cwoDreCacheStatsDataUnitUsage
Module: CISCO-WAN-OPTIMIZATION-MIB
OID (symbolic): CISCO-WAN-OPTIMIZATION-MIB::cwoDreCacheStatsDataUnitUsage
OID (numeric): 1.3.6.1.4.1.9.9.762.1.7.1.5
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: This object indicates DRE disk space currently used by data unit. DRE stores the actual data as data units in data block and the metadata (chuck signature) in signature block.
What is cwoDreCacheStatsDataUnitUsage?
This read-only Unsigned32, in MB, indicates DRE disk space currently used specifically by data units, as opposed to the metadata (chunk signatures) stored separately in the signature block. An admin uses this alongside cwoDreCacheStatsSigblockUsage to understand the split between actual cached data content and its indexing metadata within the DRE cache. A data unit usage that's disproportionately small relative to signature block usage might indicate the traffic pattern involves many small or highly fragmented chunks.
