Measures reported by vCldEsxHostsStTest

For each vSphere host that is managed by the vCenter server attached to the vCloud Director Cell being monitored, this test reports the following:

  • Whether/not the host is available;
  • Whether the host is disabled/enabled;
  • Whether the host is ready or not;
  • Whether ‘Host Spanning’ is enabled on the host or not;

In addition, the test also indicates the CPU/memory capacity and usage of each host, so that you can make a fair assessment of the amount of resources that is available to the vCloud Director Cell for pooling. The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Available Indicates whether/not this vSphere host is currently available on the vCenter server.   This measure reports a value Yes if the vSphere host is available and a value No if the vSphere host is not available.

The numeric values for the above mentoioned states are represented in the table below:

State Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the above-mentioned States while indicating whether/not this vSphere host is available. However, in the graph of this measure, states will be represented using their corresponding numeric equivalents only.

Busy Indicates whether/not this vSphere host is currently busy.   This measure reports a value Yes if the vSphere host is currently busy and a value No if the vSphere host is free.

The numeric values for the above mentoioned states are represented in the table below:

State Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the above-mentioned States while indicating whether/not this vSphere host is busy. However, in the graph of this measure, states will be represented using their corresponding numeric equivalents only.

Enabled Indicates whether/not this vSphere host is enabled.   You can disable a host to prevent vApps from starting up on the host. Virtual machines that are already running on the host are not affected.

This measure reports a value Yes if this vSphere host is currently enabled and a value No if this vSphere host is disabled.

The numeric values for the above mentoioned states are represented in the table below:

State Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the above-mentioned States while indicating whether/not the vSphere host is enabled. However, in the graph of this measure, states will be represented using their corresponding numeric equivalents only.

EnableHostForSpanning Indicates whether/not host spanning is currently enabled on this vSphere host.   Host Spanning is a feature that enables the virtual machines in a configuration that uses fencing or virtual networks to be deployed on different ESX/ESXi hosts. When you deploy a configuration that uses Host Spanning, some of the virtual machines can get deployed to one ESX/ESXi host and some of the virtual machines can get deployed to a different host.

This measure reports a value Yes if host spanning is enabled on the vSphere host and a value No if host spanning is not enabled. If the measure reports the value Yes, then it indicates that the vSphere host cannot be put in standby or maintenance modes.

The numeric values for the above mentoioned states are represented in the table below:

State Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the above-mentioned States while indicating whether/not host spanning is enabled/disabled. However, in the graph of this measure, states will be represented using their corresponding numeric equivalents only.

Ready Indicates whether/not this vSphere host is currently ready.   This measure reports a value Yes if the vSphere host is currently ready and a value No if the vSphere host is not ready.

The numeric values for the above mentoioned states are represented in the table below:

State Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the above-mentioned States while indicating whether/not the vSphere host is ready. However, in the graph of this measure, states will be represented using their corresponding numeric equivalents only.

Host_total_cpu Indicates the total CPU capacity of this host. Mhz  
Host_cpu_cycles Indicates the number of CPU cycles consumed by all processes that were executing on this host during the last measurement period. Number A high value is indicative of excessive CPU usage.
Host_cpu_packages Indicates the number of CPU packages present in this vSphere host. Number  
Host_total_memory Indicates the total memory capacity of this vSphere host. MB  
Host_memory_used Indicates the amount of memory that is currently utilized by this vSphere host. MB A sudden or steady increase in the value of this measure is indicative of excessive memory usage by the host.
