vCD Presentation Querys Test

Using the vCloud API query service, administrators can build typed and packaged queries that can be executed on the vCloud Director database for retrieving information about objects in the cloud. The vCD Presentation Querys test enables administrators to track the status of every query built and executed via the query service, so that query failures can be instantly detected.

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 query executed by the query service of 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
Current invocations	Indicates the number of invocations that are currently active for this query.	Number
Failed executions	Indicates the number of executions that failed for this query.	Number	Ideally, the value of this measure should be 0.
Total invocations	Indicates the total number of invocations for this query.	Number
