Query Configuration
Graph view
To visualize the observations from OGC SensorThings server,
- Add a graph panel.
- Select the SensorThings Datasource.
- Select
SensororThingsto get the list of sensors or things which are available in your SensorThings server. - Select a specific sensor or thing from the list, to get the list of datastreams.
- Select a datastream to visualize the observations in the graph.
See the demo below for better understanding:
Table view
Using table view, one can see list of observation recorded based on Sensors/Things, and also list of Locations visited by a Thing or list of Things that has been in a specific Location.
- Add a table panel.
- Select the SensorThings Datasource.
- Select
Sensors,Things,Locations, orHistorical Locationsfrom the initial dropdown list.
See the demo below for better understanding:
World Map view
Using world map view, one can see the current Location of a Thing on the map.
Install world map panel from grafana plugin store.
Add a world map panel in dashboard
In "Worldmap" tab:
- Select
Center->Last GeoHash - Set
Min Circle SizeandMax Circle Sizeto 5 - Select
Location Data->json result
- Select
