ThousandEyes and Nagios Core are prominent players in network and application monitoring. ThousandEyes appears to have an upper hand due to its commercial edge in customer support and cloud versatility.
Features: ThousandEyes provides deep network visibility and application monitoring, comprehensive monitoring of cloud providers and ISPs, and effective scalability integrated with Cisco. Nagios Core offers open-source flexibility, customization for varied endpoints, and cost-effectiveness with custom plugins.
Room for Improvement: ThousandEyes requires better integration, advanced application monitoring, and improved dashboards. Nagios Core struggles with user-friendliness, modern aesthetics, and ease-of-use, suggesting more intuitive interfaces.
Ease of Deployment and Customer Service: ThousandEyes supports on-premises, hybrid, and cloud deployments with responsive technical support. Nagios Core focuses on on-premises deployments and lacks dedicated support due to its open-source nature.
Pricing and ROI: ThousandEyes positions itself in the mid-to-high price range, promising ROI with network performance enhancements. Nagios Core offers cost-effectiveness through zero licensing fees and emphasizes savings in monitoring costs.
There has been a great ROI from using ThousandEyes, with significant time saved in troubleshooting as I can quickly pinpoint issues rather than spending time isolating them, alongside enhancing customer feedback and experience.
I have seen a return on investment by reducing troubleshooting time and having lesser user mapping error issues, in addition to engineering time saved through better observability and reduced organizational MTTR.
We contacted the support team, and they resolved it within a couple of hours.
The customer support for ThousandEyes is very proactive and supportive.
The solution is scalable.
ThousandEyes's scalability is excellent; it is very scalable and grows with my organization's needs.
Scalability with ThousandEyes is straightforward as you don't really need to scale; it's designed to monitor multiple applications, accommodating 50 or 100 applications simultaneously.
I tried many other solutions at work, however, in terms of Nagios, I haven't seen any disruption or downtime.
From my experience, ThousandEyes has been stable up to 95%; I have not seen any stability issues.
ThousandEyes is not very stable; sometimes you have to reboot the servers to get actual results.
Incidents should be alerted on and traced early, before they escalate to full outages.
ThousandEyes can also, in terms of providing more extensibility with other observability tools, offer more out-of-the-box integrations.
Introduction of a free version for end-users and enhancements to the user interface for easier navigation.
My experience with pricing, setup cost, and licensing has been that everything was cost-effective.
My experience with pricing, setup cost, and licensing is that it comes in cheaper than alternatives.
You can monitor anything.
ThousandEyes has become critical for swift network troubleshooting as well, so anytime that there's potential issues with applications or we want to be proactive in resolving potential issues before they arise, ThousandEyes is really the platform that we're leveraging for WAN monitoring, Wi-Fi, latency, packet loss, etc.
With ThousandEyes being able to detect and monitor this, it's fantastic for me. It reduces the workload and also reduces errors in trying to figure out where there is internet downtime, low visibility, or other incidents.
I measure the 70% improvement in customer experience through customer tickets and feedback after resolving issues, where previously, users faced problems and limited time on the platform, and after using ThousandEyes, the user time reached up to five to six hours a day, even for teams possibly totaling 30 hours a day.

This is IT infrastructure monitoring's industry-standard, open-source core. Free without professional support services.
ThousandEyes is a Network Intelligence platform that delivers visibility into every network an organization relies on, whether public or private. ThousandEyes enables users to optimize application delivery, end-user experience and ongoing infrastructure investments.
With cloud, enterprises can innovate much faster, but the growing number of cloud and SaaS applications means that more apps are being delivered over the Internet. This increases dependence on the Internet, a public “best effort” network, and other third-party infrastructures, substantially reducing the ability of IT teams to predict, visualize and control operational behavior. This results in a chaotic and unmanageable IT environment, making issue resolution a time-consuming ordeal, potentially impacting reputation and revenue. ThousandEyes has innovated an approach based on an unmatched distribution of smart agents across the Internet and enterprise, providing visibility all the way to the end user. ThousandEyes gathers and analyzes massive volumes of Network Intelligence data from all of these vantage points, enabling organizations to solve even their most obscure performance problems in minutes. By using ThousandEyes in the planning and testing phases of cloud adoption, customers can also strategically identify and fix underlying problems before production deployment of business-critical applications.
The ThousandEyes solution is ubiquitous across industry sectors, and since launching in mid-2013, customers have come from a diverse set of industry sectors, which include Silicon Valley technology companies, financial services, healthcare, pharmaceuticals, retail, manufacturing and education.
