• Basic lua infrastructure
• How to extract the user that did the request from cookie JSESSIONID? Not possible, DHIS2 uses the standard in-memory HttpSession (for DB storage we need spring-session-jdbc + code)
• Implement filter what to log: "method==GET+url==/api/userGroups,method=GET+status!=2.."
• Integrate filter option in d2-docker start
• Use openresty as docker image
