Host details

View detailed information about the components and resources that are related to a host.

To access the details page for a host, complete these steps:

From the Resources menu, click Hosts.
Right-click a host in the list and select View Details.

Overview

View the following charts that show space information about the host and performance information about volumes that the host accesses:

Response time

Response time provides you the information on the average number of milliseconds that took to service each read/write/total operation by the resource, for a particular component over a particular time interval.

Overall workload

The overall workload that the ESXi host has against the storage that it is using.

Most Active Storage System Volumes

The performance data for the volumes that are most active on the storage systems. The chart shows performance data that was collected about the most active volumes that the host accesses on the storage systems.

All the above charts can be viewed for the following metrics and the metrics which are specific to chart are shown with carousel.

Table 1. Chart metrics
Metric	Definition
Read Cache Hits	Percentage of cache hits for both sequential and nonsequential read operations, for a particular component over an interval.
Response Time	The average number of milliseconds for a resource to respond to a read or a write operation.
Volume Utilization	The average percentage of time that the volume is busy.
I/O Rate	The average number of I/O operations per second that are transmitted between the resources and the component. This value includes both read and write operations.
Data Rate	The average rate at which data is transmitted between the resources and the component. The rate is measured in MiB per second and includes both read and write operations.

Tip:

The charts show data that was collected about the host during the last 30 days. If no data was collected, the charts are blank. If data collection was interrupted during the last 30 days, a gap for the missing data is shown.
Hover over elements in the charts to view additional information.
To view different charts, click the name of a chart and select the chart that you want to view.
The selected charts are automatically displayed in the same positions the next time that you log on to the GUI and view the details of the resource.

Properties

View the attributes of the host, including information about its storage space. Use the General tab for host information, such as the hostname and IP address. Use the Volumes tab for drive space details.

Alerts and Alert Definitions

View the alerts that were generated when certain conditions were detected on a host on the Alerts page. Alerts are generated when the conditions that are specified on the Alert Definitions page are detected.

Use alert policies to manage the alert definitions and notification settings that apply to hosts. You can view, set, or create the alert policy for a host from the Alerts or Alert Definitions pages. The tasks that you can do depend on whether the host is managed by an alert policy.

Alert policy status	Tasks that you do
Managed by an alert policy	View the policy or set a different policy to manage the host. Click View Policy or Set Policy from the Policy Actions menu.
Not managed by an alert policy	Set a policy to manage the host or create a policy from the existing alert definitions. Click Set Policy or Create Policy from the Policy Actions menu. If you don't want to use a policy, you can edit the alert definitions. Click Alerts Definitions in the General section.
