Real-time Monitoring Service (RMS) allows you to query traces based on multi-dimension search criteria. You can query traces of different types of requests, such as HTTP, RPC, DB, MQ, and CACHE requests. You can also query traces by specifying a custom scenario tag, such as transaction number. This topic describes how to query traces in the RMS console.
