auditor-spring

Spring boot application used to audit (trace) user requests.

Solves persistent tracing requirement in microservice architecture. Tracing service should run in separate machine (This is even more important if file audit is chosen). Backing up data saved by auditor is also recommended.

All audit info is saved to permanent location which is configurable via spring profiles. Currently two options are supported:

  • db-audit - saves data to any db

  • file-audit - saves data locally

  • Listener for JMS queue reads data and stores it to database/file - this option is configurable via spring profiles (db-audit, file-audit)

  • Direct saving to permanent storage location

STREAM SUPPORT

Supports handling (reading) audit info from external broker (e.g. Rabbit MQ or Kafka, depending on the implementation you choose)

  • Implemented using Spring Cloud Stream
  • turned off by default. To enable it add stream-on as one of active spring profiles

REST API

Two API edpoints are available:

  • /audit/mq - Receives single audit info that is pushed into JMS (later processed and saved to permanent location)
  • /audit/direct - Receives multiple audit info elements and saves them directly to permanent location (this can either be file or database)

Recover option

In case of failed saving (after certain number of attempts). Failed requests are logged locally and retried again on scheduled bases

Database auditing

File auditing

Auto schema generation

Auditor uses only one table (audit_info) that is automatically created if it does not yet exist
