# Confirming Data Upload

You can add logs in JSON format using HTTP.


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

`td-agent` continuously uploads logs every 5 minutes. You can force `td-agent` to flush the buffered logs into the cloud by sending a SIGUSR1 signal.


```bash
# Linux
$ kill -USR1 `cat /var/run/td-agent/td-agent.pid`
    
# MacOS X
$ sudo kill -USR1 `sudo launchctl list | grep td-agent | cut -f 1`
```

Go to TD Console > Databases to check if the data got imported successfully. Or from the CLI, you can check by issuing the `td tables` command:


```bash
$ td tables
```


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

If you run into any issues, the `td-agent` log (/var/log/td-agent/td-agent.log) is a good place to start your investigation.
