Enabling Log Backup or Log Collection

Function

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

Calling Method

For details, see Calling APIs.

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

  • 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

log_base_path

No

String

Definition:

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.

Value range:

  • 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

log_bucket

No

String

Definition:

OBS bucket name for log backup.

Constraints:

This parameter is mandatory when action is not set to real_time_log_collect.

Value range:

N/A

Default value:

N/A

N/A

target_cluster_id

No

String

Definition:

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.

Value range:

N/A

Default value:

N/A
