The Platform Maturity requirements for Beijing are on this page:
Platform Maturity Requirements (aka Carrier Grade)
The ambition for the ONPA Policy Framework is to reach level 1 in performance in Beijing, see JIRA POLICY-392
For Performance Level 1, we have to define and measure our performance metrics:
Level 1: baseline performance criteria identified and measured (such as response time, transaction/message rate, latency, footprint, etc. to be defined on per component
I don't think we have to state what the metrics should be, it looks like we just define the metrics and measure them. For Level 2, an improvement plan must be created and implemented.
Although there should be measurements for design time and deployment time performance, here we focus on the run time performance metrics for policy execution in the PDPs, the most critical run time metrics for Policy. We propose to measure these metrics in a simulated environment and in a full ONAP deployment.
Measurements for the "Single Threaded" case are made using the Stability test, which uses timers to determine when to inject responses via REST. It also uses the REST API to look for "FINAL" states, thus it is limited to two threads. On the other hand, the measurements for the "Multi Threaded" case are made using the Performance test, which uses DMaaP notifications to determine when to inject responses via REST. It also uses DMaaP notifications to look for "FINAL" states, thus it is only limited by how many simultaneous consumers and connections are supported by DMaaP.
| No. | Metric | Description |
|---|---|---|
| 1 | Single Threaded Response Time | Measure the execution time for onset and abatement in each use case with only a single policy executing |
| 2 | Single Threaded CPU Usage | CPU Usage for each use case when executing alone |
| 3 | Single Threaded Memory Usage | Memory Usage for each use case when executing alone |
| 4 | Maximum Simultaneous Executions | Measure the maximum number of simultaneous policy executions that can be achieved whilst maintaining system stability and resource utilization |
| 5 | Multi Threaded Response Time | Measure the execution time for onset and abatement in each use case when multiple threads are injecting ONSET events simultaneously |
| 6 | Multi Threaded CPU Usage | CPU Usage for each use case when multiple threads are injecting ONSET events simultaneously |
| 7 | Multi Threaded Memory Usage | Memory Usage for each use case when executing in multiple threads |
| 8 | Installation Footprint | The requirements of the ONAP Policy Framework installation in terms of VM resources including the amount of disk space required for the database and for logs. |
