Cluster::> set advanced

Warning: These advanced commands are potentially dangerous; use them only when directed to do so by NetApp personnel.

Cluster::*> storage aggregate object-store profiler start -node Cluster-01 -object-store-name S3Bucket

Warning: This is a CPU intensive command. It is recommended to run this command when the system is under 50% CPU utilization. This command will issue 2500 PUT requests for a time period of 60 seconds, followed by maximum GET requests to
     the object store for a time period of 180 seconds. This may result in additional charges to your object store account. Do you want to continue?
Do you want to continue? {y|n}: y

Warning: Object store profiler tests the connection to the object store and is not reflective of FabricPool PUT throughput at steady state.
Error: command failed: Initializing the object store profiler on node "Cluster-01" for object store "S3Bucket" failed. Reason: Skewed time. Wait a few minutes and try the command again.
