Nagios Network Analyzer: NetFlow Analysis & Bandwidth Monitoring

NetFlow/sFlow/IPFIX Analysis Wireshark Integration Suricata Rules Nmap Discovery

Analyze traffic flows, monitor bandwidth usage, identify top talkers, and troubleshoot network performance with integrated packet inspection, alerting, and network discovery tools.

NAGIOS IS TRUSTED BY THOUSANDS OF TEAMS WORLDWIDE

From NetFlow To Complete Network Situational Awareness

With open source integrations for industry-standard tools like Wireshark, Suricata, and Nmap, you can take your Nagios NetFlow monitoring to the next level.

Enhanced NetFlow/sFlow/IPFIX Analysis

Unify NetFlow v5, v7, v9, sFlow, J-Flow, and IPFIX data streams into a comprehensive monitoring and analysis platform. Get granular visibility down to individual flows with configurable retention periods and 5-minute updates for near real-time traffic monitoring and proactive performance optimization.

Rapid Threat Analysis

Capture and inspect packets in real time with Wireshark or import PCAPs from other sources for analysis. Achieve rapid intrusion detection and alerting with live Suricata scans, or scan imported and Wireshark-generated PCAPs for threats. Execute live or scheduled network discovery scans with Nmap to identify open ports and security risks.

Unified Security and Discovery Platform

Achieve complete network situational awareness through integrated Wireshark, Nmap, and Suricata capabilities. Schedule automatic network discovery scans and compare results, receive rule-based alerts when security events occur, and gain insight and context through packet analysis and integration cross-reference to accelerate threat response.

Nagios Network Analyzer Features

Monitor Network Traffic, Detect Issues, and Resolve Problems Faster

Comprehensive Dashboards

Powerful, customizable dashboards enable each user to create crisp visualizations showing traffic and top talkers on the sources that are most important to them, along with high-level scheduled Nmap scan data.

Advanced Traffic Analysis

Analyze flow data, monitor bandwidth usage, inspect packets, and drill into traffic patterns from a single interface. See which hosts, applications, and conversations are consuming network resources so your team can resolve congestion and performance issues faster.

Automated Alert System

Receive alerts when query-based flow events, Suricata Signature IDs, or open/closed ports in Nmap scans match defined criteria. Email notifications directly, forward results to Nagios, or send an SNMP trap when problems are detected.

Monitoring Server Integration

Seamlessly integrate with Nagios XI for centralized visibility of alerts from both solutions. Create checks within Network Analyzer to send results upstream to XI, or run the Network Analyzer Wizard in XI to actively monitor source or source group traffic.

Industry-Standard Tool Integrations

Monitor Traffic, Detect Threats, & Map Infrastructure From A Single Pane of Glass

Nmap Integration (Tshark) – Network Scanner and Network Mapper

Wireshark is a network protocol analyzer used to capture and inspect network traffic in real time. It supports hundreds of protocols and provides deep insight into network communications for troubleshooting, analysis, and security auditing.

Real-time network traffic analysis
Support for a wide range of protocols
Detailed packet inspection capabilities
Open-source and widely used in the industry

In-Depth Packet Inspection

Capture and inspect packets for detailed troubleshooting and forensic analysis.

Triggered Captures from Alerts

Initiate targeted packet captures directly from Suricata alerts for deeper investigation.

Investigation Support

Save packet captures to support investigations and document network activity.

Suricata Integration - Rule-Based Alerting and Detection

Suricata brings real-time intrusion detection and prevention to your network analysis. By inspecting traffic at the packet level, Suricata can detect exploits, malware, and policy violations as they happen. With detailed alerts and logs, it helps strengthen your defenses and supports faster incident response.

Detect malware, exploits, and policy violations in real time
Cross-reference Suricata packet data with Nmap and Wireshark for deeper insights
Send real-time Suricata alerts via email for immediate awareness
Support incident response with detailed logs and metadata
Improve threat visibility alongside flow and packet data

Real-Time Threat Detection

Identify malware, exploits, and policy violations the moment they occur.

Alerting & Notifications

Send alerts to designated recipients for faster response and improved incident handling.

Detailed Investigation Support

Support investigations with detailed logs and metadata.

Nmap Integration - Network Mapping and Scanning

Nmap provides powerful network scanning capabilities that help you maintain visibility into the devices and services running in your environment. By scheduling scans and automatically comparing results with ndiff, you can quickly detect newly added or removed hosts, track changes to your network, and identify potential security risks.

Discover hosts and services across your network with fast, accurate scans
Schedule recurring scans to maintain up-to-date visibility
Use ndiff to detect newly added or removed devices after each scan
Identify open ports and exposed services that may pose security risks
View historical scan results to monitor changes in your network environment

Comprehensive Network Discovery

Identify hosts and services across your network with fast, accurate scanning.

Scheduled Visibility

Run recurring scans to maintain continuous awareness of network changes.

Change Detection with ndiff

Detect new or removed devices after each scan comparison.
