This video demonstrates how to install an additional polling engine.


Important: There are improvements in installing additional polling engines, additional web servers, and HA servers when using the Orion Scalability Engine Installer, available in Orion Platform version 2016.2 and later products (including NPM 12.0.1 and SAM 6.3).





  • Orion Platform version 2016 and above. Products on this Orion Platform version include NPM 12.0 and above and SAM 6.2.4 and above.

In this video, we’re going to walk through the steps to install an additional polling engine and connect it to your main Orion platform server.

Before you get started, you should first ensure that your Orion platform environment has been fully updated, and of course, double check the system requirements to ensure your new polling engine server will be up to its task.

You should also gather the SQL server details and credentials for where your Orion platform database is stored, as you will need them later.

Log into your customer portal, and look for the Additional polling engine package, then download the latest version to the newly created server.

Note: If you have a module that is NOT on the same version as the poller package, it is recommended to use the individual download for the products you own to install the additional poller.

Run the additional polling engine installer. Depending on the size of your environment, this process may take several minutes. You will be prompted to run a compatibility check to ensure that the polling package is compatible with your main server. Enter the IP address and your log in credentials.

When the compatibility check is completed, simply follow the prompts to continue the installation.

When the Setup Wizard has finished, you will be asked to license the product . This will pull your polling engine license from your customer portal and install it on your new server. Enter your details, including the license key for your product. You can find this on the customer portal, under License Management.

When the installation completes, the configuration wizard will automatically run. When prompted, enter in the credentials for your SQL server and the details of your existing Orion platform database.

This warning message is to be expected. Simply click 'Okay,' and then select your database from the drop down menu.

Click 'Okay.'

And click 'Okay' again to select your SQL account and enter your password.

This is a necessary step, so click 'Yes' and then 'Next' to start the configuration.

Once the configuration wizard is complete, your additional polling engine is ready to poll, but you’ll need to configure it to determine what it should poll.

Open the web console on the main polling engine – your additional polling engine will not have its own web console.

If you want to move a number of existing nodes over to your new polling engine to balance the polling load, navigate to Manage Nodes, and select the nodes you want to move. Use the ‘Change Polling Engine’ option from the drop down menu and choose the polling engine you would like to move these nodes to. You should always exercise caution when making changes like this, as there may be firewalls or security defined on your nodes or the network path allowing polling communication only from the main polling engine. Make sure any environmental adjustments have been made before migrating your nodes.

With an additional polling engine installed, you'll also have the option to run a discovery specifically from that engine – you’ll notice that in a multi-poller environment, you have the option to run the discovery from the polling engine of your choice.
