The Dataset List query retrieves all available datasets from your datasource within a selected time range.
Your query should support the following optional filters:
timestamp_start – (Optional) - The start time of the selection (Unix epoch in seconds) .
timestamp_stop – (Optional) - The end time of the selection (Unix epoch in seconds).
metadata – (Optional) - A dictionary of key-value pairs for filtering datasets based on metadata, e.g., {‘outing’: [‘O1’, ‘O2’], ‘car’: [‘car1’]}.
Each dataset should be represented as a row containing:
display_name (Required) – A user-friendly dataset name.
timestamp_start (Required) – The timestamp of the first datapoint in the dataset.
timestamp_stop (Required) – The timestamp of the last datapoint in the dataset.
realtime (Optional, default: False) – A flag indicating whether the dataset contains real-time data.
Additional metadata fields (Optional) – Any relevant metadata attributes.
The Signal List query retrieves all available signals within a given dataset.
Your query should support the following:
dataset (Required) – A key-value pair for each metadata key checked in the dataset filter. Used in queries as {{ dataset.id }}.
Each signal should be represented as a row containing:
name (Required) – The name of the signal.
count (Optional) – The number of records in the signal.
frequency (Optional) – The frequency of measured datapoints.
unit (Optional) – The unit of measurement for the signal.
Additional metadata fields (Optional) – Any relevant metadata attributes.
The Time Series query retrieves time-series data for a single signal within a given dataset and time range.
Your query should accept the following inputs:
dataset (Required) – A key-value pair for each metadata key checked in the dataset filter. Used in queries as {{ dataset.id }}.
signal (Required) – A key-value pair where name is the signal name. Used in queries as {{ signal.name }}.
timestamp_start (Optional) – The start time of the time series in Unix epoch seconds.
timestamp_stop (Optional) – The end time of the time series in Unix epoch seconds.
Each row of the query output should contain:
name (Required) – The name of the signal.
timestamp (Required) – The timestamp of the data point in Unix epoch seconds.
value (Required) – The measured value of the signal.
