Data Mover provides status monitoring through the command-line interface's status command. For more information, see the status command section.
Each Data Mover component maintains rolling log files for internal health monitoring. They are dmAgent.log, dmCommandLine.log, and dmDaemon.log for the agent, command line, and daemon, respectively. The maximum size for these files is 10MB. When 10MB is reached, up to three additional backup files are created. For example, dmAgent.1, dmAgent.2 and dmAgent.3 are created for the agent. Similar backup files would be created for the command line and daemon.
These log files are needed to diagnose problems should they arise, therefore do not delete the files.
