Input Processors

8min

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.

Database Batch Input Processors

Database Batch Input Overview

  • 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

Database Batch Input Parameters

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.

Generator Processors

Generator Overview

  • Simple generator for testing, use t as the variable.

Generator Parameters

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.
