Basic Concepts

Trackers

When you enable CTS for the first time, a management tracker named system is created automatically.

Th management tracker identifies and associates with all cloud services your tenant account is using, and records all operations of your tenant account.

Currently, only one tracker can be created for each tenant.

Traces

Traces are operation logs of cloud service resources and are captured and stored by CTS. You can view traces to get to know details of operations performed on specific resources.

Traces: management traces reported by cloud services.

Trace List

The trace list displays traces generated in the last seven days. These traces record operations (in the last hour by default) on cloud service resources, including creation, modification, and deletion, but do not record query operations.

• Management traces: record details about creating, configuring, and deleting cloud service resources in your tenant account.

Trace Files

A trace file is a collection of traces. CTS generates trace files based on services and transfer cycle and send these files to your specified OBS bucket in real time. In most cases, all traces of a service generated in a transfer cycle are compressed into one trace file. However, if there are a large number of traces, CTS will adjust the number of traces contained in each trace file.

Traces files are in JSON format. Figure 1 shows an example of a trace file.

Regions

A region refers to a geographic area where the server for installing CTS is located. AZs in the same geographic area can communicate with each other through an internal network.

Data centers (DCs) of the cloud platform are scattered across different regions of the world, for example, Europe and Asia. Enabling CTS in different regions makes applications more user-friendly and meets the laws and regulations of different regions.

Projects

A project corresponds to a cloud platform region. Default projects are defined to isolate resources (including computing, storage, and network resources) across regions. You can create sub-projects in a default region project to isolate resources more precisely.
