Nagios XI and Kentik are both competitors in the network monitoring and analysis category. Nagios XI holds an advantage in cost-effectiveness due to its open-source flexibility and comprehensive service monitoring. In contrast, Kentik shines in traffic analysis and flow detection thanks to its robust NetFlow visualization.
Features: Nagios XI is characterized by its configurable and scalable monitoring capabilities enhanced through customizable plugins. It supports a diverse range of network services and allows users to write their own scripts due to its open-source architecture. Kentik provides robust traffic insights, aiding in network planning, security, and real-time troubleshooting. Its SaaS model reduces management complexity, eliminating the need for additional server oversight. Both are well-suited to different application types in network monitoring.
Room for Improvement: Nagios XI faces scaling challenges and requires scripting knowledge for advanced configurations. It lacks a failover feature and needs better clustering solutions. Kentik's pricing model and API complexity are pain points, with recommendations for enhanced user-friendliness and actionable insights in flow analysis. Integrating better with performance tools is another improvement area for Kentik.
Ease of Deployment and Customer Service: Nagios XI offers a variety of deployment options, including on-premises and hybrid cloud environments, with support from an open-source community though initial setup may be intricate. Customer support experiences are mixed, with responsiveness being a concern. Kentik supports private and on-premises cloud deployments, and its customer support is responsive, albeit with time zone challenges.
Pricing and ROI: Nagios XI, especially in its open-source iteration, is cost-effective and offers immediate ROI due to low upfront costs. Licensing is competitive, although some view it as expensive compared to its open-source version. Kentik, priced by devices and data flow, is considered expensive but scales effectively with large volumes. Discounts are offered to educational institutions, and both solutions provide ROI through time savings.
If we had, for example, a contracted capacity from Vivo of 50 GB and we were using 40, with Kentik we reduced this usage from 40 to 20.
In production environments, especially for service providers on IP networks and data centers, Kentik helps in reducing the time to identify and resolve issues.
I believe the return on investment has been mainly time savings in performing troubleshooting.
I have mostly used forums for any support needed because the setup is straightforward and the documentation is quite good.
They have monthly calls and discuss the product roadmap with us to determine what is needed.
Kentik's integration with Kubernetes makes scaling easier.
Kentik's scalability is effective; the platform can handle these large volumes.
Kentik's scalability depends on how it is contracted.
If the user interface isn’t presenting data well, it becomes difficult to manage when scaling.
In production, however, dimensioning of the underlying platforms is something to be mindful of.
Based on stability, I would give Kentik a nine.
I can say it is so great for us because if we configure it with Flowspec, the orchestration that we use, which is Kentik, makes the decision and automatically forwards the traffic to another position that we have in our network, or outgoing that we use.
It is very stable.
More work is required to integrate AI for troubleshooting, simplifying root cause analysis, and providing suggested solutions for network issues.
It needed to be a bit easier for new users and have slightly more customized reports.
Currently, the way I'm configuring it uses reactive alerts, which means alerts are triggered when an issue occurs. I would prefer more proactive alerts in the future.
Many tools have poor user interfaces, making them hard to manage and navigate.
The GUI could be improved. It's a bit too basic.
The pricing is good and aligns with the market target.
Kentik’s pricing is competitive in the marketplace.
Later, the prices are very high to maintain all the functionality blocks.
We are using the free, open-source version.
The pricing for the Nagios XI product is good and better than other solutions.
The best features that Kentik offers are the ability to identify traffic end-to-end and to know which transit is used, if it goes through any other transit, to see the entire flow, from the subscriber to the content provider and vice versa.
This allows for better understanding of whether there is a critical ongoing case related to incoming traffic, such as a DDoS event, which is crucial for a service provider dealing with numerous customers.
Kentik has positively impacted our organization because when something happens, we use Kentik to analyze the problem and it brings us a faster solution to the problem, and the troubleshooting is clearer.
Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.
The alerting system is very effective.
