this in a future release."

"The VM backup could be better, and its licensing could be better. We have had some licensing issues with Nutanix Files. The default license should be 1 TB or more. Currently, for Nutanix Files sharing, we can only use 500 Gigabytes."

"It doesn't integrate very well with any backup solution."

"The three clusters we have at our remote offices are just one-node clusters. If there were an easier way to upgrade items such as the BIOS, SATA drives, the BMC, et cetera, on those, that would be helpful."

"Perhaps the interface can be more intuitive."

"The licensing cost has room for improvement."

"Nutanix does not support all of the Linux distributions, so we have to use VMware in some cases."

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."

"Microsoft Hyper-V is free, whereas Nutanix isn't. Nutanix isn't so expensive. VMware is more expensive than Nutanix, but with VMware, there aren't many licenses, whereas, in the case of Nutanix, we need to upgrade the license periodically. It could be every three years or five years. It depends on your license. There are no costs in addition to the licensing fee."

"...we use it for small and medium-sized businesses. For those companies, Nutanix is too expensive, it's for bigger businesses..."

"Nutanix Prism is priced better than some of the competing solutions."

"Nutanix have bundles for pricing. On a single bundle, we get everything including vSAN or VMware and there are no additional costs. It is just a single license that is needed."

"The licensing aspect is painful. We are told, "This is when you have to renew. This is the serial number and the part number," et cetera. But it's difficult to know where something belongs unless you dive into the portal and search in multiple areas for a particular serial number."

"Nutanix Prism is quite an expensive solution compared to VMware."

"As far as pricing goes, it's competitive for what you get. There are probably less expensive hyper-converged solutions, but I don't think they're as mature or have the feature set that we get with Nutanix."

"This product is cheaper than using VMware."
