Querying ARDI Data
To make Grafana charts using ARDI data, you'll need to choose your ARDI data source when setting up a Grafana channel.
A query is made up of several options….
Type
There are a few different types of request.
| Type Name | Effect |
|---|---|
| Current Point | Shows the current/live values of a single asset, no matter what time range is chosen |
| Point | Shows the values of measurements from a single asset |
| Query | Shows the results from an AQL query |
| Selector | Shows the results from an ARDI point selector |
| Table | Experimental For table-based Grafana visualisations of properties |
For examples of these, see Query Types.
Context
The ARDI context you want to query from. You may choose between any of the configured ARDI contexts. Defaults to Actual.
Point/Query/Selector
This varies based on query type, but contains either the name of the data point in 'asset.property' format, the selector to use, or the AQL query to use.
Start typing and the system will help you auto-complete all but the AQL query.
Examples
Example Queries are available.
