Why following Widgets didn’t appear in “Monitor Tab” of managed server device? “Air Flow”, ”Outlet Temperature”, ”CPU Load”, ”I/O Load”, ”Memory Load”, ”CUPS Load”

That depends on Intel Node Manager (NM) version on the managed servers. For servers with NM v3.0, by default QSM auto displays these widgets. For servers with NM v2.0, QSM auto hides these widgets, because Intel NM v2.0 doesn’t provide these values.
