Hardware changes are not reflected in Health Monitor in Plesk
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.
Cause
New hardware configuration values are not automatically re-calculated by Health Monitor.
Run the following command to make Parallels Plesk Panel Health Monitor recognize recent hardware configuration changes:
"%plesk_bin%\php.exe" -d auto_prepend_file="" "%plesk_dir%\admin\plib\scripts\setup-health-monitor.php"
In Linux
/usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/scripts/setup-health-monitor.php
