Understanding the structural differences between these two deployment methods helps prevent architectural failures mid-installation.

Once the installer is on the target machine, follow these steps to deploy NPM. 1. Run the Installer

For IT Pros managing secure or air-gapped environments, downloading the SolarWinds Network Performance Monitor (NPM) directly to the target server isn’t always an option.

Deploying NPM offline requires meticulous planning. Because the installer cannot dynamically fetch missing components, you must ensure the target server meets all prerequisites beforehand. 1. Hardware and OS Requirements

After installing SolarWinds NPM using the offline installer, you may need to perform additional configuration tasks, such as:

You must have access to a machine with internet access to download the ISO file from the SolarWinds Customer Portal .

Select the option (this file will be significantly larger than the online version, typically between 3 GB and 5 GB). Download the executable file ( .exe ). Step 2: Transfer the Installer to the Target Server

Enter the hostname or IP address of your SQL Server.

You can download the full ISO file from the Customer Portal on a secure machine, scan it for malware, and move it via physical media.

Paste the Machine ID you copied earlier. The portal will generate a license file (usually with a .lic extension).
