The vRealize Operations for Horizon broker agent is a Windows service that runs on a Horizon Connection Server host, collects Horizon inventory information, and sends that information to the Horizon adapter.
If your Horizon environment includes an events database, you must configure the broker agent to collect events from the database and send them to the Horizon adapter. You can optionally configure the broker agent to monitor only specific desktop pools in your Horizon environment.
You install the broker agent on one Horizon Connection Server host in each Horizon pod in your environment. You must install only one broker agent in each Horizon pod.
