SentryOne Portal Configuration

Note:  SentryOne Portal requires SentryOne software version 20.0 or above.

What is SentryOne Portal?

SentryOne Portal is a browser-based option for accessing your SentryOne environment data that uses your existing SentryOne database. It replaces the previous mobile applications and Cloud Sync options.

Additional Information: See the SentryOne Portal article.


Before installing SentryOne Portal on-premises, ensure your credentials and machine(s) meet the System Requirements as well as the security and additional requirements listed below:


  • The SentryOne Portal requires the use of SQL Server Authentication for the SentryOne Portal service account to connect to the SentryOne database.
    • The SQL Server account must have read, write, and execute access to the SentryOne database.
  • Accounts logging into the SentryOne Portal through a browser must have access to the Windows Server hosting SentryOne Portal.

Additional Requirements

  • Chrome and Edge are the recommended browsers for using SentryOne Portal.
  • Configured SentryOne database (version 20.0 or greater) that's accessible by the web server
  • Latest SentryOne.Monitor.WebClient.Web artifact or the latest version of the Enterprise Platform Installer
  • The preferred IP address and port that SentryOne Portal should use to listen for HTTP traffic


  • The SentryOne Portal service can only listen to HTTP traffic. If you want to use HTTPS, you need to setup a reverse proxy through IIS or other reverse proxy solution.
  • If you plan to change the binding address or port, ensure that there isn't already something listening to that address and port on the machine.
  • The default IP address is SentryOne Portal listens to all IP addresses on the machine that are not listening to the selected port.
  • The default port is 9991.
  • It's recommended to set the IP address to if you're planning to route requests through IIS or other reverse proxy on the same machine as the service. This will prevent external requests from directly reaching the service.

Installing SentryOne Portal

SentryOne Portal may be installed via the classic SentryOne Setup Wizard or through the EPI commands, as long as the method you choose matches your existing SentryOne installation.

Where can SentryOne Portal be Installed?

SentryOne Portal can be installed on-premises with a self-hosted configuration as a service.

Note:  SentryOne Portal cannot run as an Internet Information Services (IIS) site. IIS may only be used as a reverse proxy to the SentryOne Portal service for SSL and request filtering. See the IIS Reverse Proxy Configuration section below for details.

Install SentryOne Portal using Setup Wizard

Follow the instructions in the SentryOne Installation article.

Install SentryOne Portal using EPI

Follow the Installation, Upgrade, and Uninstall instructions in the SentryOne Enhanced Platform Installer article.

IIS Reverse Proxy Configuration (Optional)

Additional Information: The following steps cover the process required to set up IIS as a reverse proxy to the SentryOne Portal service for SSL and request filtering. For information about IIS administration, see

IIS Reverse Proxy Prerequisites

The following modules must be installed before configuring your reverse proxy:

Note:  These required modules are not installed by default.

IIS Reverse Proxy Instructions

Configure a reverse proxy in IIS to host SentryOne Portal by completing the following steps:

1. Create a website with your desired outward bindings. If you want to use HTTPS, this is where you will register your SSL certificate. Point the site to the default IIS directory.

Note:  The default IIS directory is often C:\inetpub\wwwroot. The Application Pool settings wont have an effect on the behavior of this site because it will not be executing code. You can set the .NET CLR version to No Managed Code, but this is not required. 

2. Open the Home window for the new site, and select the URL Rewrite feature.

SentryOne Portal Configuration IIS select URL Rewrite

3. Select the Add Rule action from the right window pane, and then select Reverse Proxy rule from the Inbound and Outbound Rules category.

SentryOne Portal Configuration Add Rule(s) select Reverse Proxy

4. Enter the IP address and port of the service in the Inbound Rules server name input. Ensure that Enable SSL Offloading is selected. Select OK to save the rule. SentryOne Portal Configuration Add Reverse Proxy Rules enter Inbound Rule

Note:  Localhost:9991 is the default IP address.

Success: IIS now routes all requests to the website to the SentryOne Portal service.

SentryOne Portal Configuration Utility

Important:  The SentryOne Portal Configuration Utility cannot be used with the EPI version of SentryOne. To make changes using EPI, you must uninstall SentryOne Portal (via uninstallmp), then reinstall using the installmp command with the new settings.

Changes to your SentryOne Portal configuration must be made through the Portal Configuration Utility (PCU).

Accessing the PCU

  1. Navigate to the MonitorPortal directory in your SentryOne installation. The default path is C:\Program Files\SentryOne\<Version>\MonitorPortal. In this example, it is  C:\Program Files\SentryOne\2020.0\MonitorPortal.
  2. Locate the SentryOne.Monitor.WebClient.ConfigurationUtility file and use the Run as administrator option to open it.

Using the PCU

The PCU allows you to change database, network, security, and web server binding-related properties for SentryOne Portal. Select the Verify & Save button to apply any changes.

The PCU also provides an option to stop/start the SentryOne Portal service (SentryOneMonitorPortal in Windows Services).

DEPRECATED: Installing SentryOne Portal On Premises Manually


  • SentryOne Portal must be installed outside of the user's directory.
  • These steps are included only for users who do not have the current release of SentryOne with the installation built in. It was added to the installer in version 2020.8. If you have version 2020.8 or later, you must use the EPI or Setup Wizard instructions to install it.

After you have ensured that your machine meets the prerequisite requirements, you can begin installing SentryOne Portal. Install SentryOne Portal on your machine manually by completing the following steps:

1. Unzip the SentryOne.Monitor.WebClient.Web artifact at the desired location on the machine hosting SentryOne Portal.

3. Run the service install script OnPremServiceInstall.ps1 as administrator. Enter the IP address and port that you want to bind the service to in the appropriate prompt.

SentryOne Portal Configuration Windows Powershell Run as administrator

SentryOne Portal Configuration Execute OnPremServiceInstall.ps1
Execute the PowerShell Command, enter the IP, and enter the Port

Note:  To use integrated authentication for the database connection, you need to change the account that the SentryOne portal service is running under in the Windows Services Control panel after installation. The default account is LocalSystem.

Note:  You can re-run the service install script OnPremServiceInstall.ps1 at any time to change the IP address or port and update the service. The SentryOne Portal service will be turned off during the script's execution.
