# Setting Up TD Agent

After installing Treasure Agent `(td-agent)`, you can modify your config file. The file can be found in /etc/td-agent/td-agent.conf.

The config file comes with some sample settings. You will find the following lines in your config. Specify your API key by setting the `apikey` option. You can view your API key from the TD Console.


```conf
# HTTP input
<source>
  type http
  port 8888
</source>

# Treasure Data output
<match td.*.*>
  type tdlog
  endpoint api-import.treasuredata.com
  apikey YOUR_API_KEY
  auto_create_table
  buffer_type file
  buffer_path /var/log/td-agent/buffer/td
  use_ssl true
  num_threads 8
</match>
```

`YOUR_API_KEY` should be your actual apikey string. You can retrieve your API key from your profiles in TD Console. Using a [write-only API key](/products/my-settings/getting-your-api-keys) is recommended.

# Restart the td-agent Service


```bash
# Linux
sudo /etc/init.d/td-agent restart

# macOS
sudo launchctl unload /Library/LaunchDaemons/td-agent.plist
sudo launchctl load /Library/LaunchDaemons/td-agent.plist
```
