Input Processors
The Analytics module makes use of built-in Input processors to retrieve data from a topic, database, or generator.
The following describes the input processors that are currently available.
- Generate events by periodically polling specified DB measurements.
- Filtering:
- You could add filtering for queries.
- List of fields depends on database and measurement, but for device data, standard filters are: datatype, device_id, is_device_status, register_id, success, tag, topic, value.
- Examples:
- Filter by tag: "tag" = 'tag1'
- Filter by tag and success: "tag" = 'tag1' AND "success" = 1
Parameters | Details |
---|---|
Database | Select the name of the database from which data will be retrieved. |
Filter | Specify the SQL filter for the WHERE part of the query to filter the data from the database. |
Metric Name | Name of the metric for TimeSeriesDB polling. |
Period Secs | Set the polling interval in seconds for retrieving data from the database. |
Typed | Define the data typed policy for processing the retrieved data. |
- Generate events from specified DataHub topic and attach to output.
Parameters | Details |
---|---|
Format | Choose the format of the data, with possible values of json or fb (flat buffer). |
Topic | Select the specific device and tag from which data will be collected. |
Ignore Failed Data (Manufacturing Connect Edge version 3.11.0 and later) | Select to ignore data with the output success=false. |
Ignore Null Value (Manufacturing Connect Edge version 3.11.0 and later) | Select to ignore data with the output value=null. |
- Simple generator for testing, use t as the variable.
Parameters | Details |
---|---|
Amplitude Multiplier | Specify the amplitude multiplier for the generated signal. |
Formula | Choose the supported math functions for generating the signal, such as sin, cos, tan, power, sqrt, log, exp, or abs. |
Generator Type | User defined signal generation or pre-defined generation. |
Periodicity | Define the periodicity of the signal in seconds. |
Strength | Specify the strength of the simulated wave approximation, with the maximum value being 10. |
Timer Interval | Set the timer in milliseconds. If no event occurs, this timer is used to keep displaying the output continually. Enter zero to disable the timer. |
