The Composer server records user- and server-based activities in log files. These files can be used by Composer administrators to troubleshoot issues that may occur with the Composer server, for example, activities related to setting up data sources or creating visuals and dashboards. When Composer is installed in your network environment, a log file is created.
By default, activity logging is enabled, but some activities are not logged by default. For details, see the Activities Log Reference Sheet.
For more information about other Composer log files, see Composer Log Files.
