[jira] [Updated] (METRON-685) Scores in Threat Triage should be a Stellar Statement

     [ https://issues.apache.org/jira/browse/METRON-685?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Simon Elliston Ball updated METRON-685:
---------------------------------------
    Description: 
When writing threat triage rules I would like the score for a rule to be determined by a stellar statement, rather than a fixed number triggered by a boolean stellar statement.

For example: 
{code}
"triageConfig" : {
 "riskLevelRules" : [
   {
     "name" : "Abnormal Value",
     "comment" : "FORMAT('For %s; the value %s exceeds threshold of %d',
hostname, value, value_threshold)"
     "rule" : "SOME_STELLAR_FUNCTION(value) > value_threshold",
     "score" : "SOME_STELLAR_FUNCTION(value)"
   }
 ],
 "aggregator" : "MAX"
}
{code}

Note that in this scenario it would also be beneficial to cache part of the statement to avoid likely duplication between rule and score evaluation.
