# Appium サーバーログの確認
[Appium セッションを開始すると](appium-endpoint-interaction.md)、Device Farm コンソールで Appium サーバーログをライブで表示したり、リモートアクセスセッションが終了した後にダウンロードしたりできます。これを行う手順は次のとおりです。
------
#### [ Console ]
1. Device Farm コンソールで、デバイスのリモートアクセスセッションを開きます。
1. ローカル IDE または Appium Inspector からデバイスで Appium エンドポイントセッションを開始する
1. 次に、Appium サーバーログがリモートアクセスセッションページにデバイスとともに表示され、デバイスの下のページの下部に「セッション情報」が表示されます。

------
#### [ AWS CLI ]
*注: この例では、 [コマンドラインツールを使用して `curl`](https://curl.se/) Device Farm からログをプルします。*
セッション中またはセッション後に、Device Farm の [https://docs.aws.amazon.com/devicefarm/latest/APIReference/API_ListArtifacts.html](https://docs.aws.amazon.com/devicefarm/latest/APIReference/API_ListArtifacts.html) API を使用して Appium サーバーログをダウンロードできます。
```
$ aws devicefarm list-artifacts \
--type FILE \
--arn arn:aws:devicefarm:us-west-2:111122223333:session:12345678-1111-2222-333-456789abcdef/12345678-1111-2222-333-456789abcdef/00000
```
これにより、セッション中に次のような出力が表示されます。
```
{
"artifacts": [
{
"arn": "arn:aws:devicefarm:us-west-2:111122223333:artifact:12345678-1111-2222-333-456789abcdef/12345678-1111-2222-333-456789abcdef/00000",

}
]
}
```
セッションが完了したら、以下を実行します。
```

"artifacts": [
{
"arn": "arn:aws:devicefarm:us-west-2:111122223333:artifact:12345678-1111-2222-333-456789abcdef/12345678-1111-2222-333-456789abcdef/00000",

}
```

これにより、次のような出力が表示されます。
```
