---------------------------------------------------------------
The attached patch provide JMX metrics per storage type.
The following information is provided for each storage type in the cluster
{capacityTotal, capacityUsed, capacityRemaining, blockPoolUsed, nodesInService,
numBlocks}
Sample JMX output:
{code}
"TieredStorageStats" : "
{\"ARCHIVE\":{\"capacityTotal\":1498254102528,\"capacityUsed\":12288,\"capacityRemaining\":981672161280,\"blockPoolUsed\":12288,\"nodesInService\":3,\"numBlocks\":0},
\"DISK\":{\"capacityTotal\":1498254102528,\"capacityUsed\":12288,\"capacityRemaining\":981672161280,\"blockPoolUsed\":12288,\"nodesInService\":3,\"numBlocks\":0}}"
