Set the Symping tool to return useful information on workload cycle (default) or task overhead.
Complete workload cycle is optimized to run workload through the cluster with full recoverability enabled (session and history). It provides minimum, maximum, and average roundtrip times. The average processing time (averaged across all hosts) also displays.
Task overhead is optimized to calculate task overhead—the delay involved in processing work. Results include overhead for longest and shortest task, average overhead, and average processing time.

Session tag
|
Adds a session tag to any session created by Symping. A session tag that is shared among sessions provides the ability to query or control these related sessions with a single action.
|
Task tag
|
Adds a task tag to all Symping tasks. The task tag can later be used to filter only those tasks that share the given tag.
|
Application name
|
The name of the application that Symping submits the workload to. If you want to use Symping to submit workload to another application, you need to first register that application with Symphony. If you have a mixed cluster, refer to your installation guide to ensure you have made the necessary modifications for Symping to run.
Important: As a best practice, name any applications using the Symping client with "symping" for easy identification. If you copy and rename this application, keep "symping" in the file name so that you can distinguish the applications related to the Symping client from those that are not.
|
Session type
|
Specifies the type of the session (for example, recoverable with task and session history enabled). Enabling history and recoverability increases the task and session overhead but more likely simulates a production environment. RecoverableAllHistoricalData: Session is recoverable and task and session history are set to "All". This is the default session type when you choose to run Symping configured for workload submission.
RecoverableNoHistoricalData: Session is recoverable but no history (session or task) is kept.
UnrecoverableAllHistoricalData: Session is unrecoverable and task and session history are set to "All".
UnrecoverableNoHistoricalData: Session is unrecoverable and no history (task or session) is kept. This is the default session type if you choose to run Symping configured for task overhead.
|
Common data size
|
Specifies the size of the common data that is associated with the session and passed from the client to the service, in bytes by default.
|
Input message size
|
Specifies the size of all input messages for each task in the session, in bytes by default.
|
Output message size
|
Specifies the size of all output messages for each task in the session, in bytes by default.
|
Task processing time
|
Duration of the task processing time.
|
# of tasks
|
Specifies the number of tasks that are sent during the testing. If you do not specify the number of tasks, the client application creates one session with 20 tasks.
|
Consume CPU cycles
|
Select if the tasks should consume CPU cycles when running. Option only displays when testing for complete workload cycle.
|
Log option
|
Generates a service log file on compute hosts on which the symping service runs.
The log is written to:
The log file is named according to session and task IDs: sessionID.taskID.
Without this option, no service log is generated.
|
Compress data
|
Specifies that all task inputs and outputs, as well as common data should be compressed.
