tcpEStatsPathPreCongSumRTT

Module: TCP-ESTATS-MIB

OID (symbolic): TCP-ESTATS-MIB::tcpEStatsPathPreCongSumRTT

OID (numeric): 1.3.6.1.2.1.156.1.1.4.1.24

Node type: OBJECT-TYPE

Type: ZeroBasedCounter32

Access: read-only

Description: Sum of the last sample of the RTT (tcpEStatsPathSampleRTT) prior to the received congestion signals. This MUST be updated each time tcpEStatsPerfCongSignals is incremented, such that the change in tcpEStatsPathPreCongSumRTT divided by the change in tcpEStatsPerfCongSignals is the average RTT (over some interval) just prior to a congestion signal.

What is tcpEStatsPathPreCongSumRTT?

Running sum of the last RTT sample seen just before each congestion signal; dividing its change by the change in tcpEStatsPerfCongSignals gives the average RTT just prior to a congestion event.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.156.1.1.4.1.24
snmpwalk -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsPathPreCongSumRTT

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.156.1.1.4.1.24.1
