You can automate ESXi VM inventory and snapshot retrieval across multiple hosts by running a pyATS script that connects via SSH to your ESXi testbed, executing commands on each host to list VMs and audit snapshot trees.

The best way to check for stale or deep snapshot chains in a VMware ESXi environment is to use a pyATS automation script that retrieves snapshot trees across your testbed and flags snapshots that may impact performance.

Yes, you need SSH access to the ESXi shells. The pyATS script executes hypervisor inspection commands remotely, requiring a defined testbed with device entries and appropriate SSH credentials to collect host-level information.

Yes, you can verify ESXi host readiness for a maintenance window using pyATS by collecting hypervisor health information and inspecting host-level data to ensure the environment is prepared for changes.

A key limitation is that fleet-wide VM discovery using pyATS requires a properly defined testbed with device entries for each ESXi host, and depends on consistent SSH access to all targeted ESXi shells to execute commands and report results.
