tcpEStatsPerfZeroRwinSent
Module: TCP-ESTATS-MIB
OID (symbolic): TCP-ESTATS-MIB::tcpEStatsPerfZeroRwinSent
OID (numeric): 1.3.6.1.2.1.156.1.1.3.1.25
Node type: OBJECT-TYPE
Type: ZeroBasedCounter32
Access: read-only
Description: The number of acknowledgments sent announcing a zero
receive window, when the previously announced window was not zero.
What is tcpEStatsPerfZeroRwinSent?
Count of ACKs sent announcing a zero receive window after previously advertising a nonzero one; each increment means the local receiver told the remote sender to stop, a sign of local buffer exhaustion or a slow-reading application.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.156.1.1.3.1.25 snmpwalk -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsPerfZeroRwinSent
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.156.1.1.3.1.25.1 snmpget -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsPerfZeroRwinSent.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> tcpEStatsPerfZeroRwinSent.1
