Benefits of using Nagios Network Analyzer

Extensive Network Analysis

This network security software provides an in-depth look at all network traffic sources and potential security threats allowing system admins to quickly gather high-level information regarding the health of the network as well as highly granular data for complete and thorough network analysis.

Network Clarity

Network Analyzer provides a central view of your network traffic and bandwidth data as well as potential network compromises. The powerful home dashboard provides an at-a-glance view of critical Netflow or flows data sources, server system metrics, and abnormal network behavior for quick assessment of network health. Users can easily drill down to see specific information on individual IPs, source port, destination port, or any combination thereof.

Adaptability

Create a Network Analyzer environment that reflects your network’s identity. Source groups allow Admins to organize similar sources as well as apply views and queries to multiple sources simultaneously, and to your exact specifications. Additional add-on capabilities allow Network Analyzer users to push SNMP notifications to monitor and SNMP trap management systems. Network Analyzer adapts to your existing environment for a pain-free implementation process that takes only minutes to get up and running.

Intuitive Design

With a powerful and intuitive web interface, Network Analyzer is easy to use, while providing optimal performance and speed. Network Analyzer seamlessly integrates with our network monitoring solution, Nagios XI, allowing for the consolidation of alerts and notifications as well as maintaining a safe and secure network. Easily set up alerts and add sources with Network Analyzer’s intuitive wizards with just a few clicks.

In-Depth Insight

Network Analyzer’s advanced alerting and reporting capabilities provide IT, staff, with a superior awareness of their network. Highly granular, down-to-the-packet data can be accessed and archived for further tracking and analysis. When critical thresholds are exceeded, abnormal network activity occurs, or bandwidth restrictions are met, Network Analyzer can trigger alerts allowing Admins to start resolving issues immediately.

Bandwidth Utilization Calculator

A fully customizable bandwidth utilization calculator is included allowing reports to be created to summarize bandwidth utilization per source, IP, or any combination the user desires.

Frequently Asked Questions

Why do you want Nagios Network Analyzer?

Have you ever asked yourself, “Where is all my bandwidth going?” If you want to see more metrics about your network than just how many bytes are getting shuffled around, you want data analyisis of system! Being able to determine exactly which IP addresses are contacting your server and hogging your bandwidth is extremely valuable. Network Analyzer keeps a record of all internet traffic information and allows you to see exactly who connected to your server on a given port and actually get answers. Sample use cases include capacity planning, intellectual property security and corporate data leak protection, security breach, and unauthorized access detection, virus and malware detection, setting QoS baselines, and more!

Can Network Analyzer be deployed to physical servers?

Yes! The manual installation of physical servers is recommended. The server must be RHEL or CentOS. It also distributes Nagios Network Analyzer as a virtual machine to allow you to get it up and running quickly.

Will Network Analyzer show me the contents of internet traffic? (ex: pictures or passwords)

No. Network Analyzer does not show you that information. It will show you how much information went between two computers, average size in bytes per packet, and lots of other information in that realm, but it will not tell you the content of the traffic. Network flow data keeps track of who was talking to who on what port and protocol and the amount of data sent, but not the content of the conversation.

Does Network Analyzer require the opening of firewall ports?

Yes. Network Analyzer requires that ports be opened up to allow network flow data to be delivered. The ports that need to be opened are determined by the administrator when setting up Network Analyzer to receive the flow data. They will use one port per source they are receiving flow data from.

How long does Network Analyzer store network flow data for?

This is totally up to the discretion of the user. The default is 24 hours, however, when the user creates a new source they are prompted to specify how long they desire to store their data. This can be for as long as the user desires, but keep in mind that network flow data technologies take up a large amount of disk space. Not only that, but the extra parsing through the files puts unnecessary strain on the CPU if they don’t care about information, but are still keeping it.

Can you be alerted when things go wrong?

Yes! Network Analyzer has out-of-the-box integration with Nagios XI and can send results to Nagios Core. Network Analyzer can also send email alerts and SNMP traps. Network Analyzer is a whole lot more than just pretty graphs.

Can you see who is browsing specific websites?

Yes! Network Analyzer can perform DNS resolution of hostnames such as facebook.com or youtube.com and will allow you to abstract your queries in that fashion.
