DNS Operations Recorded by CTS

CTS records DNS operations performed by users in real time. Actions and results of the operations are stored in OBS buckets in the form of traces.

After you enable CTS, whenever a DNS API is called, the operation is recorded in a log file, which is then delivered to a specified OBS bucket for storage.

Table 1 and Table 2 list the DNS operations that will be recorded by CTS.

The DNS service involves resources both at the global and region levels. Table 1 lists DNS operations at the global level. Traces of these operations are displayed only in the primary region.

Table 2 lists DNS operations at the region level. Traces of these operations are displayed in the regions where the operations are performed.
