tcpEStatsPathRTTVar
Module: TCP-ESTATS-MIB
OID (symbolic): TCP-ESTATS-MIB::tcpEStatsPathRTTVar
OID (numeric): 1.3.6.1.2.1.156.1.1.4.1.12
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: The round trip time variation used in calculation of the RTO. See RTTVAR in [RFC2988].
What is tcpEStatsPathRTTVar?
The RTT variance estimate (RTTVAR) used together with the smoothed RTT to compute the retransmission timeout; a large value here means path latency is jittery, which pads out the RTO.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.156.1.1.4.1.12 snmpwalk -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsPathRTTVar
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.156.1.1.4.1.12.1 snmpget -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsPathRTTVar.1

Create custom SNMP monitor using the TCP-ESTATS-MIB::tcpEStatsPathRTTVar OID value, configure state conditions and alerts, and monitor any vendor-neutral, standards-based MIB, hosts/servers/network devices running a TCP/IP stack (extended TCP performance diagnostics) from a single console.
