VMware Hosts View

These displays present performance and utilization data for hosts running on one or all clusters and present utilization data for a specific host running virtual machines. Clicking VMware Hosts from the left/navigation menu opens the VMware Hosts Table display, which shows a tabular view of the utilization data for all hosts running on one or on all clusters. The option available under VMware Hosts is:

• Single VMware Host: Opens the VMware Host Summary, which shows utilization data for a specific host running virtual machines.

 

VMware Hosts Table

View the utilization data for all hosts running on one cluster or on all clusters. Each row in the table contains data for a particular host. Click a column header to sort column data in ascending or descending order. Double-click on a table row to drill-down to the VMware Host Summary display and view metrics for that particular host.

 

Note: Fields/columns with an asterisk (*) at the end of the field/column definition contain data that is provided by the VMWare vSphere. Refer to VMWare vsphere documentation (http://pubs.vmware.com/vsphere-65/index.jsp#com.vmware.wssdk.apiref.doc/mo-types-landing.html) for more information regarding these fields

VMware Host Summary

Clicking Single VMware Host in the left/navigation menu opens the VMware Host Summary display, which allows you to view the number of virtual machines running on a particular host, the most recent utilization data for the host, and the trend data for the host over a specified time range. Clicking on the information boxes at the top of the display takes you to the VMware Hosts Table display, where you can view additional host data.

In the trend graph region, you can select from Utilization, Disk, Network, or Network Loss. Utilization traces CPU and Memory usage percentage over a specified period of time. Disk traces disk reads, disk writes, CPU used percentage, and memory used percentage over a specified period of time. Network traces net transactions received and transmitted, as well as CPU and Memory usage percentage over a specified period of time. Network Loss traces the number of packets received and transmitted over a specified period of time.

Clicking the Critical/Warning link at the bottom of the display opens the Alerts Table by Component display.

 

Note: Fields/columns with an asterisk (*) at the end of the field/column definition contain data that is provided by the VMWare vSphere. Refer to VMWare vsphere documentation (http://pubs.vmware.com/vsphere-65/index.jsp#com.vmware.wssdk.apiref.doc/mo-types-landing.html) for more information regarding these fields.

Log Scale

Select to enable a logarithmic scale. Use Log Scale to see usage correlations for data with a wide range of values. For example, if a minority of your data is on a scale of tens, and a majority of your data is on a scale of thousands, the minority of your data is typically not visible in non-log scale graphs. Log Scale makes data on both scales visible by applying logarithmic values rather than actual values to the data.

 

 

Time Settings

Select a time range from the drop down menu varying from 5 Minutes to Last 7 Days. By default, the time range end point is the current time.

 

To change the time range, deselect the now toggle, which displays some additional date fields. You can click the left and right arrow buttons to decrease the end time by one time period (the time selected in the Time range drop down) per click, or you can choose the date and time from the associated calendar and clock icons. You can also enter the date and time in the text field using the following format: MMM dd, YYYY HH:MM:ss. For example, Aug 21, 2018 12:24 PM. Click the now toggle to reset the time range end point to the current time.
