udpHCInDatagrams
Module: UDP-MIB
OID (symbolic): UDP-MIB::udpHCInDatagrams
OID (numeric): 1.3.6.1.2.1.7.8
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The total number of UDP datagrams delivered to UDP users, for devices that can receive more than 1 million UDP datagrams per second.
Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by discontinuities in the value of sysUpTime.
What is udpHCInDatagrams?
This object is a 64-bit running total of UDP datagrams the device has delivered up to local applications, sized to avoid wrapping on very high-throughput systems passing more than a million UDP datagrams per second. An admin polls this, and diffs successive readings, to track inbound UDP traffic volume and trends, watching for discontinuities that the MIB notes can occur after a management-system restart or similar reinitialization. For example, watching this counter increase by roughly 2 million between two 5-minute polls would indicate about 6,700 UDP datagrams per second of inbound traffic.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.7.8 snmpwalk -v2c -c public <target> UDP-MIB::udpHCInDatagrams
Get a specific instance (index 1):

Start monitoring vendor-neutral, standards-based MIB, any host/server/network device running a UDP/IP stack (datagram counter/listener-endpoint status) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the UDP-MIB::udpHCInDatagrams OID value, configure state conditions and alerts, and monitor any vendor-neutral, standards-based MIB, any host/server/network device running a UDP/IP stack (datagram counter/listener-endpoint status) from a single console.
