Function

This API is used to enable the log backup or collection function of a cluster. Log backup and log collection can be enabled separately. After log backup is enabled, you can configure an automatic backup policy or manually trigger backup to back up cluster run logs to a specified OBS bucket and directory. After the real-time log collection function is enabled, cluster logs are collected to the specified index of the specified CSS cluster in real time.

Calling Method

For details, see Calling APIs.

URI

POST /v1.0/{project_id}/clusters/{cluster_id}/logs/open

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Parameter description: Project ID. For details about how to obtain the project ID and name, see Obtaining the Project ID and Name. Constraints: N/A Options: For details about how to obtain the project ID and name, see Obtaining the Project ID and Name. Default value: N/A
cluster_id	Yes	String	Parameter description: Specifies the ID of the cluster for which you want to enable log backup or log collection. For details about how to obtain the cluster ID, see Obtaining a Cluster ID. Constraints: N/A Options: For details about how to obtain the cluster ID, see Obtaining the Cluster ID. Default value: N/A

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
action	No	String	Parameter description: Configure log backup or log collection for a cluster. Constraints: N/A Options: base_log_collect: Backs up logs to OBS. real_time_log_collect: Saves logs to an Elasticsearch cluster in real time. Default value: base_log_collect

Request Parameters

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
agency	No	String	Parameter description: Agency name. Through this agency, you delete OBS permissions to CSS, so that CSS will be able to back up log files to your OBS buckets. Constraints: This parameter is mandatory when action is not set to real_time_log_collect. Options: The value can contain only letters (a-z and A-Z), digits (0-9), hyphens (-), and underscores (_). It cannot contain Chinese characters or other special characters. Default value: N/A
logBasePath	No	String	Parameter description: Storage path of backed up logs in the OBS bucket. Constraints: This parameter is mandatory when action is not set to real_time_log_collect. Options: The backup path cannot contain the following characters: \:?"<>\|'{}. Additionally, it cannot: Start with a slash (/). Start or end with a period (.). Contain more than two consecutive slashes (/) or periods (.). Exceed 512 characters. Default value*: N/A
logBucket	No	String	Parameter description: OBS bucket name for log backup. Constraints: This parameter is mandatory when action is not set to real_time_log_collect. Options: N/A Default value: N/A
index_prefix	No	String	Parameter description: Index prefix for storing logs. Constraints: This parameter is mandatory when action is set to real_time_log_collect. Options: N/A Default value: N/A
keep_days	No	Integer	Parameter description: Number of days for log retention. Constraints: This parameter is mandatory when action is set to real_time_log_collect. Options: 1-3650 Default value: N/A
target_cluster_id	No	String	Parameter description: ID of the target cluster for log storage. Constraints: The target cluster can be the current cluster or another Elasticsearch cluster. If logs are saved to another cluster, you need to use the connectivity testing API to test connectivity to the target cluster. If status code 200 is returned, the target cluster can be reached. Otherwise, you need to select another target cluster. This parameter is mandatory when action is set to real_time_log_collect. Options: N/A Default value: N/A
