When you add a new hard drive and increase available diskspace, add RAM to the server, or replace the CPU with
a more powerful one, these hardware changes are not reflected in Health Monitor. The old values of the hardware
capacity are still shown.

N.B.: questo problema è stato risolto in Plesk Panel 10.4.x

Se il problema dovesse verificarsi, ad ogni modo, lanciare il seguente comando:

# /usr/local/psa/bin/sw-engine-pleskrun
/usr/local/psa/admin/plib/scripts/setup-health-monitor.php
