    456457Enabling the OWAMP and BWCTL daemons is all we need to perform on-demand active measurements. However, it's usually better to have active measurements running regularly to analyze the performance over time. Throughput and ping tests can be scheduled with a given interval (e.g. every 30 minutes). One-way delay tests are scheduled as a stream (a constant amount of packets is sent per second).

    484485
    485486pSConfig will pull the node's configuration from UNIS every 30 minutes (from the time it was started, not hh:00 and hh:30). Since we don't want to wait this long to start gathering data, we can restart pSConfig on each node by clicking the Apply Config link. This is achieved by ssh'ing to the node and restarting pSConfig, so errors are usually ssh related.
     
    489490Make sure you apply the configuration on all three nodes. We will now run the user experiment to generate some heavier traffic on the slice before looking at the data.

    494 3.2)  Configure selected experiment services
    495 
    496  - objectives:
    497    - binds services together to realize overall reference/actual experiment
    498    - configures baseline services
    499    - verifies that they are ready to run   
    500    
    501  - at completion:    configured experiment services, ready to run and process data, which can be observed by I&M services
