+This tutorial introduces securely sending data from Mbed OS devices to Arm Treasure Data using two methods:
 
 - HTTPS library - Send data directly to the Treasure Data REST API.
 - Fluentd using fluent logger library - Send data to a hosted Fluentd instance that aggregates and forwards the data on to your treasure data account.

 To use the HTTPS library, use the [mbed-os-example-treasuredata-rest](https://github.com/blackstoneengineering/mbed-os-example-treasuredata-rest) program. This program turns on Mbed OS device statistics by enabling the `MBED_ALL_STATS_ENABLED` macro and then sends heap/CPU/stack/system information to Treasure Data.

 If you are running the Fluentd server locally on your machine to develop a proof of concept (PoC), you need to generate a new self-signed certificate (where the Common Name (CN) is the IP address of your machine), and modify the `fluentd.conf` file with the IP address of your machine. Each time you restart the Fluentd instance, it generates a new certificate that you need to copy and paste into your embedded code.
