Download the Linux binary ( ManageEngine_NetFlowAnalyzer_64bit.bin ). Move it to your server and assign execution permissions: chmod +x ManageEngine_NetFlowAnalyzer_64bit.bin Use code with caution. Step 2: Execute the Installer via Console Mode

chmod +x ManageEngine_NetFlowAnalyzer_64bit.bin

For advanced deployments, consider enabling optional modules such as the for automated device backup and compliance, or the Security Module for deeper forensic analysis of traffic patterns.

Installing ManageEngine NetFlow Analyzer involves setting up the server, configuring the database, and ensuring your network devices are exporting data to it. The software is available for both Windows and Linux.

: Open the following default ports in your firewall: Web Server Port : 80 (HTTP) or 443 (HTTPS).

Enter your Name, Email, Company, and Country to sign up for support notifications. Click to review your settings. Step 5: Complete Installation Click Install to start extracting files.

Router# configure terminal Router(config)# ip flow-export destination 9996 Router(config)# ip flow-export version 9 Router(config)# ip flow-cache timeout active 1 Router(config)# ip flow-cache timeout inactive 15 Use code with caution. Apply flow capturing to your active interfaces:

Installation requires local administrator privileges. The software is available for both 32‑bit and 64‑bit architectures, but production installations should always use the 64‑bit version.

Ensure UDP port 9996 is entirely open on the host server OS firewall. Use a packet capture tool like Wireshark to confirm that raw UDP traffic from your router is reaching the server interface.

Have a unique installation issue? Check the community forums or contact ManageEngine support. For high-volume environments (100,000+ flows/sec), consider a distributed setup with a separate database server – but that is a topic for another advanced guide.

Right-click the downloaded ManageEngine_NetFlowAnalyzer_64bit.exe file. Select . Click Next on the Welcome screen. Read and accept the License Agreement. Step 3: Choose Installation Directory and Destination

Ensure the TEMPDIR has sufficient space, especially for Linux installations, to avoid temp folder does not have enough space errors during the process. Using a dedicated machine is also strongly recommended for best performance.

You now have a fully functional ManageEngine NetFlow Analyzer instance. The key post-installation actions are securing the admin account, configuring routers to export flows, tuning memory for performance, and setting up regular backups. For large environments (over 15k flows/sec), consider moving to an external database and using a dedicated 64GB+ RAM server.

For enterprise environments running headless Linux servers, use the command-line interface (CLI) installer. Step 1: Download and Prepare the Binary

sudo systemctl daemon-reload sudo systemctl enable netflow sudo systemctl start netflow
