Session and Workflow Logs Overview

Session and Workflow Logs Overview

The Service Manager provides accumulated log events from each service in the domain and for sessions and workflows. To perform the logging function, the Service Manager runs a Log Manager and a Log Agent. The Log Manager runs on the master gateway node. The Integration Service generates log events for workflows and sessions. The Log Agent runs on the nodes to collect and process log events for sessions and workflows.
Log events for workflows include information about tasks performed by the Integration Service, workflow processing, and workflow errors. Log events for sessions include information about the tasks performed by the Integration Service, session errors, and load summary and transformation statistics for the session.
You can view log events for workflows with the Log Events window in the Workflow Monitor. The Log Events window displays information about log events including severity level, message code, run time, workflow name, and session name. For session logs, you can set the tracing level to log more information. All log events display severity regardless of tracing level.
The following steps describe how the Log Manager processes session and workflow logs:
  1. The Integration Service writes binary log files on the node. It sends information about the sessions and workflows to the Log Manager.
  2. The Log Manager stores information about workflow and session logs in the domain configuration database. The domain configuration database stores information such as the path to the log file location, the node that contains the log, and the Integration Service that created the log.
  3. When you view a session or workflow in the Log Events window, the Log Manager retrieves the information from the domain configuration database to determine the location of the session or workflow logs.
  4. The Log Manager dispatches a Log Agent to retrieve the log events on each node to display in the Log Events window.
To access log events for more than the last workflow run, you can configure sessions and workflows to archive logs by time stamp. You can also configure a workflow to produce text log files. You can archive text log files by run or by time stamp. When you configure the workflow or session to produce text log files, the Integration Service creates the binary log and the text log file.
You can limit the size of session logs for long-running and real-time sessions. You can limit the log size by configuring a maximum time frame or a maximum file size. When a log reaches the maximum size, the Integration Service starts a new log.
