Parameter description

**Table 2** Parameters in the request
Parameter	Mandatory	Type	Description
service_type	No	String	Type of a service whose traces are to be queried. The value must be the acronym of a cloud service that has been connected with CTS. It is a word composed of uppercase letters. For cloud services that can be connected with CTS, see section "Supported Services and Operations" in the Cloud Trace Service User Guide.
resource_type	No	String	Type of a resource whose traces are to be queried. The value can contain 1 to 64 characters, including letters, digits, hyphens (-), underscores (_), and periods (.). It must start with a letter. For cloud services that can be connected with CTS, see section "Supported Services and Operations" in the Cloud Trace Service User Guide.
resource_id	No	String	ID of a cloud resource whose traces are to be queried.
resource_name	No	String	Name of a resource whose traces are to be queried. NOTE: The resource name is case sensitive.
trace_name	No	String	Trace name. It indicates the operation recorded by this trace. NOTE: The trace name is case sensitive.
limit	No	String	Number of traces returned in the trace list. The default value is 50 and the maximum value is 200.
next	No	String	This parameter is used to query traces generated earlier than its specified value. The value can be that of marker in Table 5. next can be used with from and to. Traces generated in the overlap of the two time ranges specified respectively by next and by from and to will be returned.
from	No	String	UTC timestamp of the start time of the query time range. The value is in milliseconds and contains 13 digits. Traces generated on the specified timestamp are not returned. The parameters from and to should be used together.
to	No	String	UTC timestamp of the end time of the query time range. The value is in milliseconds and contains 13 digits. Traces generated on the specified timestamp are not returned. The parameters to and from should be used together.
trace_id	No	String	Trace ID. If this parameter is specified, other query criteria will not take effect.
trace_status	No	String	Status of a trace. The value can be normal, warning, or incident.
user	No	String	Name of the user whose traces are to be queried. NOTE: The username is case sensitive.
