NCMP De-registration Performance test guide

Manual testing with Postman

1. Build cps-and-ncmp docker image for version to be tested. Run maven from cps repo directory:

   mvn clean install -Pcps-ncmp-docker

2. Edit docker-compose.yml to filter notifications: set NOTIFICATION_DATASPACE_FILTER_PATTERNS to NON-EXISTING-DATASPACE

   cps-and-ncmp:
     environment:
       notification.enabled: 'true'
       NOTIFICATION_DATASPACE_FILTER_PATTERNS: 'NON-EXISTING-DATASPACE'

3. Start docker-compose with DMI plugin stub and monitoring enabled:

   docker-compose -f docker-compose/docker-compose.yml --profile dmi-stub --profile monitoring up

4. Wait for CPS to start. Console output will show:

   cps-and-ncmp            | {"logTimeStamp":"2023-03-24T16:20:36.705Z","logLevel":"INFO","principalId":"cpsuser","serviceName":"cps-application","message":"Started Application in 47.336 seconds (JVM running for 48.444)","processId":"1","threadName":"main","class":"org.onap.cps.Application"}

5. Test using Postman
   1. Start Postman, and import the NCMP de-register performance postman collection
      
   2. Click the new collection, and open the "Variables" tab
      
   3. Change the current value of TOTAL_CMHANDLES to the desired value, e.g. 10000, and click the "Save" button.
      
   4. Select "Register CM handles", and click "Send". (The Postman collection will use a script to automatically create the request body.)
      
   5. Wait until all CM handles are in READY state.
      This will be done by running a query on the database. Here are instructions using the postgresql command line interface, but you may alternatively use the Postgres GUI client.
      1. Open a new terminal window

      2. Run psql command to connect to the database (default password is cps):

         psql -h localhost -p 5432 cpsdb cps
         Password for user cps: 
         psql (14.6 (Ubuntu 14.6-0ubuntu0.22.04.1), server 14.1)
         Type "help" for help.
         
         cpsdb=# 

      3. Run the following query to count the number of handles in the READY state. You will need to repeat this command, until all are ready (e.g. 10000).

         cpsdb=# SELECT count(*) FROM public.fragment where attributes @> '{"cm-handle-state": "READY"}';
          count 
         -------
           2384
         (1 row)
         
         cpsdb=# SELECT count(*) FROM public.fragment where attributes @> '{"cm-handle-state": "READY"}';
          count 
         -------
          10000
         (1 row)

      4. Now that all CM handles are ready, we can proceed to test de-registration. Go back to Postman.
   6. Select "De-Register CM handles", and click "Send"
   7. Record the time taken

6. Stop docker-compose:

   docker-compose -f docker-compose/docker-compose.yml down

7. Clean up docker containers and volumes:

   docker container prune -f && docker volume prune -f
