While the server is operational, it will generate a set of events based on performed operations. These events can be used for auditing and logging purposes.
An event can be logged into a log file, and the log file can be used later for audit tasks.
Those conducting an audit or administrators wishing to be further informed of the audit trail can cross-reference Event IDs (such as 20137) found in the logs.
To be further informed about the event ID's group (such as informational for the 20137 event ID), search for the name in the Server Event Group page.
For configuring the server to react when an event occurs, please see the dedicated page.
