To change the default swapfile location for the host select the host, click the Configuration tab and Virtual Machine Swapfile Location. It may be likely that your host is configured to use a different datastore for all VMs by default and it is just taken up by swap files at this point. As far as cleaning up that datastore, you can right-click it and Browse and poke around to see what kind of files are taking up the space. Select one of the other options ("Always store with the virtual machine" is recommended and will probably work for you since that datastore has a lot of free space). Frequently, I recommend creating some custom alarms and configuring specific actions on some alarms to meet customer needs. Right-click Datastore usage on disk alarm and click Edit. Right-click the VM and go to Edit Settings > Options tab > Swapfile location. As part of many of my vSphere related professional services engagements, such jumpstarts, designs, upgrades and health-checks, I typically address the alarms provided by VMware vCenter Server. Select the vCenter Server that is having the issue and click the Alarms tab. Are any of the datastores full or very close to it? The swap file may be located on a full datastore even if the VM is on another datastore and if the host cannot create the swap file, the VM will not boot. No graph a look at all of the datastores visible to the host (in vSphere, select the host > Configuration tab > Storage).

Discovery identifies and classifies information about VMware vCenter. The alert value can be set to either Yes or No. If the metric value satisfies the condition defined along with Critical Threshold value, then a notification is sent to the user. If the metric value satisfies the condition defined along with Warning Threshold value, then a notification is sent to the user. Frequency is the interval in which you want to probe and collect metric data from the target device/resource.Metric Parameters Metric Parameters Parameter It will not ask user to select any instance (s) while assigning it to a device. How to Apply: This template is All instance selection based. vCenter device should be reachable from Gateway. This template is used to capture the VMware alarms present in vCenter.
