Connectors may be installed so that they are widely distributed across remote geographical locations. Therefore, having all logging information centralized is of great administrative value. This centralization 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 sources
Audit log. Provides information about the system’s day-to-day activities, which includes 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.
Error log. Provides information about conditions that are 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.
Identity Synchronization for Windows also writes all error log messages to the audit log to facilitate correlation with other events.
