Before beginning, ensure your server meets the recommended hardware and software specifications to ensure optimal performance.
Operating Systems: Supported production versions include Windows Server 2016 to 2025 and Linux distributions like Ubuntu (16.04–24.04), Red Hat (7–9.5), and CentOS Stream 9/10. Hardware Specifications: manageengine netflow analyzer installation guide
Professional Edition: 2.4GHz quad-core processor, 4GB RAM, and 200GB disk space for the database.
Enterprise Edition: 3.2GHz quad-core processor, 8GB RAM, and 1TB SATA hard disk.
Ports: Ensure the following ports are open and not used by other services: Web Server Port: 8060 (HTTP) or 8061 (HTTPS).
NetFlow Listener Port: 9996 (UDP) for receiving exports from routers. Database Port: 13306 (PostgreSQL) or 1433 (MSSQL). 2. Installation on Windows
Download and Launch: Get the latest executable from the official download page and run it with administrator privileges to avoid access issues.
License Agreement: Click Next on the welcome screen and accept the license terms.
Choose Location: Specify the installation directory and click Next.
Configure Ports: Enter your preferred web server and listener ports (default is 8060 and 9996).
Select Database: Choose between the bundled PostgreSQL or an existing MSSQL server. If using MSSQL, ensure the bcp.exe and bcp.rll files are in the bin directory. Complete Installation: Review the summary and click Finish. 3. Installation on Linux
Prepare the File: Download the .bin file and assign execute permissions using:chmod a+x ManageEngine_NetFlowAnalyzer_xxxx.bin.
Execute the Installer: Run the file using sudo:sudo ./ManageEngine_NetFlowAnalyzer_xxxx.bin -i console.
Installation Mode: Follow the on-screen instructions to select the installation directory and configure web server ports.
Database Migration: For Linux, a default installation uses PostgreSQL. To use MSSQL, run the DBConfiguration.sh file from the /bin directory after installation to migrate. 4. Post-Installation & Configuration Once installed, follow these steps to start monitoring: Start the Server:
Windows: Start the "ManageEngine NetFlow Analyzer" service from the Services console.
Linux: Navigate to the /bin directory and execute ./run.sh or use systemctl start NetFlowAnalyzer.service if linked as a service. This guide outlines the draft content for installing
Access the GUI: Open a web browser and go to http://. Use the default credentials admin/admin for the first login.
Antivirus Exclusion: Critically, exclude the NetFlow Analyzer home directory from antivirus scans to prevent database interference.
Configure Devices: Enable NetFlow export on your routers/switches to point to the server’s IP and listener port (9996).
For further details on performance tuning or advanced configurations, you can refer to the ManageEngine Help Documentation.

ManageEngine NetFlow Analyzer is a database-heavy application. The default built-in database (PostgreSQL or MySQL) is suitable for labs, but for production, you need horsepower.
| Number of Flows/sec | vCPU | RAM | Disk Speed (I/O) | Disk Space (per month) | | :--- | :--- | :--- | :--- | :--- | | < 5,000 | 4 Core | 8 GB | 7,200 RPM HDD | 100 GB | | 5k – 15k | 8 Core | 16 GB | 15k SAS HDD | 300 GB | | 15k – 50k | 16 Core | 32 GB | NVMe / SSD | 1 TB | | > 50k | 32 Core+ | 64 GB+ | Enterprise NVMe | 2 TB+ |
Pro Tip: Disk I/O is the number one bottleneck. Do not install this on a budget NAS or a VM with shared slow storage.
