DRS is automatically moving VMs between ESX hosts in our cluster. How can I monitor these?
You need a VMWare Virtual Center server to do this. Instead of adding the VM sensors to the ESX host server device, create a device for your Virtual Center Server and create the VM sensors for that device.
Could you please explain more in details, I tried add device for VCenter and add VMs sensors, but unsuccessfully.
Create the Virtual Center server as a device.
in the settings edit the credentials for VMware servers and use the logon credentials you use in your vSphere Client to log on to the vCenter Server.
Now select add sensors -> Virtual Servers -> VMware Virtual Machine
you should get a list of all the available virtual machines
We're monitoring our guests in this manner, but we have an issue with it. Whenever we set our scanning interval lower than five minutes, many of the guest sensors stay in unknown status. This devalues the sensors since a five minute scanning interval is neither good for alerting promptly if a server goes down not is it good for tracking historical data. Any idea what we can do to get a lower scanning interval to work consistently?
how many VMs are you running?
You simply can not send too many requests to the VMware SOAP API at the same time.
The requests are processed serial, not parallel.
Is there a similar solution von VMs on Hyper-V (without SCVMM)? I have a smaller customer with two Hyper-V 2012 Servers and moving VMs between them results in Errors in PRTG.
no, sorry, this does nor work without an scvmm.
