cwoDrePerfStatsEncodeCompressionRatio
Module: CISCO-WAN-OPTIMIZATION-MIB
OID (symbolic): CISCO-WAN-OPTIMIZATION-MIB::cwoDrePerfStatsEncodeCompressionRatio
OID (numeric): 1.3.6.1.4.1.9.9.762.1.7.2.1
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: This object indicates the total compression ratio provided by all the DRE components - DRE, LZ and PLZ (if applicable), during the encoding process. It is the ratio of the number of bytes entering the DRE module (from LAN side) and the number of bytes exiting the DRE module (from WAN side). This object indicates the value that is calculated since the last time the counter was cleared. The calculation is not based on per-connection or per-peer basis.
What is cwoDrePerfStatsEncodeCompressionRatio?
This read-only Gauge32, as a percentage from 1 to 100, indicates the total compression ratio provided by DRE, LZ, and PLZ (if applicable) during encoding, calculated as bytes entering the DRE module from the LAN side versus bytes exiting toward the WAN side, and per the description this is a since-last-reset aggregate, not per-connection or per-peer. An admin uses this as the headline metric for how effectively outbound WAN traffic is being shrunk by the optimization stack. A dropping compression ratio over time, even with stable traffic patterns, would suggest the data being sent has become less redundant or the DRE cache is undersized to catch repeats.
