如何使用 Athena 查詢 Application Load Balancer 連線日誌？

解決方法

若要查詢Application Load Balancer 連線日誌，請為 Athena 建立資料庫和資料表。請完成下列步驟：

1. 開啟 Athena console (Athena 主控台)。

2. 若要建立資料庫，請在查詢編輯器中執行下列命令：

   CREATE DATABASE alb_db

   **注意：**最佳實務是在與您的 Amazon Simple Storage Service (Amazon S3) 儲存貯體相同的 AWS 區域中建立資料庫。

3. 建立資料庫後，請使用下列查詢建立資料表：

   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：**將 S3-LOCATION、ACCOUNT-NUMBER 和 REGION 替換為您的 S3 儲存貯體值。

4. 若要查詢 Application Load Balancer 連線日誌，請使用 SQL 陳述式。

範例查詢

查看最近 100 比日誌

SELECT *FROM alb_conn_logs  
ORDER by time desc  
LIMIT 100

統計 tls_verify_status 不為「成功」的次數，並依 client_IP 分組

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

查看特定時間範圍內，所有 tls_handshake_latency 超過兩秒的情況

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);

檢查具有確切憑證有效期的連線，並依leaf_client_cert_serial_number 分組

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;
