About event logs

Event logs contain a record of specific system or workflow-related events for each isolated region. This type of logging is useful for tracking workflow activity.

Each event that is logged is part of an event category, and has an associated event number.

Analyzing event logs

After events are logged to the database, you can access and analyze them in the following ways:

Using the administration console
Using a user-defined application that calls the log query APIs
Using a comma-separated (.CSV) text file that is created by vwlog

How workflow system stores event information

The event log DefaultEventLog is automatically created for each isolated region. As the system administrator, you set the event logging options, which represent event categories in the following way: if you enable logging for a category, the occurrence of any event within that category in the region generates a log message.

Important: A message can also be logged if a Log system function is run for a workflow; however, the event log category User-defined message 1 must be enabled.

For the database fields that are defined for the event log, a log message record includes any applicable database field values. Specifically, for any workflow field that corresponds to a database field, the current value of the workflow field is automatically stored in the event log record.

Event log database maintenance

The event log database tables can grow quickly with event logging enabled for the isolated region. The system administrator must periodically extract the logged messages from the event log database and save them in the history file.
