XenMobile Threads Test

How many requests a Endpoint Management can process depends upon the number of threads it has been configured with. Without adequate threads, the Endpoint Management server may not be able to service all requests, thus resulting in delays in request processing, long pending request queues, and degraded Endpoint Management performance. To avoid such anomalies, administrators will have to track the usage of threads by the Endpoint Management server, proactively detect a probable contention for threads, and accordingly decide whether/not to increase the size of the thread pool. To achieve this, administrators can take the help of the XenMobile Threads test. This test indisscates the maximum number of threads the Endpoint Management server can spawn, reports the percentage of threads currently in use, measures the length of the outstanding request queues on the XDM server, and thus reveals whether/not the Endpoint Management server needs to be configured with more threads to handle its current task load and to shorten the request queue. In addition, the test alerts administrators to any increase in the number of threads with errors.

Target of the test : A Citrix Endpoint Management

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the Endpoint Management MDM server 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 to be configured.
Port	The port at which the specified host listens. By default, this is 4443.
Login URL	This refers to the URL of the login page of the Endpoint Management Device Manager console. By default, eG Enterprise auto-discovers this URL. This is why, the Login URL is set to none by default.
Username and Password	Specify the credentials of a Endpoint Management user with Administrator privileges.
Confirm Password	Confirm the password by retyping it here.
SSL	Indicate whether/not the Endpoint Management server is SSL-enabled. By default, this flag is set to Yes

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Min threads	Indicates the minimum number of threads that should be available.	Number
Max threads	Indicates the maximum number of threads that the server can spawn.	Number
Pool increment	Indicates the number of threads by which the pool size has been increased since the last measurement period.	Number	A significant increase in the value of this measure is indicative of an increase in the load on Endpoint Management.
Current threads	Indicates the number of threads currently active.	Number	This is a good indicator of the current load on Endpoint Management.
Waiting threads	Indicates the number of threads that are waiting currently.	Number
Active Threads	Indicates the number of threads that are currently active.	Number
Percentage of active threads	Indicates the percentage of threads that are currently active.	Percent	If the value of this measure is close to 100%, it could indicate that Endpoint Management is about to utilize its entire thread pool. Under such circumstances, you can consider increasing the maximum number of threads that your Endpoint Management can spawn.
Task count	Indicates the number of tasks currently running on the server.	Number
Queue length	Indicates the current length of the request queue.	Number
Working queue length	Indicates the current length of the working queue.	Number
Total queue size	Indicates the total number of items in queue since the last measurement period.	Number	A consistent increase in the value of this measure could indicate a processing bottleneck on the Endpoint Management server. Check the value of the Percentage of active threads measure for the server to determine whether the lack of sufficient threads in the Endpoint Management’s thread pool is the reason for the bottleneck. If so, you may want to increase the ‘maximum threads’ setting for the Endpoint Management server.
Ran count	Indicates the number of threads that ran during the last measurement period.	Number
Errors	Indicates the number of threads with errors during the last measurement period.	Number	Ideally, the value of this measure should be 0 at all times.
Cancels	Indicates the number of threads that were canceled during the last measurement period.	Number
Packets	Indicates the number of packets processed during the last measurement period.	Number
