Updating Health Parameters After Hardware Change
Note that the hardware configuration of your Plesk server is specified in Health Monitor just once - during component installation. Further changes in hardware parameters are not propagated to Health Monitor. For example, if you increase the amount of RAM from 1 GB to 2 GB, Health Monitor will continue to show that the total RAM is 1 GB. To update Health Monitor data on server configuration, use Server Management > Health Monitoring > Detect Hardware Changes.
