VCD vCenter Tasks Test

This test reports the Virtual Center Task Manager statistics. Using this test, you can easily figure out the following:

  • The number of VC tasks that were successful and that failed during the last measurement period
  • The number of times the wait for task inventory event was invoked
  • The number of task completions that were received
  • The number of task completion messages that were received and were published on the message bus and
  • The time duration that elapsed for a task to be completed successfully and for a task that failed

Target of the test : A vCloud Director Cell

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the vCloud Director Cell being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The host for which the test is being configured.

Port

Specify the port at which the specified host listens in the Port text box. By default, this is NULL.

JMX Remote Port

Here, specify the port at which the JMX listens for requests from remote hosts. Ensure that you specify the same port that you configured in the vmware-vcd-cell file in the /opt/vmware/vcloud-director/binfolder of the vCloud Director.

JNDIName

The JNDIName is a lookup name for connecting to the JMX connector. By default, this is jmxrmi. If you have registered the JMX connector in the RMI registry using a different lookup name, then you can change this default value to reflect the same.

User, Password, and Confirm Password

By default, JMX requires no authentication or security (SSL). This is why, by default, the User and Password parameters are set to none. If JMX requires authentication only (but no security), then ensure that the User and Password parameters are configured with the credentials of a user with read-write access to JMX. To know how to create this user, refer to Pre-requisites for Monitoring vCloud Director. Confirm the password by retyping it in the Confirm Password text box.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Successful tasks

Indicates the total number of VC tasks that were successful during the last measurement period.

Number

A high value is desired for this measure.

Failed tasks

Indicates the total number of VC tasks that failed during the last measurement period.

Number

Ideally, the value of this measure should be zero.

Wait for task invocation

Indicates the number of times the wait for task VIM Inventory event was invoked during the last measurement period.

Number

A Wait for Task event is triggered when a task is configured to wait for another long-running process/task to complete before it starts. For instance, a task can be configured to wait on a vCO/vCenter workflow to complete and then to resume, abort gracefully or fail the task before it has a chance to start.

Completed task waits

Indicates the total number of wait for task VIM Inventory events that were completed during the last measurement period.

Number

Historical tasks updates received

Indicates the total historical task updates received during the last measurement period.

Number

 

Tasks completion received

Indicates the number of task completions that were received during the last measurement period.

Number

 

Task completion msg published on msg bus

Indicates the number of task completion messages that were published on the message bus during the last measurement period.

Number

 

Task completion msg received on msg bus

Indicates the number of task completion messages that were received on the message bus during the last measurement period.

Number

 

Time elapsed for successful tasks

Indicates the time duration that elapsed for the tasks to be completed successfully during the last measurement period.

Secs

 

Time elapsed for failed tasks

Indicates the time duration that elapsed for the tasks that failed during the last measurement period.
