cwoDreCacheStatsUsed
Module: CISCO-WAN-OPTIMIZATION-MIB
OID (symbolic): CISCO-WAN-OPTIMIZATION-MIB::cwoDreCacheStatsUsed
OID (numeric): 1.3.6.1.4.1.9.9.762.1.7.1.4
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: This object indicates the percentage of DRE disk space currently used out of the total space allocated for DRE cache. For example, if the disk space allocated for DRE cache is 972798MB and if this object indicates 1%, it means that 9727 MB is used and remaining approximate 963071 MB of disk space is free.
What is cwoDreCacheStatsUsed?
This read-only Gauge32, as a percentage, indicates how much of the DRE disk space currently used out of the total allocated for DRE cache, with the description's example of 972798MB allocated and a reported 1% meaning about 9727MB used and roughly 963071MB free. An admin monitors this to see how full the DRE cache actually is at any point, which affects how much eviction churn is happening. A cache reported near 100% used consistently would mean DRE is regularly evicting older data to make room for new, which an admin might address by allocating more disk space to the cache.
