Trend Micro Apex One keeps connection verification logs to allow you to determine whether or not the Trend Micro Apex One server can communicate with all of its registered agents. Trend Micro Apex One creates a log entry each time you verify agent-server connection from the web console.
To keep the size of logs from occupying too much space on the hard disk, manually delete logs or configure a log deletion schedule. For more information about managing logs, see Log Management.
