Function¶

This API is used to create structuring configurations using a structuring template, which facilitates parameter extraction and simplifies the parameter structure.

A user can call this API only once per second.

URI¶

POST /v3/{project_id}/lts/struct/template

**Table 1** Path Parameters¶
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain a project ID, see Obtaining the Project ID, Account ID, Log Group ID, and Log Stream ID. Minimum: 32 Maximum: 32

Request Parameters¶

**Table 2** Request header parameters¶
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token obtained from IAM. For details about how to obtain a user token, see Obtaining a User Token. Minimum: 1000 Maximum: 2000
Content-Type	Yes	String	Set this parameter to application/json;charset=UTF-8. Minimum: 30 Maximum: 30

**Table 3** Request body parameters¶
Parameter	Mandatory	Type	Description
log_group_id	Yes	String	Log group ID. For details about how to obtain a log group ID, see Obtaining the Project ID, Account ID, Log Group ID, and Log Stream ID. Minimum: 36 Maximum: 36
log_stream_id	Yes	String	Log stream ID. For details about how to obtain a log stream ID, see Obtaining the Project ID, Account ID, Log Group ID, and Log Stream ID. Minimum: 36 Maximum: 36
template_id	Yes	String	Template ID. When the system template is used, the current attribute can be empty. Minimum: 0 Maximum: 36
template_name	Yes	String	Template name, which cannot be empty and will be verified. Minimum: 1 Maximum: 64
template_type	Yes	String	Type of the template. The value can be built_in (system templates) or custom (custom templates). For details about system template types, see section "Log Search and Analysis" > "Cloud Structuring Parsing" > "Structuring Templates" in the LTS User Guide.
demo_fields	No	Array of FieldModel objects	Example field array. You only need to enter the fields whose status is different from that of is_analysis in the template.
tag_fields	No	Array of FieldModel objects	Tag field array. You only need to enter the fields whose status is different from that of is_analysis in the template.
quick_analysis	No	Boolean	Indicates whether to enable quick analysis for demo_fields and tag_fields. If this parameter is set to true, quick analysis is enabled for all fields. If this parameter is left blank or set to false, is_analysis in the template is used to determine whether to enable quick analysis.

**Table 4** FieldModel¶
Parameter	Mandatory	Type	Description
field_name	Yes	String	Field name. A log event can be split into multiple fields with customizable names. Minimum: 1 Maximum: 64
is_analysis	No	Boolean	Whether quick analysis is enabled.
