METRON-2267: Audit Zookeeper config changes in REST

[merrimanr]

Contributor Comments

This PR adds logging for changes to Zookeeper configs (including user).

Testing

This has been tested in full dev.

1. Spin up full dev and change the Metron REST logging level to INFO as described here.

2. Navigate to Swagger and makes changes to parser, enrichment and indexing configurations (including delete). Log statements should reflect the changes made. For example, this request:

curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{
  "parserClassName": "org.apache.metron.parsers.bro.BasicBroParser",
  "filterClassName": null,
  "sensorTopic": "bro",
  "outputTopic": null,
  "errorTopic": null,
  "writerClassName": null,
  "errorWriterClassName": null,
  "readMetadata": false,
  "mergeMetadata": false,
  "numWorkers": null,
  "numAckers": null,
  "spoutParallelism": 1,
  "spoutNumTasks": 1,
  "parserParallelism": 1,
  "parserNumTasks": 1,
  "errorWriterParallelism": 1,
  "errorWriterNumTasks": 1,
  "spoutConfig": {},
  "securityProtocol": null,
  "stormConfig": {},
  "parserConfig": {
    "test": "value"
  },
  "fieldTransformations": [],
  "cacheConfig": {},
  "rawMessageStrategy": "DEFAULT",
  "rawMessageStrategyConfig": {}
}' 'http://user:password@node1:8082/api/v1/sensor/parser/config/bro'

Should cause this message to be logged in /var/log/metron/metron-rest.log:

2019-09-25 05:25:17.017  INFO 13505 --- [nio-8082-exec-1] o.a.m.r.c.SensorParserConfigController   : User 'user' changed the 'bro' parser config to org.apache.metron.common.configuration.SensorParserConfig@502e087f[parserClassName=org.apache.metron.parsers.bro.BasicBroParser,filterClassName=<null>,sensorTopic=bro,outputTopic=<null>,errorTopic=<null>,writerClassName=<null>,errorWriterClassName=<null>,readMetadata=false,mergeMetadata=false,numWorkers=<null>,numAckers=<null>,spoutParallelism=1,spoutNumTasks=1,parserParallelism=1,parserNumTasks=1,errorWriterParallelism=1,errorWriterNumTasks=1,spoutConfig={},securityProtocol=<null>,stormConfig={},cacheConfig={},parserConfig={test=value},fieldTransformations=[],rawMessageStrategy=DEFAULT,rawMessageStrategyConfig={}]
