Foglight for Hyper-V 5.8 - User and Reference Guide

Hyper-V Explorer Monitor tab

The Hyper-V Explorer Monitor tab shows details of system resources consumption for a server or a virtual machine.

This tab appears in the Hyper-V Explorer when you select a server or a virtual machine on the Hyper-V Explorer Topology tab.

This tab is made up of the following embedded views:

Table 105. Connection and Throughput

Description	When exploring virtual machines, this view shows the dynamics of network traffic. For servers, this view also illustrates disk and memory input and output rates.
Data displayed	• Memory Swap In. The rate at which memory swap-ins occur. NOTE: This data only appears when exploring server details.

Hyper-V Explorer FAQts

This tab only appears when you are exploring individual clusters, servers, and virtual machines. It gives you answers to common questions related to the selected component. For example, when you select a Hyper-V server and open this tab you can quickly find out which servers in the cluster are consuming the least network bandwidth or have the most available memory.

Hyper-V Explorer FAQts tab

The Hyper-V Explorer’s FAQts tab shows answers to common questions related to a selected cluster, server, or a virtual machine.

This tab appears in the Hyper-V Explorer when you select a cluster, server, or a virtual machine on the Hyper-V Explorer Topology tab.

This tab is made up of the following embedded views:

This view provides an answer to the question selected in the Questions view. The answer appears in the following form:

Top x <objects of category>…

where x is the number of objects of the category you provided in the Categories view.

Specify x by entering a number. The answer is relative to the subset of the infrastructure you are viewing in the dashboard. For example, the top 5 servers are different for each individual cluster in the infrastructure.

This view lists the categories for which questions can be answered for you by Foglight for Hyper-V.

Click a category in the list to select it.

This view lists the questions, for the category selected in the Categories, that can be answered for you by Foglight for Hyper-V.

Click a question in the list to select it.

If the list of questions is long and you want to narrow it down, search for a particular text string using the Search Questions box.

Hyper-V Explorer Event Analytics

This tab only appears when you are exploring individual servers and virtual machines. It provides more details about the state of resource-related metrics over a selected time period and also shows any events that occur during that time-frame. This can give you a good idea of how the current resource consumption affects your environment as a whole. For example, a steady increase in memory consumption can often trigger memory utilization alarms, which typically indicates that you need to allocate more memory to the affected component.
