# TD Agent Collecting Logs Through an Http Protocol

You can use HTTP to add logs from many places to Treasure Agent (td-agent).

* [Prerequisites](/products/customer-data-platform/integration-hub/streaming/td-agent/td-agent-collecting-logs-through-an-http-protocol#prerequisites)
* [Configuration](/products/customer-data-platform/integration-hub/streaming/td-agent/td-agent-collecting-logs-through-an-http-protocol#configuration)
* [Uploading Data via HTTP](/products/customer-data-platform/integration-hub/streaming/td-agent/td-agent-collecting-logs-through-an-http-protocol#uploading-data-via-http)


# Prerequisites

* Basic knowledge of Treasure Data, including the [TD Toolbelt](/tools/cli-and-sdks/td-toolbelt).


# Configuration

Add the following lines to your */etc/td-agent/td-agent.conf* file.


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

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

# Uploading Data via HTTP

You can add logs via HTTP by sending JSON data. Use the POST method and specify the database and table name by URL.


```bash
$ curl -X POST -d 'json={"action":"login","user":2}' \
http://localhost:8888/td.testdb.www_access
```

td-agent continuously uploads logs every minute. Sending a SIGUSR1 signal flushes the buffer. Uploads start immediately.


```bash
kill -USR1 `cat /var/run/td-agent/td-agent.pid`
```

To confirm that your data has been uploaded successfully, issue the *td tables* command as shown below.


```bash
$ td tables
+------------+------------+------+-----------+
| Database   | Table      | Type | Count     |
+------------+------------+------+-----------+
| testdb     | www_access | log  | 1         |
+------------+------------+------+-----------+
```

If you run into an issue, your log (/var/log/td-agent.log) is a good place to start troubleshooting.
