What is sfpsTopologyDirStatsNodeLongestChain?
The length of the longest hash-bucket chain currently in the node table. The source DESCRIPTION is blank, but by analogy with sfpsTopologyDirStatsNodeCollisions (which this field sits right next to) it's a hash-table health metric: a long chain means many nodes fell into the same bucket, which slows down lookups for those entries.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.4.2.2.3.11.21 snmpwalk -v2c -c public <target> CTRON-SFPS-DIRECTORY-MIB::sfpsTopologyDirStatsNodeLongestChain
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.4.2.2.3.11.21.1 snmpget -v2c -c public <target> CTRON-SFPS-DIRECTORY-MIB::sfpsTopologyDirStatsNodeLongestChain.1
