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 [Loggly](https://www.loggly.com/). Loggly is an agent-less log collection and management tool.

## Prerequisites

If you don't already have a Loggly account, you'll need to register for one. Follow the [signup instructions](https://www.loggly.com/signup/) on the Loggly website.

Follow the steps below to find your Loggly customer token:

1. Navigate to the **[Customer Tokens](https://documentation.solarwinds.com/en/success_center/loggly/content/admin/customer-token-authentication-token.htm)** area in the **Source Setup** on your Loggly dashboard.

2. Make note of your Loggly customer token. Loggly uses this to associate data you send them with your account.

## Adding Loggly as a logging endpoint

After you've created a Loggly account and obtained your customer token, follow these instructions to add Loggly as a logging endpoint for Fastly services:

### 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 Loggly area, click **Create endpoint**.
3. Fill out the **Create a Loggly 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.

   - In the **Token** field, enter your Loggly customer token.
   -   *(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 **Create** to create the new logging endpoint.

5.   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 Loggly. 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 Loggly area, click **Create endpoint** button.
3. Fill out the **Create a Loggly 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`.

   - In the **Token** field, enter your Loggly customer token.
4.   Click **Create** to create the new logging endpoint.

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