tcpConnectionProcess
Module: TCP-MIB
OID (symbolic): TCP-MIB::tcpConnectionProcess
OID (numeric): 1.3.6.1.2.1.6.19.1.8
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The system's process ID for the process associated with this connection, or zero if there is no such process. This value is expected to be the same as HOST-RESOURCES-MIB:: hrSWRunIndex or SYSAPPL-MIB::sysApplElmtRunIndex for some row in the appropriate tables.
What is tcpConnectionProcess?
This value gives the operating-system process ID of the application that owns a particular TCP connection, or zero if no such process can be identified, letting the connection's row be cross-referenced against process tables like HOST-RESOURCES-MIB's hrSWRunIndex. A system administrator uses this to trace a suspicious or resource-hogging connection back to the actual program responsible for it. For example, seeing tcpConnectionProcess return 4821 for a connection to an unexpected external address lets an admin look up process 4821 to identify which application opened it.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.6.19.1.8 snmpwalk -v2c -c public <target> TCP-MIB::tcpConnectionProcess
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.6.19.1.8.1 snmpget -v2c -c public <target> TCP-MIB::tcpConnectionProcess.1
