dxCacheSequentialScans
Module: DX-MIB
OID (symbolic): DX-MIB::dxCacheSequentialScans
OID (numeric): 1.3.6.1.4.1.3327.21.3.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Number of searches requiring a sequential scan of the cache.
What is dxCacheSequentialScans?
This counter tracks the cumulative number of searches that required a full sequential scan of DxCache rather than an indexed lookup. An admin watches this because a high rate of sequential scans signals inefficient search filters or missing indexes, hurting cache performance. For example, a spike in sequential scans coinciding with slow search response times could point an admin toward an unindexed or overly broad search filter.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3327.21.3.5 snmpwalk -v2c -c public <target> DX-MIB::dxCacheSequentialScans
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3327.21.3.5.1 snmpget -v2c -c public <target> DX-MIB::dxCacheSequentialScans.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> dxCacheSequentialScans.1
