Store and Delete Daily Data Files

Each night at midnight (00:00:00), each data collection process closes the current file, deletes any expired files, and creates the next day's file. Use the ADVISE COLLECT SHOW SCHEDULE command to display the number of days occurring between file creation and deletion. The default expiration time is seven days. Use the ADVISE COLLECT MODIFY/DELETE_AFTER command to modify this time. For more information about the ADVISE COLLECT command, see the chapter “Performance Agent Commands.”
