robopet3Memory usage alarm triggers for certain types of Virtual Machines in ESXi 6.x (2149787)
ESXi's active memory metric, despite being called "Memory Utilization" or "Memory Usage" in different parts of the UI, is in no way related to the in-guest memory metrics. It doesn't show how much guest OS memory is available nor how much guest memory is in an "active" working set or "resident". It is only used for making memory reclamation decisions in addition to other resource controls like shares, limits and reservation
