Looks like we just went over 5000 volumes in our cluster last night, and now I am getting this error when collecting some statistics, which we do via cron, and dump into a database:

pd-dd::*> statistics show -vserver pd -object volume -raw true -counter read_ops|write_ops|other_ops|read_data|write_data
There are no entries matching your query.

Warning: Failed to get statistics for object volume: The number of instances for this object exceeds the limit of 5000. Use the "-instance" parameter to limit the number of instances.

It would appear 5000 is some sort of magic internal number, after which CDOT will refuse to emit statistics.

Using the -instance parameter does nothting to help the situation, as that requires specifying the individual volume you are looking for.

I looked around under 'statistics settings' and 'statistics preset' but don't see any sort of control for this. 

Any ideas on how to get around this 5k limit?
