Our solution aims to create a single audit trail for health institutions that collects different logs (ex: syslog, log4j, HL7, web servers logs). This solution is aligned with the IHE-ATNA (Audit Trail and Node Authentication) profile. It allows to perform audit processes that cross different systems in an integrated manner, as well as to diagnose problem occuring in different systems using a single dashboard.
