Command parameters

The following table describes the required parameters of this command and the parameters that are specific to this command.

Parameter	Type	Required	Example	Description
--project_name	String	Yes	aliyun-test-project	The name of the project.
--logstore_name	String	Yes	logstore-a	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.
--ttl	Integer	No	30	The retention period of data. Unit: days. Valid values: 1 to 3650. If you set this parameter to 3650, data is permanently stored.
--shard_count	Integer	No	2	The number of shards. Valid values: 1 to 10.
--enable_tracking	Boolean	No	true	Specifies whether to enable the web tracking feature. Default value: false. Valid values: true false
--append_meta	Boolean	No	false	Specifies whether to record public IP addresses. Default value: false. Valid values: true false
--auto_split	Boolean	No	true	Specifies whether to enable automatic sharding. Default value: false. Valid values: true false
--max_split_shard	Integer	No	64	The maximum number of shards into which existing shards can be automatically split. Valid values: 1 to 256. If you set --autoSplit to true, you must specify this parameter.
--encrypt_conf	String	No	None	The data structure of the encryption configuration. For more information, see EncryptConf.
--telemetry_type	String	No	None	The type of the observable data. Valid values: None (default): logs Metrics: metrics
--hot_ttl	Integer	No	60	The retention period of data in the hot storage tier of the Logstore. Unit: days. Valid values: 7 to 3000. Hot data that is stored for longer than the period specified by hot_ttl is converted to cold data. For more information, see Enable hot and cold-tiered storage for a Logstore.
--mode	String	No	standard	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.
