vCenter Object Validations Test

For every validator configured on the vCloud Director cell, this test reports the total number of vCenter (VC) object executions that are available for validation, and thus indicates the load per validator. Also, by reporting the length of the validation queue and the count of objects requeued, the test brings probable processing bottlenecks in the validator to the attention of administrators.

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 each validator configured on 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
Total invocations	Indicates the total number of VC object executions that are available for validation on this validator.	Number	A high value is indicative of a heavy load on a validator. Compare the value of this measure across validators to know which validator is handling the maximum load. For the global descriptor, this measure reports the total number of VC object executions that are available for validation across all validators.
Objects in queue	Indicates the total number of items (VC objects) that were currently queued for validation.	Number	This measure is not applicable for the global descriptor.
Object busy requeue count	Indicates the number of VC objects that were requeued for validation.	Number	The objects are requeued only when the objects were busy during validation.
Duplicate discarded	Indicates the total number of duplicate VC objects that were discarded during validation.	Number
