3.
In the Navigator, select an ESXi host. This will show you the Summary tab in the content
area to the right.
➢
4.
Select the Monitor
Performance subsection, and switch to Advanced view.
5.
Click the Chart Options link.
6.
Under Chart Options in the Chart Options dialog box, select the Network resource type
and the Real-Time display interval.
7.
Set the chart type to Line Graph.
8.
In the objects list, select the ESXi host as well as all the specii c NICs.
9.
Select the Network Data Transmit Rate and Network Packets Transmitted counters.
10.
Click OK to apply the changes and return to the Performance tab.
Very much as with the previous example for a VM, these two counters will give you a win-
dow into how much network activity is occurring on this particular host in the outbound direc-
tion for each physical NIC. This is especially relevant if you want to see different rates of usage
for each physical network interface, which, by dei nition, represent different virtual switches.
Now that you've examined how to monitor CPU, memory, and network usage, there's only
one major area left: monitoring disk usage.
Monitoring Disk Usage
Monitoring a host's controller or VM's virtual disk usage is similar in scope to monitoring net-
work usage. This resource, which represents a controller or the storing of a VM's virtual disk on
a type of supported storage, isn't restricted by CPU or memory mechanisms like reservations,
limits, or shares. The only way to restrict a VM's disk activity is to assign shares on the indi-
vidual VM, which in turn may have to compete with other VMs running from the same storage
volume. vCenter Server's charts come to our aid again in showing actual usage for both ESXi
hosts and VMs.
Perform the following steps to create a host chart showing disk controller utilization:
1.
Use the vSphere Web Client to connect to a vCenter Server instance.
2.
Navigate to the Hosts And Clusters view.
3.
In the Navigator, select an ESXi host.
This shows you the Summary tab in the Details section on the right.
4.
Select the Performance tab, and switch to the Advanced view.
5.
Click the Chart Options link. This opens the Chart Options dialog box.
6.
Under Chart Options, choose the Real-Time display interval for the Disk resource type.
7.
Set the chart type to Line Graph.
