Plesk: Real memory usage reported by ‘Server Health’ does not match actual RAM
August 29th, 2011
Symptoms
Real memory usage reported by Plesk Health Monitoring Service (Home > Server Health > Memory) does not match RAM reported by utility ‘free‘.
Cause
RAM was updated after Parallels Plesk Panel was installed.
Plesk Health Monitor does not detect if the system configuration was changed after the initial installation.
Resolution
The problem will be fixed in future update of Parallels Plesk Panel that will be released after version 10.2.
To workaround:
# /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/scripts/setup-health-monitor.php
