We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.

Nagios XI doesn't provide scripting. For example, if we have built up multiple IPX tunnels from a base location to a data center location and want to monitor or trigger an alert if the tunnel goes down, Nagios XI does not automatically send alerts notifying us that the tunnel is down. This is a feature we want, and in the past, Nagios completed scripting for us, but it didn't work out well. In addition, Nagios XI doesn't have a feature where we can push the configuration from the server to all our devices. For example, if there are 500 devices in our network and we need to write down a simple command like a show clock or want to write the configuration, we cannot execute this command on all of our devices. We have already raised this issue with Nagios, and they told us they would speak with the BU team to see if this can be applied in the next release. If they do, it will come with an additional license. Another feature we want is the IP SLA Tracking in Cisco. For example, if our ISP connection is traversing through an L2 point, which is a layer two point, we don't have IP-to-IP communication to track those interfaces. So if we need to implement something end-to-end and the interface goes down, we should get alerts for that. And if the interface goes down, there should be specific behaviour so that our traffic can switch over from the LAN or the WAN. That is not in the current Nagios deployment, but they have advised they are working on it.

An area for improvement would be that when we need any modifications for the configurations, we need to delete the host and configure through CPM. It would be great if they could add a feature so that the existing host can be modified through XI. In the next release, I'd like them to add an option to modify the results when configuring through results.

Valuable Features

Nagios XI offers easy installation, a user-friendly interface, and low-spec server compatibility. Users highlight customization, extensive plugin availability, and script integration features. Real-time monitoring, scalability, and dashboard customization are appreciated. It provides flexible monitoring across devices and processes, with simplified network monitoring and topology visualization. Nagios XI supports creating custom APIs and writing plugins for tailored monitoring. Its open-source nature and strong community support enhance extensibility and performance reliability.

"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"We love Nagios XI due to the fact that JPS Web is very useful."

Room for Improvement

Nagios XI requires plugins for additional features, making setup complex for non-technical users. Clustering, failover, and multi-region scalability are challenging, while the interface and documentation need enhancement. Users want better integration with ticketing systems and advanced notifications. Existing dashboards are basic, and reporting processes could be simpler. Users desire more standard plug-ins and improved GUI for a user-friendly experience. External automation tools and network visibility could improve, along with simplified technical support and pricing adjustments.

"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"The user interface needs improvement."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."

ROI

Nagios XI significantly impacts time efficiency by allowing efficient monitoring, eliminating the need for manual checks. While some users do not request ROI, others note Nagios XI as critical to infrastructure and give it high ratings, although its cost-effectiveness varies. The effectiveness and efficiency benefits contribute to time savings for support teams. Observations on ROI differ based on different factors, including Datacenter, with some noting it once offered better returns.

Pricing

Enterprise users find Nagios XI's pricing competitive compared to other monitoring tools. While Nagios Core is free, Nagios XI involves annual licensing costs ranging from $3,000 to $6,000, depending on needs. Licensing is perpetual, offering good ROI, but some note complexities and challenges with support costs. Despite this, many consider Nagios XI a cost-effective solution due to its robust features, though some view it as expensive. Free community editions lower initial costs before scaling up.

"As it is not an agentless tool, I think it is expensive."
"Nagios XI is an expensive solution."
"Licensing costs are reasonable."

Popular Use Cases

Nagios XI is primarily utilized for monitoring vast network infrastructures, encompassing servers, switches, and routers. Teams use it to track network devices, operating systems, and server performance, including CPU, memory, and services. Organizations leverage it for both on-premises and cloud environments, monitoring hard drives, bandwidth, and network assets. It supports integration with CRM and ticketing systems, functioning as an effective tool for end-to-end customer support and performance management in diverse settings.

Service and Support

Nagios XI customer service and support receive mostly positive assessments. Many find responses professional and prompt, while others rely on community resources like forums and blogs. Some users note costs are high, and time zones may affect response times. A few report no need for external support due to comprehensive documentation or in-house expertise. Support quality is rated highly by some, although a few mention issues with responsiveness or complexity.

Deployment

Initial setup for Nagios XI is generally straightforward, accompanied by good documentation. However, complexity can arise when integrating plugins or handling network configurations. Setup often requires Linux knowledge, and while simple for experienced users, it can be challenging for beginners. Deployment is time-consuming, particularly when managing multiple devices or custom settings. Some users encounter challenges without a GUI, such as Adagios, while others face performance issues requiring technical support.

Scalability

Nagios XI demonstrates strong scalability for various users and organizations. It performs well for moderate to large infrastructures, with capability to expand disk capacity and integrate distributed monitoring. Users have scaled it successfully across data centers, although challenges arise with configuration and managing large numbers of hosts. Documentation for agent setup can be lacking, leading to complexities. For extensive or cloud-based environments, other options might be preferred. However, scaling in non-cloud environments remains effective.

Stability

Users find Nagios XI very stable with minimal issues. Some report no problems at all, while others note performance challenges with high workloads or specific configurations, often resolved with support. A few mention database-related issues when managing extensive services. Occasionally, stability is affected by network conditions. Despite some performance inconsistencies, most users are pleased with its stability, rating it highly. Its ability to monitor IT infrastructure efficiently is widely appreciated.
