Ich überwache insgesammt 6 VMs per sysstat und lasse mir dort unter anderem den Status des Filesystems und die Uptime anzeigen.
exemplarisch mal ein List von einem sysstat device.

Die Rückgabewerte werden dann von Notifies weiterüberwacht und es wird bei bedarf eine Pushnachricht ausgelöst.
Ein manuell ausgeführtes "get <name> update" funktioniert auch immer problemlos ohne Logeinträge.

Da die Probleme mit SYSSTAT erst nach dem letzten Update anfingen;
siehe hierzu https://forum.fhem.de/index.php/topic,119684.msg1141266.html#msg1141266;
habe ich nun zum Test das Attribut noSSH auf 0 gesetzt und über das Attribut ssh_user einen ssh berechtigen User und das zugehörige Passwort mitgegeben.

Seit dem trat bisher kein Fehler mehr auf.
