Log Server


  1. To ensure transparency of the Central DB, platforms, Auction module, Administrator, other modules and system actors by publishing system log files.
  2. To enable self-service of platforms that are already connected or will be connected to the system by tracking logs that are generated during processing of their requests until the integration of Central DB logs with platforms’ log servers while providing complete tracking of the chain of events using ID correlation.
  3. To archive logs for auditing purposes.
