In Adaptive Server version 12.5.3, some of the most commonly used monitoring tools have been enhanced.
Using sp_sysmon with the noclear option
became the default behavior in Adaptive Server version 15.0.1 and
later. For more information on updates to sp_sysmon,
see “Changes to sp_sysmon” in Chapter 21, “New Features in Adaptive Server 15.0.1.”
