| Enable Audit Collection | Enable collection of audit events from the service's roles. | true | navigator_audit_enabled | false | |
| Audit Event Filter | Event filters are defined in a JSON object like the following: { "defaultAction" : ("accept", "discard"),
"rules" : [ { "action" : ("accept", "discard"), "fields" : [ { "name" : "fieldName", "match" : "regex" } ] } ] } A filter has a default action and a list of rules, in order of precedence. Each
rule defines an action, and a list of fields to match against the audit event. A rule is "accepted" if all the listed field entries match the audit event. At that point, the action declared by the
rule is taken. If no rules match the event, the default action is taken. Actions default to "accept" if not defined in the JSON object. The following is the list of fields that can be filtered for
Hive events:
|
navigator.event.filter | comment: [ The default Hive audit event filter discards HDFS directory events , generated by Hive jobs that reference the /tmp directory. ], defaultAction: accept, rules: [ action: discard, fields: [ name: operation, match: QUERY , name: objectType, match: DFS_DIR , name: resourcePath, match: /tmp/hive-(?:.+)?/hive_(?:.+)?/-mr-.* ] ] | navigator_audit_event_filter | false |
| Audit Queue Policy | Action to take when the audit event queue is full. Drop the event or shutdown the affected process. | navigator.batch.queue_policy | DROP | navigator_audit_queue_policy | false |
| Audit Event Tracker | Configures the rules for event tracking and coalescing. This feature is used to define equivalency between different audit events.
When events match, according to a set of configurable parameters, only one entry in the audit list is generated for all the matching events. Tracking works by keeping a reference to events when they
first appear, and comparing other incoming events against the "tracked" events according to the rules defined here. Event trackers are defined in a JSON object like the following: { "timeToLive" : [integer], "fields" : [ { "type" : [string], "name" : [string] } ] } Where:
