cwoDreCacheStatsSigblockAge
Module: CISCO-WAN-OPTIMIZATION-MIB
OID (symbolic): CISCO-WAN-OPTIMIZATION-MIB::cwoDreCacheStatsSigblockAge
OID (numeric): 1.3.6.1.4.1.9.9.762.1.7.1.10
Node type: OBJECT-TYPE
Type: SnmpAdminString
Access: read-only
Description: This object indicates the age of oldest signature in the
sigblock. DRE stores the actual data as data units in the data
block and the metadata (chuck signature) in signature block.
If a new signature should be written to the sigblock when it is
full, then the oldest signature currently present in the
sigblock will be evicted. So this object would indicate the age
of the oldest signature present in the DRE cache. It takes the
format of
What is cwoDreCacheStatsSigblockAge?
This read-only SnmpAdminString indicates the age of the oldest signature in the sigblock, formatted as <x>d... per the description, reflecting how long signature metadata survives before being evicted when the sigblock fills up. An admin compares this against cwoDreCacheStatsDataUnitAge to see whether the data block or the signature block is the tighter constraint on cache retention. If sigblock age is consistently much shorter than data unit age, an admin would suspect the signature block is undersized relative to the data block for the current traffic mix.
