Step-by-Step Guide: Installing ManageEngine NetFlow Analyzer

ManageEngine NetFlow Analyzer is a powerful bandwidth monitoring and network traffic analysis tool that helps IT teams gain deep visibility into their network performance. It supports a wide range of flow formats, including NetFlow, sFlow, jFlow, IPFIX, and AppFlow.

Whether you are deploying it on Windows or Linux, here is a comprehensive guide to getting it up and running. 1. System Requirements & Prerequisites

Before starting, ensure your system meets the hardware requirements (CPU, RAM, and storage) based on the number of interfaces you plan to monitor. Operating Systems:

Windows (7, 8, 10, Server 2012/2016/2019) or Linux (Ubuntu, Debian, CentOS, RHEL). Databases: Supports both PostgreSQL (bundled by default) and Default Port: The web server typically uses port . Ensure this port is open in your firewall. 2. Installation on Windows

Directory Selection: Choose the destination folder for the installation files. Database Configuration: PostgreSQL if you want to use the bundled database. if you have an external SQL server ready. Port Settings: Confirm or change the default web server port (8060).

Complete the wizard. You can start the application as a service by going to Start > Services > ManageEngine NetFlow Analyzer 3. Installation on Linux

Linux installation can be done via a GUI (if X11-enabled) or via the console for headless servers. Using the Console (Silent Mode) Download the file for Linux. Permissions: Assign execute permissions to the file: chmod +x ManageEngine_NetFlowAnalyzer_64bit.bin Run the installer with the console flag: sudo ./ManageEngine_NetFlowAnalyzer_64bit.bin -i console Follow Prompts:

Use the 'Enter' key to scroll through the license and type 'Y' to accept.

Specify the installation directory and the web server port when prompted. 4. Initial Setup & Starting the Service

Once installed, you need to start the application to access the web console. Start the service from the Services menu or run directory in the command prompt. Navigate to the directory in your terminal and execute: After configuration, wait 5–10 minutes

Access the dashboard by opening your browser and navigating to

cd /opt/ManageEngine/NetFlowAnalyzer/bin
sudo sh run.sh

When you see Server started successfully, press Ctrl+C to return to shell? No – In Linux, leaving the terminal kills the process. Instead, open a second terminal or run as a service.

Better method – Run as a background service:

sudo /opt/ManageEngine/NetFlowAnalyzer/bin/NetFlowAnalyzerService start

To check status:

sudo /opt/ManageEngine/NetFlowAnalyzer/bin/NetFlowAnalyzerService status

Once the service starts, access the web console:

https://<your-server-ip>:443
or
http://<your-server-ip>:80

Set Java heap memory based on RAM. For 16 GB system, allocate 8–10 GB for the analyzer. This is critical for avoiding out-of-memory errors.

Before you begin, verify the following:

| Requirement | Details | |--------------|---------| | Operating System | Windows (Server 2016/2019/2022) or Linux (CentOS/RHEL/Ubuntu/Debian) | | CPU | 4+ cores (8+ recommended for >1,000 flows/sec) | | RAM | 8 GB minimum (16–32 GB for production) | | Disk Space | 100 GB minimum (depending on retention) | | Database | Built-in PostgreSQL (or external MSSQL/PostgreSQL) | | Browser | Chrome, Firefox, Edge, or Safari (latest versions) | | Ports | 80 (HTTP), 443 (HTTPS), 9999 (default NetFlow receiver), 2055 (sFlow) |

Note: For production environments with high flow rates, use a dedicated server and SSD storage.
