Host Statistics Report

The objective of this report is to allow the administrator to analyze resource consumption for monitored hosts by summarizing performance metrics per computer for a period of time. This report answers questions such as:

  • What hosts have the highest CPU consumption?
  • What hosts have the highest disk read/write latency?

The data grid in this report displays the following details for every computer:

  1. Host name - the target computer on which the session was established
  2. Version – Hypervisor version
  3. CPU Cores – Total number of CPU cores on the host
  4. Installed Memory – The amount of physically installed RAM on the host
  5. vCPU/pCPU Ratio – Shows the ration of the total number of vCPUs assigned to all VMs running on a host, to the number of physical cores
  6. CPU Usage – Actively used CPU cycles of the host as a percentage of the total available CPU cycles on the host
  7. Consumed Memory – Includes memory used by the Service Console, the VMkernel, vSphere services plus the total consumed metrics for all running virtual machines
  8. Running VM Count – Number of VMs running on this host
  9. Datastore R/W IOPS – Aggregated number of IO operations on the datastore. The value displayed belongs to the datastore with the highest number of IOPs (needs to be explicitly enabled on XenServer)
  10. Datastore Read Latency – Average amount of time for a read operation from the VMware datastore. The value displayed belongs to the datastore with the highest read latency
  11. Datastore Write Latency – Average amount of time for a read operation from the VMware datastore. The value displayed belongs to the datastore with the highest write latency
  12. Datastore Read Rate – Rate of reading data from the datastore. The value displayed belongs to the datastore with the highest read rate (needs to be explicitly enabled on XenServer)
  13. Datastore Write Rate – Rate of writing data to the datastore. The value displayed belongs to the datastore with the highest write rate (needs to be explicitly enabled on XenServer)
  14. Min Free Space on Datastore – Amount of free space available on the most occupied datastore
  15. NIC Usage – Sum of data transmitted and received across all physical NIC instances connected to the host

 

By default, the grid is sorted by CPU Usage in descending order.

The following additional functionality is offered by this report:

  • The folder selection dropdown allows for focusing the result of the report on a folder in your ControlUp organization. By default, data for the entire organization is shown.
  • The metrics dropdown allows to choose what metrics to display – average, minimum or maximum. By default, the average metrics are shown.
  • Any host name can be clicked to display the resource consumption trends of the selected host by linking to the Hosts Trends report
  • All columns can be sorted by clicking on the column header.
  • All columns can be filtered by clicking the filter icon in the column header.
  • The number of items displayed in the grid can be controlled by using the “items per page” dropdown at the bottom of the grid.
