You can create an alarm that will fire if a specific metric surpasses a threshold.

thanks for your replay
I will detail even more my idea
I'm working on a project to implement a private / public hybrid cloud solution
the solution is expected to allow a virtualized computer system, initially deployed in private cloud mode (VMware), to expand when it experiences point load peaks
to a public cloud and then back to the private cloud once the load is down (scale out / scale in).
We use vmware for the private cloud.
We use openstack for the public cloud.
The question is: is there a tool or a set of tools in vmware that can help me realize my project?
I am reading the vmware documentation and I am falling on three tracks:
1-- I can create an alarm in vsphère that triggers when exceeding a certain threshold of RAM example 80%.
2- using powerCLi an image will be clone and deploy in opensatck
3- I use maybe 'vmware integrated openstack'
I do not know yet the feasibility of his tools for my project
I'm counting on you to tell me to the right tools in vMware product that may be useful in my case.
For the return path (go back to the private cloud once the load drops) I'll see that side public cloud (openstack)
Thank you for sharing documentation or links to the documentation with me
Sorry, but I don't think there are currently any scripts to do that move/clone.
In concept you have to inject drivers, convert the VMDK to Ceph...
See How to migrate from VMware and Hyper-V to OpenStack - Superuser for a more detailed list of the steps involved.
Did you raise the question in the Integrated OpenStack community as well?Blog: http://lucd.info | Twitter: @LucD22 | PowerCLI Reference co-author: http://tinyurl.com/hkn4glz
precisely I do not think that all the work will be done by script
but I am in the research phase of how:
when the load is waiting (eg 80% use of RAM) on my first VM (vmware-private cloud) I switch traffic to another machine (in openstack - public cloud)
my first step is to create an alarm that triggers a traittemnt
the idea of not migrating all to opensatck - it's just doing some sort of load balancing or tilting between the two clouds
scal in scale out
