Monitoring Disk Usage
Monitoring a host's controller or VM's virtual disk usage is similar in scope to monitoring network 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 individual 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:
- Use the vSphere Web Client to connect to a vCenter Server instance.
- Navigate to the Hosts And Clusters view.
- In the navigator, select an ESXi host.
This shows you the Summary tab in the Details section on the right.
- Click the Monitor tab, and the Performance sub-tab. Then switch...
