Edge AWS IoT Configuration
- Setup the AWS IoT Core account and download the certificate, AmazonCA1 and private key.
- Open Cloud Services and go to the AWS IoT Service Tab.
- Edit All the Necessary fields like aws-endpoint, private key etc.
- Select AWS from the edge.data-destination dropdown menu (This determines where to send data like to datonis or aws).
- Go to EdgeDataService Tab and change connect.use-http-transport to true to use the AWS IoT Service.
- Done.
AWS IoT Latency Calculation
Edge Sends a data-package to the AWS, each data-package can have multiple things data. The number of things data in a data-package can be configured through bulk_size. A data-package contains timestamp when it is ready to send whereas thing data contains individual thing scan timestamp, thing key, and data array.
Following will be the format for data :
{
"events": [
{
"thing_key": "ft26ecabad",
"timestamp": 1641561474351,
"data": {
"tag_1": 2542
},{
"thing_key": "jt77eczb2d",
"timestamp": 1641561474357,
"data": {
"tag_1": 2542
},
"data_faas_function": "",
"type": "data"
}
],
"timestamp": 1641795756303
}
Total time taken to deliver a data-package to destination that is time from scanning the very first thing data of the packet to till the acknowledge from the destination. To elaborate if data-package send timestamp is Send Timestamp[data-package], scan timestamp of very first thing data in the packet is Scan Timestamp[Thing1], time at which acknowledge received to Edge is Received Timestamp(acknowledge) then
Total time = (Send Timestamp[data-package] - Scan Timestamp[Thing1]) + (Received Timestamp[acknowledge] - Send Timestamp[data-package])
