# 监控数据加载
Aurora PostgreSQL Limitless Database 提供了多种监控数据加载任务的方式：
+ [列出数据加载任务](#limitless-load.monitor-list)
+ [使用任务 ID 查看数据加载任务的详细信息](#limitless-load.monitor-describe)
+ [监控 Amazon CloudWatch 日志组](#limitless-load.monitor-cwl)
+ [监控 RDS 事件](#limitless-load.monitor-events)
## 列出数据加载任务
您可以连接到集群端点，然后使用 `rds_aurora.limitless_data_load_jobs` 视图列出数据加载任务。
```
postgres_limitless=> SELECT * FROM rds_aurora.limitless_data_load_jobs LIMIT 6;

任务记录将在 90 天后删除。
## 使用任务 ID 查看数据加载任务的详细信息
如果您知道任务 ID，则可以连接到集群端点，然后使用 `rds_aurora.limitless_data_load_job_details` 视图查看该数据加载任务的详细信息，包括表名称、任务状态和已加载的行数。您可以在对数据加载启动函数的响应中获取任务 ID，也可以从 `rds_aurora.limitless_data_load_jobs` 视图中获取。
```
postgres_limitless=> SELECT * FROM rds_aurora.limitless_data_load_job_details WHERE job_id='1725696114225';
job_id | destination_table_name | destination_schema_name | start_time | status | full_load_rows | full_load_total_rows | full_load_complete_time | cdc_insert | cdc_update | cdc_delete

任务记录将在 90 天后删除。
## 监控 Amazon CloudWatch 日志组
数据加载任务状态更改为 `RUNNING` 后，您可以使用 Amazon CloudWatch Logs 查看运行进度。
**监控 CloudWatch 日志流**
登录 AWS 管理控制台并打开 CloudWatch 控制台（[https://console.aws.amazon.com/cloudwatch/](https://console.aws.amazon.com/cloudwatch/)）。
1. 导航到**日志**，然后导航到**日志组**。
1. 选择 **/aws/rds/aurora-limitless-database** 日志组。
1. 通过 **job\$1id** 搜索您的数据加载任务的日志流。
日志流的模式为 **Data-Load-Job-*job\$1id***。
1. 选择日志流以查看日志事件。
每个日志流都显示包含任务状态和已加载到 Aurora PostgreSQL Limitless Database 目标表中的行数的事件。如果数据加载任务失败，还会创建错误日志，显示失败状态和原因。
任务记录将在 90 天后删除。
## 监控 RDS 事件
数据加载任务还会发布 RDS 事件，例如当任务成功、失败或取消时。您可以查看目标数据库中的事件。
