The Broker Server Log
The Broker Server log receives messages from both the Broker Monitor and Broker Server. These messages represent significant events or unusual conditions that occur on the Broker Server. For example, when Broker Monitor starts a Broker Server or detects that Broker Server has stopped running, it writes a message to the log.
As an administrator, the information in the log is useful for troubleshooting purposes and for alerting you to abnormal operating conditions that arise on Broker Server.
