Explanation

Cloud Audit Service (CTS) is designed for security compliance and governance - it records user operations and API calls to provide an audit trail for accountability purposes. It does not perform real-time monitoring, alarm association, log analysis, or distributed call tracking, so it sits outside Huawei's three-dimensional O&M framework. AOM (Application Operations Management) is a core O&M service that monitors applications and infrastructure resources, handles alarms, and enables centralized operational management. APM (Application Performance Management) directly supports the O&M goal of rapid problem diagnosis by tracking application performance, response times, and distributed call chains. DBSS (Database Security Service) is included in the O&M solution scope because it provides real-time monitoring and security analysis of database activity, fitting the multi-dimensional monitoring requirement.

Memory tip: CTS records history for auditors and compliance teams - think of it as a logbook, not a dashboard. Anything that monitors live systems and triggers alarms belongs to O&M; anything that passively records past events for governance belongs to audit.
