# Revisione dei log del server Appium
Dopo aver [avviato una sessione Appium](appium-endpoint-interaction.md), puoi visualizzare i log del server Appium in tempo reale nella console Device Farm o scaricarli al termine della sessione di accesso remoto. Ecco le istruzioni per farlo:
------
#### [ Console ]
1. Nella console Device Farm, apri la sessione di accesso remoto per il tuo dispositivo.
1. Avvia una sessione di endpoint Appium con il dispositivo dall'IDE locale o da Appium Inspector
1. Quindi, il registro del server Appium verrà visualizzato accanto al dispositivo nella pagina della sessione di accesso remoto, con le «informazioni sulla sessione» disponibili nella parte inferiore della pagina sotto il dispositivo:
![\[\]](http://docs.aws.amazon.com/it_it/devicefarm/latest/developerguide/images/aws-device-farm-appium-endpoint-logs.gif)
------
#### [ AWS CLI ]
*Nota: questo esempio utilizza lo [strumento da riga di comando `curl`](https://curl.se/) per estrarre il registro da Device Farm.*
Durante o dopo la sessione, puoi utilizzare l'[https://docs.aws.amazon.com/devicefarm/latest/APIReference/API_ListArtifacts.html](https://docs.aws.amazon.com/devicefarm/latest/APIReference/API_ListArtifacts.html)API di Device Farm per scaricare il log del server Appium.
```
$ 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
```
Questo mostrerà un output come il seguente durante la sessione:
```
{
"artifacts": [
{
"arn": "arn:aws:devicefarm:us-west-2:111122223333:artifact:12345678-1111-2222-333-456789abcdef/12345678-1111-2222-333-456789abcdef/00000",
"name": "AppiumServerLogOutput",
"type": "APPIUM_SERVER_LOG_OUTPUT",
"extension": "",
"url": "https://prod-us-west-2-results.s3.dualstack.us-west-2.amazonaws.com/111122223333/12345678..."
}
]
}
```
E quanto segue al termine della sessione:
```
{
"artifacts": [
{
"arn": "arn:aws:devicefarm:us-west-2:111122223333:artifact:12345678-1111-2222-333-456789abcdef/12345678-1111-2222-333-456789abcdef/00000",
"name": "Appium Server Output",
"type": "APPIUM_SERVER_OUTPUT",
"extension": "log",
"url": "https://prod-us-west-2-results.s3.dualstack.us-west-2.amazonaws.com/111122223333/12345678..."
}
]
}
```
```
$ curl "https://prod-us-west-2-results.s3.dualstack.us-west-2.amazonaws.com/111122223333/12345678..."
```
Questo mostrerà un output come il seguente:
```

```

#### [ Python ]
*Nota: questo esempio utilizza il `requests` pacchetto di terze parti per scaricare il registro, oltre all' AWS SDK per Python`boto3`.*
Durante o dopo la sessione, puoi utilizzare l'[https://docs.aws.amazon.com/devicefarm/latest/APIReference/API_ListArtifacts.html](https://docs.aws.amazon.com/devicefarm/latest/APIReference/API_ListArtifacts.html)API di Device Farm per recuperare l'URL del registro del server Appium, quindi scaricarlo.
```

# Filter strictly to Appium server logs

if not filtered:

# Prefer the final 'OUTPUT' log, else the live 'LOG_OUTPUT'

Questo mostrerà un output come il seguente:
