Custom Messages for Logging
Integration Services provides a rich set of custom events for writing log entries for packages and many tasks. You can use these entries to save detailed information about execution progress, results, and problems by recording predefined events or user-defined messages for later analysis. For example, you can record when a bulk insert begins and ends to identify performance issues when the package runs.
The custom log entries are a different set of entries than the set of standard logging events that are available for packages and all containers and tasks. The custom log entries are tailored to capture useful information about a specific task in a package. For example, one of the custom log entries for the Execute SQL task records the SQL statement that the task executes in the log.
All log entries include date and time information, including the log entries that are automatically written when a package begins and finishes. Many of the log events write multiple entries to the log. This typically occurs when the event has different phases. For example, the ExecuteSQLExecutingQuery log event writes three entries: one entry after the task acquires a connection to the database, another after the task starts to prepare the SQL statement, and one more after the execution of the SQL statement is completed.
