I get these alerts on a virtual server. Everything shows fine in the Node Details page for this node, except 'Memory Used' Gauge. Under Disk Volumes, physical memory reports 50% utilization. Even performance monitor on the machine itself is not reporting those high numbers. Is there a way I can drill down into the settings and see exactly where the '89% Memory Used' gauge is getting its numbers, or the alerting aspect is getting the numbers to fire the alert?
