Show Spot instances preemptions

The customer needs to have a way to see the preemptions (notified interruptions) of Spot instances.

Why do you need this feature?

need is a strong word, but you we offer the option to rebalance tests when VMs are preempted, its nice to know that it happened and to have stats on when it happened. If we know when / how many times it occurs, it could help us to fine tune our VM settings to reduce the occurrence of preemptions (choose different regions, machine sizes etc.). Also if a test run times out, which if test rebalancing did correctly happen, it is good to know that Spot VMs played no part in that, and an indicator would help us to know that the VM had not been preempted/rebalanced.

Why would it help your organization?

we have the ability to track the cost impact of using Spot VMs (via GCP), but not each occurrence
