View messages in the Windows event log

When PI Message Subsystem is not available, Data Archive components write messages to the Windows event log. You can view these messages with Windows Event Viewer if you are running Data Archive as a service, or with the command windows if running Data Archive interactively. When PI Message Subsystem starts, it merges messages from the Windows event log into the message log.

Note: During startup, some components might write messages to the Windows event log before PI Message Subsystem starts.
