如何使用 Athena 查询我的应用程序负载均衡器连接日志？

解决方法

要查询应用程序负载均衡器连接日志，请为 Athena 创建数据库和表。完成以下步骤：

1. 打开 Athena 控制台。

2. 要创建数据库，请在 Query Editor（查询编辑器）中运行以下命令：

   CREATE DATABASE alb_db

   **注意：**最佳做法是在与 Amazon Simple Storage Service (Amazon S3) 存储桶相同的 AWS 区域中创建数据库。

3. 创建数据库后，使用以下查询创建表：

   CREATE EXTERNAL TABLE IF NOT EXISTS alb_connection_logs (  
            time string,  
            client_ip string,  
            client_port int,  
            listener_port int,  
            tls_protocol string,  
            tls_cipher string,  
            tls_handshake_latency double,  
            leaf_client_cert_subject string,  
            leaf_client_cert_validity string,  
            leaf_client_cert_serial_number string,  
            tls_verify_status string,  
            conn_trace_id string  
            )  
               PARTITIONED BY  
               (  
                day STRING  
               )  
               ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.RegexSerDe'  
               WITH SERDEPROPERTIES (  
               'serialization.format' = '1',  
               'input.regex' =  
                '([^ ]*) ([^ ]*) ([0-9]*) ([0-9]*) ([A-Za-z0-9.-]*) ([^ ]*) ([-.0-9]*) \"([^\"]*)\" ([^ ]*) ([^ ]*) ([^ ]*) ?([^ ]*)?( .*)?'  
               )  
               LOCATION 's3://S3-LOCATION/AWSLogs/ACCOUNT-NUMBER/elasticloadbalancing/REGION/'  
               TBLPROPERTIES  
               (  
                "projection.enabled" = "true",  
                "projection.day.type" = "date",  
                "projection.day.range" = "2023/01/01,NOW",  
                "projection.day.format" = "yyyy/MM/dd",  
                "projection.day.interval" = "1",  
                "projection.day.interval.unit" = "DAYS",  
                "storage.location.template" = "s3://S3-LOCATION/AWSLogs/ACCOUNT-NUMBER/elasticloadbalancing/REGION/${day}"  
               )

   **注意：**将 S3-LOCATION、ACCOUNT-NUMBER 和 REGION 替换为您的 S3 存储桶值。

4. 要查询应用程序负载均衡器连接日志，请使用 SQL 语句。

查询示例

查看最近 100 次出现的日志

SELECT *FROM alb_conn_logs  
ORDER by time desc  
LIMIT 100

计算 tls_verify_status 不是“Success”的出现次数，并按 client_IP 分组

SELECT distinct client_ip, count() as count from alb_conn_logs WHERE tls_verify_status != 'Success'  
GROUP by client_ip  
ORDER by count() DESC;

查看在特定时间范围内所有出现 tls_handshake_latency 超过两秒的情况

SELECT * FROM alb_conn_logs WHERE (parse_datetime(time,'yyyy-MM-dd''T''HH:mm:ss.SSSSSS''Z')  
BETWEEN parse_datetime('2024-01-01-00:00:00','yyyy-MM-dd-HH:mm:ss')  
AND parse_datetime('2024-03-20-00:00:00','yyyy-MM-dd-HH:mm:ss'))  
AND (tls_handshake_latency >= 2.0);

检查连接是否有准确的认证有效日期，并按 leaf_client_cert_serial_number 分组

SELECT DISTINCT leaf_client_cert_serial_number, count() AS count FROM alb_conn_logs  
WHERE tls_verify_status = 'Success' AND leaf_client_cert_validity like '%NotAfter=2025-01-01%'  
GROUP BY leaf_client_cert_serial_number  
ORDER BY count() DESC;
