Hyper-V monitoring: Here’s some tips!

Posted by on Sep 26, 2017 in Capacity Management, Nagios, Nagios-Plugins, NetEye | 0 comments

Network traffic monitoring is traditionally based on SNMP queries. This protocol generates statistics on the transmission of data across one or more network interfaces.

While network device queries still run through SNMP, using Microsoft Hyper-V monitoring requires the adoption of other approaches. One of the reasons is the network connection configuration itself: for example, many physical network interfaces of a Hyper-V device belong to a logical interface that can also distribute network traffic to multiple network devices, such as multiple switches. Another reason for using an alternative approach is that Microsoft has abandoned the maintenance of SNMP services on their operating systems.

Consider a physical network with the following configuration: a physical Hyper-V host has two active physical network connections that are connected to the network via two switches.

An important part of an IT Infrastructure is the UPS and Energy Stations that give the necessary power to your Infrastructure.
