One of the OpenProcurement toolkit components is Log server. Its aim is to provide trackability and meticulous auditing.
Log server ensures transparency of the Central database, web platforms, Auction module, other modules and system actors by collecting and storing system log files. Web platforms' logs that are generated during processing of their requests together with Central database logs provide complete tracking of the chain of events using ID correlation.
Logs are archived for auditing purposes.
Log delivery format:
- Online logs using syslog protocol, JSON.
- Logs in text and JSON formats periodically uploaded to Amazon S3.
Types of logs
- Public log - excludes the following types of information: that identifies the web platform that conducts transaction; and that can identify tender for which the price offer was posted in the system.
