Response Parameters

Status code: 200

**Table 3** Response body parameters
Parameter	Type	Description
trackers	Array of TrackerResponseBody objects	List of tracker information.

**Table 4** TrackerResponseBody
Parameter	Type	Description
id	String	Unique tracker ID.
create_time	Long	Timestamp when the tracker was created.
kms_id	String	Key ID used for transferring and encrypting trace files. This key ID is obtained from Key Management Service (KMS). This parameter is mandatory when tracker_type is set to system and is_support_trace_files_encryption is set to true.
is_support_validate	Boolean	Whether to enable trace file verification.
lts	Lts object	Detail about trace analysis.
tracker_type	String	Tracker type. The value can be system (management tracker), or data (data tracker). Enumerated values: system data
domain_id	String	Account ID. For details, see section "Obtaining an Account ID and Project ID" in Cloud Trace Service API Reference.
project_id	String	Project ID.
tracker_name	String	Tracker name. The default value is system.
status	String	Tracker status. The value can be enabled, disabled, or error. If the value is set to error, the detail field is required for specifying the source of the error. Enumerated values: enabled disabled
detail	String	This parameter is returned only when the tracker status is error. It indicates the cause of the abnormal status, and its value can be bucketPolicyError, noBucket, or arrears.
is_support_trace_files_encryption	Boolean	Whether trace files are encrypted during transfer to an OBS bucket. This parameter must be used with kms_id. This function is supported only when the value of tracker_type is system.

data_bucket	DataBucketQuery object	Information about the bucket tracked by a data tracker. This parameter is valid when tracker_type is set to data.
group_id	String	LTS log group ID.
stream_id	String	LTS log stream ID.
is_organization_tracker	Boolean	Whether to apply the tracker configuration to the organization. This parameter is valid only for the management tracker. If the value is set to true, the audit logs of all members in the ORG organization in the current region will be transferred to the OBS bucket or LTS log stream configured for the management tracker. However, audit logs of other members cannot be viewed on the Trace List page.
management_event_selector	ManagementEventSelector object	Management trace selector.
agency_name	String	Name of a cloud service agency.

file_prefix_name	String	Prefix of trace files that need to be stored in OBS buckets. The value can contain 0 to 64 characters, including letters, digits, hyphens (-), underscores (_), and periods (.).
is_obs_created	Boolean	Whether the OBS bucket is automatically created by the tracker.
is_authorized_bucket	Boolean	Whether CTS has been granted permissions to perform operations on the OBS bucket.
bucket_lifecycle	Long	Duration that traces are stored in the OBS bucket. This parameter is valid when tracker_type is set to data.
compress_type	String	Compression type. The value can be JSON (no compression) or GZIP (compression). The default format is GZIP. Enumerated values: gzip json
is_sort_by_service	Boolean	Whether to sort the path by cloud service. If this option is enabled, the cloud service name is added to the transfer file path. The default value is true.

search_enabled	Boolean	Whether the logs of the tracked bucket can be searched.
data_event	Array of strings	Name of the bucket tracked by a data tracker. This parameter is mandatory when the data tracker is enabled or disabled. This parameter is unavailable for a management tracker. Once a tracker is created, the bucket that it tracks cannot be changed. READ OBS: read operations; WRITE OBS: write operations.
