Major Description
I would find it useful for interactive monitoring and debugging to be able to issue a gfsh command that prints the current value of a statistic. Currently, some statistics are available with the gfsh show metrics command, but not all. And I don't want to have to use the API to capture a value that I need while I'm trying to interactively debug a cluster.
The particular case/statistic I want to see is GatewayStatistics eventQueueSize, which doesn't appear to be accessible by using gfsh show metrics command. My use case has to do with migrating data from one cluster to another. I want to enable a gateway sender that will "push" my region entries to the other cluster as entries are touched. But, once I've completed touching each entry to be migrated, I need to know that sender's queue has emptied to be able to call my migration complete.
