Swap | Balloon

Hello,

During the night our enviroment is allmost completly idle so we use DPM within vmware to shutdown hosts.
Sometimes there will be some ballooning and swapping, but during the day there is enough memory on the hosts to use "real" memory.
But as far as i know vmware will only "release" the swapped memory when the memory is accessed by the vmguest os.
So that means veeam keeps triggering alarms.

Is there a way around?

Hello Hans,

Well... you can configure suppression periods via alarm settings for the night time to avoid "expected" alarm messages.

In addition to this you may want to disable our predefined alarm and configure a new one which will be monitoring "Swap Out Rate" performance counter. This will allow you to be notified when VM starts swapping out memory, thus potentially causing performance problems.

Hope this helps!
