CreateLogStore - Simple Log Service - Alibaba Cloud Documentation Center

Creates a Logstore.

Operation description

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 Resource Access Management (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 each 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

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation
log:CreateLogStore	create	LogStore acs:log:{#regionId}:{#accountId}:project/{#project}/logstore/{#logstoreName}	log:TLSVersion log:Encrypted	none

Request syntax

POST /logstores HTTP/1.1

Request parameters

Parameter	Type	Required	Description	Example
project	string	Yes	The name of the project.	ali-test-project
body	object	Yes	The request body.
logstoreName	string	Yes	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.	my-logstore
shardCount	integer	Yes	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.	2
ttl	integer	Yes	The retention period of data. Unit: days. Valid values: 1 to 3000. If you set this parameter to 3650, data is permanently stored.	1
encrypt_conf	EncryptConf	No	The data structure of the encryption configuration. The following parameters are included: `enable`, `encrypt_type`, and `user_cmk_info`. For more information, see EncryptConf .
autoSplit	boolean	No	Specifies whether to enable automatic sharding. Valid values: true false	true
enable_tracking	boolean	No	Specifies whether to enable the web tracking feature. Default value: false. Valid values: true false	false
maxSplitShard	integer	No	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 this parameter.	64
appendMeta	boolean	No	Specifies whether to record the public IP address and log receiving time. Default value: false. Valid values: true****** false******	false
telemetryType	string	No	The type of the observable data. Valid values: None (default): log data Metrics: metric data	None
hot_ttl	integer	No	The retention period of data in the hot storage tier of the Logstore. Valid values: 7 to 3000. Unit: days. After the retention period that is specified for the hot storage tier elapses, the data is moved to the Infrequent Access (IA) storage tier. For more information, see Enable hot and cold-tiered storage for a Logstore.	60
mode	string	No	The type of the Logstore. Simple Log Service provides two types of Logstores: Standard Logstores and Query Logstores. Valid values: 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.	standard
infrequentAccessTTL	integer	No	The retention period of data in the IA storage tier of the Logstore. You must set this parameter to at least 30 days. After the data retention period that you specify for the IA storage tier elapses, the data is moved to the Archive storage tier.	30

Response parameters
