How it works...

The OMS Gateway is simply an HTTP forward proxy that makes connections on behalf of clients through HTTP CONNECT tunneling. In this case, the OMS agent computer forwards its TCP connection to the OMS Gateway, which tunnels the TCP connection to the OMS service endpoints. This tunneling mechanism means that the data is sent directly from the OMS Gateway to the OMS endpoints without being analyzed.

The OMS Gateway can be used with both OMS agents that are configured to directly connect to an OMS workspace, and an Operations Manager (SCOM) management group that is integrated with OMS. With directly connected OMS agents, the data is sent to the OMS Gateway, which then transfers the data directly to OMS in the manner previously described. When configured for use with an SCOM management group, the proxy information defined for the management group is distributed automatically to every agent-managed computer that is configured as an OMS-managed computer, even if that setting isn't defined.

Depending on the solution(s) configured in OMS, the agent will then collect the relevant data and either send it to the management server or, in the case of high-volume data, such as performance metrics and security events, directly to the OMS endpoints via the OMS Gateway.
