Edge++: Datonis Edge

Edge++ Configuration on Datonis Edge:

Edge++ Service:

Edge++ Service offers support of Redis Data-store which is used for exchanging data between Edge and the Faas Framework. Edge++ Service lets us configure the settings related to the Redis store.

Send-to-Datonis:

• This flag is true if the events in the output-queue are to be transmitted to Datonis.
• Make this flag false if the data should not be transmitted to Datonis.

EdgeCloudService:

Once the access-key and secret-key are configured, set Enable Edge++ Setup flag to true. This will update the Datonis access-key in the Redis Store on save.

This will be used by the Rails framework to set up its components.

Thing Settings:

In Settings Tab for in any adapter configuration of a particular Thing, you can find the following Edge++ related settings.

1. Publish Mode - Send/scan Edge++: Sends the events (scan/send data, instruction, alerts) to the Redis input queue, and the FaasFunction will process and push the processed event into the Output queue.
2. Sync Edge++ Functions: This button populates the Data Process Function and the Instruction Process Function dropdown which are configured on the rails framework.
3. Data Process Function: Select the function which you want to use to process the thing’s data event.
4. Instruction Process Function: Select the function which you want to use to process the thing’s instruction event. You can select “--Not-Selected--” option which does not send instruction event to Redis.
