CreateLogStore - Log Service - Alibaba Cloud Documentation Center

Creates a Logstore.

Usage notes

Host consists of a project name and a Simple Log Service endpoint. You must specify a project in Host.
An AccessKey pair is created and obtained. For more information, see AccessKey pair.
The AccessKey pair of an Alibaba Cloud account has permissions on all API operations. Using these credentials to perform operations in Simple Log Service is a high-risk operation. We recommend that you use a RAM user to call API operations or perform routine O&M. To create a RAM user, log on to the RAM console. Make sure that the RAM user has the management permissions on Simple Log Service resources. For more information, see Create a RAM user and authorize the RAM user to access Simple Log Service.
The information that is required to query logs is obtained. The information includes the name of the project to which the logs belong and the region of the project For more information, see Manage a project.
You can create up to 200 Logstores in a project.
If the retention period of a log reaches the data retention period that you specified for the Logstore, the log is deleted.

Authentication resources

The following table describes the authorization information that is required for this operation. You can add the information to the Action element of a RAM policy statement to grant a RAM user or a RAM role the permissions to call this operation.

Action	Resource
`log:CreateLogStore`	`acs:log:{#regionId}:{#accountId}:project/{#ProjectName}/logstore/{#LogstoreName}`

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request headers

This operation uses only common request headers. For more information, see Common request headers.

Request syntax

POST /logstores HTTP/1.1

Request parameters

Parameter	Type	Position	Required	Example	Description
project	String	Host	Yes	ali-test-project	The name of the project.
	Object	Body	Yes		The request body.
logstoreName	String	Body	Yes	my-logstore	The name of the Logstore. The name must meet the following requirements: The name must be unique in a project. The name can contain only lowercase letters, digits, hyphens (-), and underscores (_). The name must start and end with a lowercase letter or a digit. The name must be 3 to 63 characters in length.
shardCount	Integer	Body	Yes	2	The number of shards. Note You cannot call the CreateLogStore operation to change the number of shards. You can call the SplitShard or MergeShards operation to change the number of shards.
ttl	Integer	Body	Yes	1	The retention period of data. Unit: days. Valid values: 1 to 3000. If you set this parameter to 3650, data is permanently stored.
encrypt_conf	EncryptConf	Body	No		The data structure of the encryption configuration.
autoSplit	Boolean	Body	No	true	Specifies whether to enable automatic sharding. Valid values: true false
enable_tracking	Boolean	Body	No	false	Specifies whether to enable the web tracking feature. Default value: false. Valid values: true false
maxSplitShard	Integer	Body	No	64	The maximum number of shards into which existing shards can be automatically split. Valid values: 1 to 256. Note If you set autoSplit to true, you must specify maxSplitShard.
appendMeta	Boolean	Body	No	false	Specifies whether to record public IP addresses. Default value: false. Valid values: true false
telemetryType	String	Body	No	None	The type of the observable data. Valid values: None (default): logs Metrics: metric
hot_ttl	Integer	Body	No	60	The retention period of data in the hot storage tier of the Logstore. Valid values: 7 to 3000. Unit: days. Hot data that is stored for longer than the period specified by hot_ttl is converted to the Infrequent Access (IA) storage tier. For more information, see Enable the hot and cold-tiered storage feature.
mode	String	Body	No	standard	The type of the Logstore. Simple Log Service provides two types of Logstores: Standard Logstores and Query Logstores. standard: Standard Logstore. This type of Logstore supports the log analysis feature and is suitable for scenarios such as real-time monitoring and interactive analysis. You can also use this type of Logstore to build a comprehensive observability system. query: Query Logstore. This type of Logstore supports high-performance queries. The index traffic fee of a Query Logstore is approximately half that of a Standard Logstore. Query Logstores do not support SQL analysis. Query Logstores are suitable for scenarios in which the amount of data is large, the log retention period is long, or log analysis is not required. If logs are stored for weeks or months, the log retention period is considered long.

Response parameters

Server	String	nginx	The name of the server.
Content-Type	String	application/json	The content type of the response body. Valid values: application/json and application/x-protobuf.
