SYSMON authority provides the ability to take database system monitor snapshots of a database manager instance or its databases.
SYSMON authority is assigned to the group specified by the sysmon_group configuration parameter. If a group is specified, membership in that group is controlled outside the database manager through the security facility used on your platform.
SYSPROC.SNAP_WRITE_FILE takes a snapshot and saves its content into a file. If any snapshot table functions are called with null input parameters, the file content is returned instead of a real-time system snapshot.
