# Log

Descrive dove vengono archiviati i file di log della traccia delle richieste non riuscite in IIS e come aprire i file di traccia XML per diagnosticare gli errori di Devolutions Server.

Con la traccia delle richieste non riuscite abilitata, i file di log vengono creati e popolati nella directory configurata in [Configurare la traccia delle richieste non riuscite](/server/it/knowledge-base/troubleshooting-articles/failed-request-tracing-with-iis/configuration.md). Per impostazione predefinita, il percorso è **%SystemDrive%\inetpub\logs\FailedReqLogFiles**. Lì viene creata una cartella generalmente denominata **W3SVC1** quando si verifica il primo caso.

### Contenuto della cartella W3SVC1

* File XML (**fr######.xml**): apra un file XML per visualizzare il log attivato dalla regola di traccia.
* File XSL (**freb.xsl**): per lo stile di visualizzazione, in un visualizzatore XML come Internet Explorer.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/server/it/knowledge-base/troubleshooting-articles/failed-request-tracing-with-iis/logs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
