If the domain can access an existing Secure Agent, you can configure the domain to use the Secure Agent when you register the domain with Operational Insights. You can configure multiple domains within your organization to use the same Secure Agent.

If the domain doesn't have access to a Secure Agent, you must download and install a Secure Agent on a node within the domain. The Secure Agent must be installed on a machine that has access to the internet.

Note that if the Operational Insights service shuts down for more than 12 hours, the Secure Agent connection to the service times out. Manually restart the Secure Agent on the node to re-establish the connection.
