Agent installation for Windows

On this page

Introduction

The Service Desk Discovery Agent runs as a service. After the agent is installed, it automatically updates any and all core libraries it runs on, as well as future enhancements (code).

SolarWinds doesn't push anything to the agent/scanner from our servers. The agent is designed to check for updates from the server.

When updates are available they get installed. On average, the agent is updated quarterly.

In addition, the SolarWinds Discovery Agent Watchdog Service keeps watch on the Solarwinds Discovery Agent Service, and restarts it if it stops for any reason.

Use the information in the following sections to install the Discovery Agent on a single Windows computer. After you complete the deployment and setup procedures on one computer, you can perform a mass deployment to install the agent on host devices throughout your organization.

Navigation

Setup > Discovery & Assets > Installation.

Prerequisites

Ensure that the following prerequisite requirements are met before installing.

Firewall requirements

The following domains and ports must be allowed.

Purpose	Destination IP	TCP/UDP	Destination Port	Protocol
Report asset data to the Service Desk platform	agt.samanage.com + agteu.samanage.com (EU accounts only) + agtau.samanage.com (AU accounts only)	TCP	443	HTTPS
Obtain the external IP address for monitored devices	opendns.com	UDP	53	DNS

Purpose

Protocol

Report asset data to the Service Desk platform

+ agteu.samanage.com
(EU accounts only)

+ agtau.samanage.com
(AU accounts only)

HTTPS

Obtain the external IP address for monitored devices

DNS

Although the required firewall settings are only for outbound traffic (Destination IP and Port), when a session is initiated from inside the firewall, it allows incoming traffic because it knows it is a response to a legitimate request.

Network Service account

The Discovery Agent requires an NT Authority|Network Service account. The NT AUTHORITY\NETWORK SERVICE account is a built-in Windows account that has limited privileges and is commonly used to run services that need to access network resources. See Network Service Account (Microsoft Learn).

Installation

You need administrator permissions to run the installer. If you are not logged in as an administrator, you will be prompted to Run as administrator. When you run an admin-enabled command window, a command prompt is not required.

The first step in the installation process is to download the Discovery Agent (MSI or EXE). After downloading, you have the following options for installing it on a single computer:

Run the MSI file.
Run the Discovery Agent EXE Setup wizard
Perform silent installation using a command line.

You can deploy the discovery agent on Windows and macOS devices.

Download the Agent installation file for Windows

Navigate to Setup > Discovery & Assets > Installation.
To the right of Discovery Agent Windows, click Download MSI/EXE file.
From the dropdown, select the file type you want to download (MSI or EXE) and save it to your local computer.
Run the file you downloaded:
- If you downloaded the MSI file, you can open the file to install on your local computer.
- If you downloaded the EXE file, you need to run the Discovery Agent Setup wizard.

Run the MSI file

Open the MSI file and follow instructions.

You must use a local administrator account to use the domain logon script procedure.

You can also perform a silent installation of the MSI file. See Silent MSI Install.

Run the Discovery Agent EXE Setup wizard

Review the installation prerequisites and employ all required corporate security measures in your deployment.
Launch the Discovery Agent wizard.
At the Welcome message, click Next to begin.
If you agree with the license agreement, select I accept the agreement, and then click Next.
In the Ready to Install dialog, click Next.
When prompted, click Finish to complete the installation.

When the installation is complete, the Discovery Agent runs an inventory scan for the first time. This may take several minutes to complete.

The agent then begins reporting on the pre-configured parameters (for example, hardware and software). It may take a few moments for the information to display in your Service Desk instance.

Perform silent installation using a command line

Msiexec can be used to install, modify, and perform operations on Windows Installer from the command line. For more information, see msiexec.

If you want to install the Discovery Agent using a Windows command line, perform the following steps:

Open Terminal.
Navigate to the Download folder.
Execute the installer with the mode unattended and proxy command line arguments.
```
                    "<folder>\Solarwinds_Discovery_Agent_<version>_installer.exe" --mode unattended
--enable_proxy 1 --proxy_address [address] --proxy_port [port] --proxy_username [username] --proxy_password [password]
                
```
Replace [address], [port], [username], [password] with the appropriate information based on the related proxy.

Be aware that Service Desk cannot pick proxy settings automatically. Proxy settings are saved to the configuration file and are used for agent communication.

Running the installer as an administrator is not required. However, you will be prompted to run the installation as an administrator. When you run an admin-enabled command window, a command prompt is not required.

Install MSI using silent command

You can also choose to perform a silent installation of the MSI file.

            msiexec /i c:\softwares\Solarwinds_Discovery_Agent_{{version}}_installer.msi /qn

Instructions for golden image vendor

Install the discovery agent on a machine that will be used as a base image for deployment.
Delete the history.yml file from the agent as part of machine creation process before sealing the image. The history.yml file is located at:
- Program Files\Solarwinds Discovery Agent\data\history.yml
  or
- Program Files (x86)\Solarwinds Discovery Agent\data\history.yml.

The history.yml file contains references to the machine instance that was used to create the master image. Deleting the history.yml file aids in preventing potential reporting conflicts, such as entries not having the correct serial number when reported back by the agent.

Mass deploy

After the single deployment is complete, you can perform a mass deployment. See Agent installation for mass deployment.

Uninstall the Discovery Agent

To uninstall the Discovery Agent, go to Control Panel > Programs and Features > Uninstall a program. Select the agent and complete the uninstall procedure.

Uninstall using command line

            "C:\Program Files (x86)\Solarwinds Discovery Agent\uninstall.exe"

For silent uninstall use

            "C:\Program Files (x86)\Solarwinds Discovery Agent\uninstall.exe" --mode unattended

            @echo off
REM === Agent already deployed on the computer?
if exist "C:\Program Files\Solarwinds Discovery Agent\agent\src\mini_kernel\service.*" goto END
if exist "C:\Program Files (x86)\Solarwinds Discovery Agent\agent\src\mini_kernel\service.*" goto END
REM === Uninstalling agent in silent mode"C:\Program Files (x86)\Solarwinds Discovery Agent\uninstall.exe" --mode unattended
REM === Script done
:END

Force an inventory refresh for the Discovery Agent

After you enable the Discovery Agent, the agent inventory automatically updates every 24 hours. The agent runs as a Windows service and triggers a refresh based on that schedule.

To optimize for outbound bandwidth utilization, the agents randomize the next inventory refresh within a 24-hour time frame. This process prevents all agents from reporting at the same time.

Optionally, you can force the agent on a targeted machine to manually push an update. To push the update, open a Command Prompt window and run the following commands or copy the code into the prompt. If the prompt does not return an error message, the procedure completed successfully.

Potential error/warning message

Message: When performing a force update command for Windows computers, you might receive a warning message:

Starting force data collection

Ignoring racc-1.6.0 because its extensions are not built. Try: gem pristine racc --version 1.6.0

Done!

Solution: Ignore the message. Wait a few minutes so the Discovery agent messages are processed and reflected in Service Desk. Be aware that it could take 6-7 hours for the data to be imported into Service Desk.
