METRON-739 Create Local Profile Runner Troubleshooting issues when programming against a live stream of data can be difficult. This is the primary reason that drove the creation of the REPL. Similarly it would be useful to have a means to run a profile locally to troubleshoot, validate, or debug a profile. Now you can, right in the REPL! Take it for a test spin. 1. Create your profiles. For this example, In the editor copy/paste in the basic "Hello, World" profile. ``` [Stellar]>>> conf := SHELL_EDIT() { "profiles": [ { "profile": "hello-world", "onlyif": "exists(ip_src_addr)", "foreach": "ip_src_addr", "init": { "count": "0" }, "update": { "count": "count + 1" }, "result": "count" } ] } ``` 1. Initialize the Profiler. ``` [Stellar]>>> profiler := PROFILER_INIT(conf) [Stellar]>>> profiler org.apache.metron.profiler.StandAloneProfiler@4f8ef473 ``` 1. Create some telemetry. In the editor, copy/paste in the message JSON. ``` [Stellar]>>> message := SHELL_EDIT() [Stellar]>>> message { "ip_src_addr": "10.0.0.1", "protocol": "HTTPS", "length": "10", "bytes_in": "234" } ``` 1. Apply some telemetry messages to your profiles. ``` [Stellar]>>> PROFILER_APPLY(message, profiler) org.apache.metron.profiler.StandAloneProfiler@4f8ef473 [Stellar]>>> PROFILER_APPLY(message, profiler) org.apache.metron.profiler.StandAloneProfiler@4f8ef473 [Stellar]>>> PROFILER_APPLY(message, profiler) org.apache.metron.profiler.StandAloneProfiler@4f8ef473 ``` 1. Flush the profiles, to see what it has calculated. The result is a list of profile measurements. Each value is a map containing detailed information about the profile measurements that were taken. ``` [Stellar]>>> values := PROFILER_FLUSH(profiler) [Stellar]>>> values := PROFILER_FLUSH(profiler) [Stellar]>>> values [{period={duration=900000, period=1669628, start=1502665200000, end=1502666100000}, profile=hello-world, groups=[], value=3, entity=10.0.0.1}] ``` I have added unit tests to cover all of the functionality, have tested the new Stellar functions in the REPL and have also completed a basic regression test for the Profiler itself. ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
