SolarWinds Orion scalability engines, including Additional Polling Engines and Additional Web Servers, extend the monitoring capacity of your SolarWinds installation.

Requirements and recommendations will vary from product to product. Go to your product's documentation page in the SolarWinds Success Center for more information.

See Requirements in the Scalability Engine Guidelines.

Pre-flight checklist

Before you install an Additional Polling Engine in your environment, be sure you complete the following actions:

Be sure your product uses Orion Platform 2016.2 and later.

To find out the Orion Platform version, log in to the Orion Web Console and see the Orion Platform version in the footer. If the version is 2016.1 and earlier, see Orion Bundle for additional servers.

File:Success_Center/Reusable_content_-_InfoDev/NPM/Test_2/0190-Plan_your_production_deployment/checkbox.gif Install or upgrade the Main Polling Engine.
File:Success_Center/Reusable_content_-_InfoDev/NPM/Test_2/0190-Plan_your_production_deployment/checkbox.gif Ensure product versions match between the Primary Polling Engine, all Additional Polling Engines, and Additional Web Servers. This includes the version of .NET. Find a version number listed in the footer of the Web Console. If your product versions do not match, you must upgrade before you can install Additional Polling Engines.
File:Success_Center/Reusable_content_-_InfoDev/NPM/Test_2/0190-Plan_your_production_deployment/checkbox.gif Verify port requirements for your SolarWinds product.
File:Success_Center/Reusable_content_-_InfoDev/NPM/Test_2/0190-Plan_your_production_deployment/checkbox.gif Acquire a user name and password with administrative privileges to the Orion Web Console on your Main Polling Engine.
File:Success_Center/Reusable_content_-_InfoDev/NPM/Test_2/0190-Plan_your_production_deployment/checkbox.gif Be sure the Additional Polling Engine uses the same SQL database as the Main Polling Engine.
File:Success_Center/Reusable_content_-_InfoDev/NPM/Test_2/0190-Plan_your_production_deployment/checkbox.gif If you configured an alert with a Send Email action to trigger on a node monitored by an Additional Polling Engine, confirm that the Additional Polling Engine can access your SMTP server.

Add the IP address of your Additional Polling Engine to Windows Servers on the Security tab.

Make sure that the following options are set:

  • Ensure that a case-sensitive community name has been specified.
  • Ensure that Accept SNMP packets from any host is selected OR ensure that the ipMonitor system is listed within the Accept SNMP packets from these hosts list.
  • Ensure that your network devices allow SNMP access from the new polling engine. On Cisco devices, you can for example modify the Access Control List.

Install an Additional Polling Engine

The Additional Polling Engine or Additional Web Server is installed, together with all hotfixes for products released later than September 2016.

For example, when installing or upgrading to SAM 6.3 and IPAM 4.3.2, any hotfixes for SAM 6.3 are installed. You must install the hotfix for IPAM manually.

Repeat installing on all Additional Polling Engines and then on all Additional Web Servers in your environment.

Activate the Additional Polling Engine licenses.

  1. Click Settings > All Settings > Polling Engines.
  2. Click Download Installer Now.
  3. Run the installer on the computer you want to use as your additional polling engine or website.
  4. Enter the main Orion server credentials.
  5. Choose either Additional Polling Engine or Additional Website. If you want to install a backup server for High Availability, view SolarWinds High Availability requirements first.
    The packages are downloaded from the main Orion server.
  6. Follow the onscreen instructions to complete your installation and configuration.

Activate Additional Polling Engine licenses

  1. In the Orion Web Console, click Settings > All Settings > License Manager.
  2. Locate the license in the License Manager, click Activate, and complete the activation.

    The Additional Polling Engine license is activated. Review the polling engine it is assigned to, and re-assign the license if necessary.

When finished, specify nodes to be polled by the Additional Polling Engine.
