The Physical Memory Alert rule sends an alert when the percentage of physical memory that is free goes below a user-defined threshold.
The Physical Memory Alert rule includes the following rule-specific settings:
User Threshold — Specify the percentage of free physical memory below which an alert is sent. The default is 15.
Sampling Frequency — Specify the frequency at which physical memory is checked in seconds. The default is 30.
