Testing Assumptions


A single VES Collector will be pre-deployed for all flows

...

Assign values to the artifacts as in the below screenshot, and upload the provided blueprint.

Choose Deploy from Manage Menu

This may take on the order of tens of seconds, as it waits for DCAE to report final success.

Once the Deployment is successful in DCAE, Status will change to "Active"

The deploy window provides a JSON of inputs to provide to the deploy call:

  • The policyId field should be kept as-is
  • The rest of the JSON object should be replaced by the following.  external_port and scn_name need to be unique across existing deployments of TCA microservice

Run Control Loop Again

After the control loop is reconfigured, we test that the changes have taken effect.  This is done by running the control loop again.  For example, if the threshold value was increased, we would initiate an event with the old threshold value, and see that the signature is no longer produced.

Click on either the Policy box or the TCA box in order to bring up the details of the given policy

Update the values on the policy

Choose Update from the Manage CL Menu

Testing Directions


Choose Stop from the Manage Menu

The Status will change to "Stopped"

To verify, check Policy GUI to confirm that the BRMS policy under the control loop's scope has been removed


Choose Restart from the Manage Menu

The Status will change back to "Active"

To verify, check Policy GUI to confirm that the BRMS policy under the control loop's scope has been returned
