Outbound Utilization (\%)

Microsoft.SystemCenter.NetworkDevice.Interface.OutboundUtilizationThresholdMonitor (UnitMonitor)

Performance health state monitor that will show error state and alert when percentage outbound utilization exceed the defined threshold

Knowledge Base article:

Summary

Inbound Utliization Threshold Monitor

Causes

The outbound utilization of this device has exceeded the specified threshold, indicating a high level of bandwidth usage. This is determined based on the total count of octets received in relation to the current or optimal bandwidth of the interface.

Below are the details of the Object Identifier (OID) that is queried via an SNMP GET

Object

OID

Description

ifOutOctets

.1.3.6.1.2.1.2.2.1.16

The total number of outbound octets received by the device, including framing characters.

Resolutions

Below are some basic troubleshooting steps

  1. Raise the threshold on the monitor. This will allow for better "tuning" of the application to your environment. Take care no to raise the threshold too much as this could allow important events to go unnoticed.
