Not bad overall, but also it is only good for smaller networks, can get chaotic when you add a ton of stuff to it, Plus the graphs are not alwways easy to read, you have to understand more than your average to get the graphs, and the different aspects of it. Not just networking. **What problems is Nagios Network Analyzer solving and how is that benefiting you?** It is great at alerting us when something is wrong. Either a device or a service we run.

One for the monitored endpoints, one for each of the services of such endpoints, and group policies for different alarm/escalation settings profiles make it an excellent and extensive framework that is highly modifiable and adaptable for systems like monitoring routers, switches, firewalls, servers, and site locations. **What do you dislike about Nagios Network Analyzer?** We cannot see full visibility and are unable to recognize all traffic flows due to heterogeneous network topology, we are not able to deploy it for the production environment, it does not optimally support inter-VLAN routing scenarios but it remains undoubtedly the top choice for having a complete and comprehensive view, as well as the most in-depth insight on WAN links at the edge level or circuit terminating/aggregating router. **Recommendations to others considering Nagios Network Analyzer:** I recommend executing a deployment on a physical machine and not a virtual one (guest VM) because scaling your network might require additional physical connections at level 1 and data link of the TCP IP stack. **What problems is Nagios Network Analyzer solving and how is that benefiting you?** We use Nagios Network Analyzer because it allows us to inform on-call personnel about service interruptions for multiple teams, via email and SMS or even Telegram bot and Telegram API.

A Jack of all Trades **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Internet | Enterprise (> 1000 emp.) **Reviewed Date:** September 29, 2016 **What do you like best about Nagios Network Analyzer?** Malleability is Nagios' true strongpoint. I have seen it used in 3 fairly different environments. I've used 3 different frontends, currently using 2, to interact with the nagios backbone. Each having their own strengths and weaknesses respectively. When it comes to interacting directly with it via the CLI, while not the nicest to look at or work with, it does exactly what you tell it to. **What do you dislike about Nagios Network Analyzer?** Directly editing configurations can sometimes be a bit of a process due to having to dig through the files in the terminal. You get out what you put in, and for most people the quality of their nagios experience will have to do with what front-end they end up putting in. **Recommendations to others considering Nagios Network Analyzer:** I have only ever used nagios to monitor systems, would recommend for large scale operations. It is able to handle all of our needs and is highly customizable when it comes to its alerting. I would recommend looking into the various front-ends that are available for it, as that will determine a large chunk of your experience. **What problems is Nagios Network Analyzer solving and how is that benefiting you?** In all the scenarios where I have used nagios, it has been the monitoring of a vast amount of servers/systems and being able to report issues quickly. Without nagios, the online business unit operations teams would be operating "blind". ### 30. Works well, if a little clunky to set up. **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Government Administration | Mid-Market (51-1000 emp.) **Reviewed Date:** June 07, 2016 **What do you like best about Nagios Network Analyzer?** It monitors everything we threw at it. It can even tie into pagers (yes, old style beepers) to deliver notifications. Down time and maintenance notifications are easy to use. The add ons really make this product shine -- with the help of free libraries of addons and plugins online there is very little that can't be monitored by this software. Plus, the price is right! **What do you dislike about Nagios Network Analyzer?** It can be a little clunky to configure -- manually editing text files in a CLI isn't exactly my idea of a great time. There are GUI plugins available, but I have yet to find one that works as well as simply editing the config files. **What problems is Nagios Network Analyzer solving and how is that benefiting you?** This is our backup monitoring solution -- a "who's monitoring the monitor" thing. It works very well. ## Nagios Network Analyzer Discussions - [What is Nagios Network Analyzer used for?](https://www.g2.com/discussions/what-is-nagios-network-analyzer-used-for) - [Does Nagios use SNMP?](https://www.g2.com/discussions/does-nagios-use-snmp) - [How does Nagios monitoring tool work?](https://www.g2.com/discussions/how-does-nagios-monitoring-tool-work) - [What are the features of Nagios?](https://www.g2.com/discussions/nagios-network-analyzer-what-are-the-features-of-nagios) - [What can you monitor with Nagios?](https://www.g2.com/discussions/what-can-you-monitor-with-nagios) - [View Nagios Network Analyzer pricing details and edition comparison](https://www.g2.com/products/nagios-network-analyzer/reviews?section=pricing&secure%5Bexpires_at%5D=2026-06-19+19%3A20%3A42+-0500&secure%5Bsession_id%5D=66195374-7999-4d01-9e74-99625290c805&secure%5Btoken%5D=7bad73b611e8e449cc468eaf97dd0b7211f8e804ecb48bdb492d88506d7b933d&format=llm_user) ## Nagios Network Analyzer Features **Functionality** - Performance Monitoring - Alerting - Multi-Network Capability **Monitoring - Network Monitoring** - 360-Degree Network Visibility - Automated Network Discovery - Real-Time Monitoring **Management** - Data Visualization **Analytics - Network Monitoring** - Predictive Performance Analytics - Packet & Flow Analysis **Security - Network Monitoring** - Encrypted Data Transmission - Zero Trust and Identity Management - Integrated Network Security **Network Performance - Network Monitoring** - Dynamic Network Optimization - Automated Tasks Routing **AI Automation - Network Monitoring** - Machine Learning-Based Anomaly Detection - Self-Healing Networks - Predictive Network Maintenance **Agentic AI - Network Monitoring** - Autonomous Task Execution - Multi-step Planning - Cross-system Integration - Adaptive Learning - Natural Language Interaction - Proactive Assistance - Decision Making ## Top Nagios Network Analyzer Alternatives - [Paessler PRTG](https://www.g2.com/products/paessler-prtg/reviews) - 4.7/5.0 (203 reviews) - [Zabbix](https://www.g2.com/products/zabbix/reviews) - 4.4/5.0 (204 reviews) - [LogicMonitor](https://www.g2.com/products/logicmonitor/reviews) - 4.5/5.0 (586 reviews)
