Folks,
May I know what's if using Solarwinds Orion Polling as opposed to using Agent is faster and lighter ?eg. does not consume much resource on the server side?
Because I'm currently cutting over to not using Solarwinds agent anymore due to the remote agent restart requirement after upgrading Orion Platform, but using the Polling method.
Is there any benefits when using agent instead of the normal polling?
Port use by each methods:
5x ports SW agent:https://documentation.solarwinds.com/en/Success_Center/orionplatform/content/core-agent-requirements-sw476.htm#ports17x ports SAM Polling: https://documentation.solarwinds.com/en/Success_Center/orionplatform/content/core-orion-requirements-sw1916.htm#Server
See if this helps

You are confusing things a bit.For the Solarwinds Agent, if you care to do your agent deployment directly on the server with an RDC session rather than push it from a Polling Engine or Core, then there is only one port required to be open towards the polling engines or core, and that is the encrypted traffic port of 17778.Your second link there is not for WMI polling of targets, but is for a polling engine to maintain peer connection with the Orion Core and other pollers.
For WMI polling, you are going to need more that one port open. You need the WMI port 135 open from the polling engine or core towards your target server. However, you are going to need to have open almost every port over 1024 open for WMI replies unless you go and specifically configure WMI for reduced port usage. Generally it will still need ports 49152-65535. Service overview and network port requirements - Windows Server | Microsoft Docs
