If specified instance ID is higher than the size of the maximum number of snapshot
instances configured, the following error message is displayed on the console:
%Error: Instance Id is not valid. Configured max snapshot
instances are <max-instances>
If you configured the maximum number of instances as 5 and attempt to view the
buffer statistics tracking details for the instance ID of 6, the aforementioned error is
shown.
