e have few esxi ver5.1.
HA and DRS are enabled. The DRS is set to full automation.
We are monitoring the vm using third party monitoring tool which monitor cpu , memory , dcc using WMI. in the meantime i enabled vcenter alert for esxi host and vms. We get alert for vm and esxi host for memory. I expect the vm to migrate to another esxi host when we get these alerts at 90% or more believing that memory has been taken, but it does not happen. That is, the vm still on a esxi host which is in 90% memory utilization.
1- Why a vm does not get vacated from an exit host which memory almost being used by guest vms?
2- How do i find out a vm goes into balling effect?
