vCD User Sessions Test

User sessions serve as good indicators of the workload of a vCloud Director cell. Using this test, you can not only understand the session load on the vCloud Director cell, but can also rapidly determine if any login attempt to the vCloud Director cell 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
Total sessions	Indicates the total number of sessions to the vCloud Director cell.	Number	This is a good indicator of how busy the vCloud Director cell is.
Successful logins	Indicates the number of login attempts to the vCloud Director cell that were successful.	Number
Failed logins	Indicates the number of login attempts that failed.	Number	Ideally, the value of this measure should be 0.
