nickwallen commented on issue #1311: METRON-685 Scores in Threat Triage should be a Stellar Statement URL: https://github.com/apache/metron/pull/1311#issuecomment-452028532 @ottobackwards I addressed your feedback. Ran it up again and re-tested just to be sure. ``` [root@node1 0.7.0]# cat triage-test.stellar t := THREAT_TRIAGE_INIT() THREAT_TRIAGE_ADD(t, {"name":"rule1", "rule":"value>10", "score":10}) THREAT_TRIAGE_ADD(t, {"name":"rule2", "rule":"value>20", "score":"value*10"}) THREAT_TRIAGE_PRINT(t) msg1 := "{ \"value\":22 }" msg2 := "{ \"value\":44 }" THREAT_TRIAGE_SCORE( msg1, t) THREAT_TRIAGE_SCORE( msg2, t) ``` ``` [root@node1 0.7.0]# cat triage-test.stellar | bin/stellar SLF4J: Class path contains multiple SLF4J bindings.
