Connectors may be installed so that they are widely distributed across remote geographical locations; therefore, it is of great administrative value to have all logging information centralized, which allows the administrator to monitor synchronization activity, detect errors, and evaluate the health of the entire system from a single location.
Verify that the system is running correctly
Detect and resolve individual component and system-wide problems
Audit individual and system-wide synchronization activity
Track a user’s password synchronization between directory environments
The audit log provides information about the system’s day-to-day activities, which includes important events such as a user’s password being synchronized between directories. You can control the level of information that is logged in the audit log by increasing or decreasing the detail provided in the log messages.
Identity Synchronization for Windows also writes all of the error log messages to the audit log to facilitate easy correlation with other events.
The error log provides information about conditions qualified as severe errors and warnings. All error log entries are worthy of attention, so you cannot prevent errors from being logged. If an error condition takes place, it will always be documented in the error log.
