Fastly's [Real-Time Log Streaming](https://www.fastly.com/documentation/guides/integrations/streaming-logs/about-fastlys-realtime-log-streaming-features) feature can send log files to [OpenStack](https://www.openstack.org/). OpenStack is an open-source platform for cloud-computing that many companies deploy as an infrastructure-as-a-service.

## Adding OpenStack as a logging endpoint

Follow these instructions to add OpenStack as a logging endpoint:

### Cdn Services

1.   Review the information in our guide to [setting up remote log streaming](/guides/integrations/streaming-logs/setting-up-remote-log-streaming).

2. In the OpenStack area, click **Create endpoint**.
3. Fill out the **Create an OpenStack endpoint** fields as follows:
   -   In the **Name** field, enter a human-readable name for the endpoint.

   -   In the **Placement** area, select where the logging call should be placed in the generated VCL. Valid values are **Format Version Default** and **None**. Read our guide on [changing log placement](/guides/integrations/streaming-logs/changing-log-placement) for more information.

   -   In the **Log format** field, optionally enter an Apache-style string or VCL variables to use for log formatting. Consult the [example format section](#example-format) for details.

   -   *(Optional)* In the **Timestamp format** field, enter a timestamp format for log files. The default is an `strftime` compatible string. Our guide on [changing where log files are written](/guides/integrations/streaming-logs/changing-where-log-files-are-written) provides more information.

   - In the **Auth URL** field, enter the URL used for OpenStack authentication (e.g., `https://auth.api.rackspacecloud.com/v1.0`).
   - In the **Bucket name** field, enter the name of the OpenStack bucket in which to store the logs.
   - In the **User** field, enter your OpenStack username.
   - In the **Access Key** field, enter your OpenStack access key.
   -   *(Optional)* In the **Period** field, enter an interval (in seconds) to control how frequently your log files are rotated. Rotation entails the finalization of one file object and the start of a new one, never removing any previously created file object. This value defaults to `3600` seconds.

   -   *(Optional)* From the **Processing region** menu, select a geographic region where logs are processed before being sent to the logging endpoint. Our guide on [regional log aggregation](/guides/integrations/streaming-logs/setting-up-regional-log-aggregation) provides more information.

4. Click **Advanced options** and fill out the fields as follows:
   -   *(Optional)* In the **Path** field, enter the path within the bucket to store the files. The path ends with a trailing slash. If this field is left empty, the files will be saved in the bucket's root path. Our guide on [changing where log files are written](/guides/integrations/streaming-logs/changing-where-log-files-are-written) provides more information.

   -   *(Optional)* In the **PGP public key** field, enter a PGP public key that Fastly will use to encrypt your log files before writing them to disk. You will only be able to read the contents by decrypting them with your private key. The PGP key should be in [PEM (Privacy-Enhanced Mail) format](https://en.wikipedia.org/wiki/Privacy-enhanced_Electronic_Mail). Read our guide on [log encryption](/guides/integrations/streaming-logs/encrypting-logs) for more information.

   -   In the **Select a log line format** area, select the log line format for your log messages. Our guide on [changing log line formats](/guides/integrations/streaming-logs/changing-log-line-formats) provides more information.

   -   *(Optional)* In the **Compression** field, select the compression format you want applied to the log files. Our guide on [changing log compression options](/guides/integrations/streaming-logs/changing-log-compression-options) provides more information.

5.   Click **Create** to create the new logging endpoint.

6.   From the **Activate** menu, select **Activate on Production** to deploy your configuration changes.

### Example format

The following is an example format string for sending data to OpenStack. Our discussion of [format strings](https://www.fastly.com/documentation/guides/integrations/streaming-logs/custom-log-formats) provides more information.

```plaintext
{
  "timestamp": "%{strftime(\{"%Y-%m-%dT%H:%M:%S%z"\}, time.start)}V",
  "client_ip": "%{req.http.Fastly-Client-IP}V",
  "geo_country": "%{client.geo.country_name}V",
  "geo_city": "%{client.geo.city}V",
  "host": "%{if(req.http.Fastly-Orig-Host, req.http.Fastly-Orig-Host, req.http.Host)}V",
  "url": "%{json.escape(req.url)}V",
  "request_method": "%{json.escape(req.method)}V",
  "request_protocol": "%{json.escape(req.proto)}V",
  "request_referer": "%{json.escape(req.http.referer)}V",
  "request_user_agent": "%{json.escape(req.http.User-Agent)}V",
  "response_state": "%{json.escape(fastly_info.state)}V",
  "response_status": %{resp.status}V,
  "response_reason": %{if(resp.response, "%22"+json.escape(resp.response)+"%22", "null")}V,
  "response_body_size": %{resp.body_bytes_written}V,
  "fastly_server": "%{json.escape(server.identity)}V",
  "fastly_is_edge": %{if(fastly.ff.visits_this_service == 0, "true", "false")}V
}
```

### Compute Services

1.   Review the information in our guide to [setting up remote log streaming for Compute](/guides/integrations/streaming-logs/setting-up-remote-log-streaming-for-compute). Additionally, our developer documentation provides more [information about logging](/guides/integrations/non-fastly-services/developer-guide-logging/) with Compute code written in our [supported languages](/reference/compute/sdks/).

2. In the OpenStack area, click **Create endpoint**.
3. Fill out the **Create an OpenStack endpoint** fields as follows:
   -   In the **Name** field, enter the endpoint name you specified in your Compute code. For example, in our [Rust code example](/guides/compute/developer-guides/rust/#logging), the name is `my_endpoint_name`.

   -   *(Optional)* In the **Timestamp format** field, enter a timestamp format for log files. The default is an `strftime` compatible string. Our guide on [changing where log files are written](/guides/integrations/streaming-logs/changing-where-log-files-are-written) provides more information.

   - In the **Auth URL** field, enter the URL used for OpenStack authentication (e.g., `https://auth.api.rackspacecloud.com/v1.0`).
