Description
Aggregator is a processing module responsible for aggregating data passing through weeve data services. Aggregator collects data within a time interval specified by a data service developer, and then it applies a chosen aggregation function. This module is containerized using Docker.
Supported functions:
- mean (mean value that arrived within the specified interval)
- max (maximum value)
- spread (maximum - minimum value)
- median (median value recorded within the interval)
- sum (sum of all received values)
- stddv (standard deviation of values)
- count (number of data that arrived within the interval)
- first (first recorded data)
- min (minimum value)
- last (last recorded data)
Environment Variables
Module Specific
The following module configurations can be provided in a data service designer section on weeve platform:
| Name | Environment Variables | type | Description |
|---|---|---|---|
| Interval Unit | INTERVAL_UNIT | string | The unit for time interval (ms, s, m, h, d) |
| Interval Period | INTERVAL_PERIOD | integer | The time interval on which aggregation will be applied |
| Function | FUNCTION | string | Aggregation function to apply (mean, max, spread, median, sum, stddv, count, first, min, last) |
| Input Label | INPUT_LABEL | string | The input label on which anomaly is detected |
| Output Label | OUTPUT_LABEL | string | The output label as which data is dispatched |
Set by the weeve Agent on the edge-node
Other features required for establishing the inter-container communication between modules in a data service are set by weeve agent.
| Environment Variables | type | Description |
|---|---|---|
| MODULE_NAME | string | Name of the module |
| MODULE_TYPE | string | Type of the module (Input, Processing, Output) |
| EGRESS_URL | string | HTTP ReST endpoint for the next module |
| INGRESS_HOST | string | Host to which data will be received |
| INGRESS_PORT | string | Port to which data will be received |
Dependencies

Input
Input to this module is JSON body single object:
Example:
json{ temperature: 15, input_unit: Celsius }
Output
Output of this module is JSON body array of objects.
Output of this module is JSON body:
json{ "<OUTPUT_LABEL>": <Processed data>, }
- Here
OUTPUT_LABELis specified at the module creation andProcessed datais data processed by Module Main function.
Example:
json{ meanTemp: 54.7, }
