    Detecting when a VM is vMotioned

    Here's the problem - we have a series of RHEL and Windows VMs that are hosted in a VMware DRS/HA cluster configuration. As 'guests' of the hosted (outsourced) environment, we do not have any access to the actual ESXi hosts nor can we use the vCenter console client to see the ESXi hosts nor the VMs on them. In the past few weeks, we have seen a number of our Windows and RHEL VMs encounter some heavy performance issues that last a second to as much as ten, similar to that of when a VM gets vMotioned. Our provider says that nothing like that has happened, however when we ask for an actual vMotion 'test' to be performed in real-time, the actual and seen result comes back just like before. All of our RHEL and Windows VMs have the latest VMware Tools installed on them. On the RHEL VMs, we have been toying around with the VMware Guest SDK, but it's rather limited on documentation and examples.

    Since we will have to run the Shinken application as a VM guest rather that outside the cluster/hosted environment, can Shinken detect when a vMotion has happen, either upon itself or to another guest RHEL or Windows VM, and send an alert?

    Hi,

    unfortunately, from now the only way Shinken known about VMotion is by asking the vcenter about it. I don't know another way of getting this :'(

    You can try to detect low the problem like increasing disk response time in the VM, but won't be like a real "you vmotion" it
