he Device-to-Cloud (D2C) message policy allows you to transform default payload to your desired payload schema via the jq filter. For additional information, refer to the jq website at https://stedolan.github.io/jq/manual/.

Enabling Store and Forward​

D2C messages can be cached in a specified location and sent to the cloud later. This feature will help you store the acquired data temporarily in a queue when the network between your IIoT Gateway and the cloud is disconnected and re-transmit the data to its destination after reconnecting. To enable the function, click on the Store and Forward tab and select Enable Store and Forward. You can select a target disk and set a maximum storage cache, set a retention policy, and a TTL (Time to Live) value for the messages.
