VPN Agent Availability (Aspect)

The System Center Mobile Device Manager (MDM) Mobile VPN agent is an ASP.NET HTTP handler associated with the Gateway Management Web site. This Web handler receives messages from Gateway Central Management (GCM) that contain VPN server configuration and blocked-device list settings. The Mobile VPN agent authorizes the message from GCM andA performs validation on the message. It then pushes the configuration to the VPN service runtime. Therefore, if the Mobile VPN agent is not available, then theA VPN runtime will not have the latest configuration as stored in the MDM database, or it may not have any working policy at all.

This aspect contains the VPN Agent Availability objects that you can monitor in the MDM Mobile VPN agent. These health monitors include the following detectors.

Green Health State

Event ID 12100: VPN_AGENT_INITIALIZED - Mobile VPN Agent successfully initialized and waiting for configuration updates.
Event ID 12109: VPN_AGENT_CONFIG_FILE_READ_SUCCEEDED - The Gateway Configuration file was read successfully.

Red Health State

Event ID 12101: VPN_AGENT_INITIALIZATION_FAILED - Mobile VPN Agent failed to initialize.
Event ID 12108: VPN_AGENT_CONFIG_FILE_READ_FAILED - The Gateway Configuration file is missing or invalid.
