Creating Performance Sessions Using a Script

The Sensor Management command line interface is called smcli. From the smcli command line, you can access another set of commands (called mgr-commands) that are used primarily to set up performance sessions.

To create performance sessions in bulk using a script, you prepare the script consisting of mgr-commands that create sender endpoints, reflector endpoints, and sessions. Then you execute the script in mgr-commands mode.

This article provides a procedure for loading and executing a script on the command line. It also provides an example script for creating performance sessions.

For detailed information about the smcli and mgr-commands, see the Sensor Management CLI Reference.

Procedure Requirements

1. Part of this procedure is performed in the Sensor Management console (smcli CLI).
2. Part of this procedure is performed in mgr-commands mode. To enter this mode, you must know the credentials for a valid Sensor Management user account (an account for the Sensor Management web interface).

You must prepare a script that includes all the commands needed to set up the session. For an example that you can use as a starting point, see Example Script for Creating Performance Sessions below.

Procedure Steps

During this procedure you will do the following tasks:

• Upload the script to the Sensor Management.
• Execute the script.

To upload the script to the Sensor Management

1. Use an SCP client (such as WinSCP) to transfer your script to the Sensor Management.

2. Copy your script to the sm-bizn pod.

To execute the script

1. Access smcli (see the Sensor Management CLI Reference.

2. At the prompt, enter this command to go into mgr-commands mode:

mgr-commands

3. At the mgr/mgr# prompt, enter this command to execute the script:

execute <the_path_to_your_script_in_the_core_container>/<your_script_file_name>

The commands in the script are displayed as they are executed.

4. When the script has run to completion, enter this command to confirm that any new reflectors and supervision endpoints were created:

show endpoint all

Confirm that new endpoints appear in the list.

5. Enter this command to check that new sessions were created:

show session

Confirm that new sessions appear in the list.

6. Exit mgr-commands mode by entering:

quit

Example Script for Creating Performance Sessions

This example script creates and configures four reflectors and sets up a TWAMP session.

The script consists of mgr-commands. For detailed descriptions of mgr-commands, see Sensor Management CLI Reference.
