<a name="vpc-query-examples-sourceversion2"></a>

Amazon Virtual Private Cloud (Amazon VPC) fournit des informations sur le trafic IP à destination et en provenance des interfaces réseau de votre VPC.

Voici quelques exemples de requêtes pour Amazon VPC Flow Logs pour la version AWS source 2 :

**Trafic en particulier Régions AWS au cours des 7 derniers jours**

```
SELECT *
    FROM "amazon_security_lake_glue_db_us_east_1"."amazon_security_lake_table_us_east_1_vpc_flow_2_0"
WHERE time_dt BETWEEN CURRENT_TIMESTAMP - INTERVAL '7' DAY AND CURRENT_TIMESTAMP 
AND region in ('us-east-1','us-east-2','us-west-2')
LIMIT 25
```

**Liste des activités depuis l'adresse IP `192.0.2.1` et le port source `22` au cours des 7 derniers jours**

```
SELECT *
FROM "amazon_security_lake_glue_db_us_east_1"."amazon_security_lake_table_us_east_1_vpc_flow_2_0"

AND src_endpoint.ip = '192.0.2.1'
AND src_endpoint.port = 22
LIMIT 25
```

**Nombre d'adresses IP de destination distinctes au cours des 7 derniers jours**

```
SELECT 
    COUNT(DISTINCT dst_endpoint.ip) AS "Total"

LIMIT 25
```

**Trafic provenant de 198.51.100.0/24 au cours des 7 derniers jours**

LIMIT 25
```

**Tout le trafic entre IP `192.0.2.1` et `192.0.2.2` au cours des 7 derniers jours**

```

LIMIT 25
```

**Tout le trafic entrant au cours des 7 derniers jours**
