docker compose upGrafana is running at http://localhost:3000
Grafana default user/pass is admin/odala2, it can be changed in the settings
Under kubernetes/ there is a kustomization bundle.
Change the values through the overlay, then kubectl apply -k kubernetes/overlay
The dashboard will query Scorpio for entities of type OnStreetParking, OffStreetParking, RestrictedTrafficArea and GtfsStop. Info about the datamodels can be found here: https://github.com/smart-data-models
In the case of the city of Arezzo the data comes from the following extractors:
- https://gitlab.publiccode.solutions/odala/otp-stops-extractor
- https://gitlab.publiccode.solutions/odala/emixer-fetcher
Refer to those repositories if data can be ingested from the same providers.
The grafana datasource used to make NGSI-LD native queries is https://gitlab.publiccode.solutions/odala/ngsild-grafana-datasource .
This is a derivative of the original https://github.com/bfi-de/ngsild-grafana-datasource that works around a limitation of the method used to check the availability of the broker, which is Orion-LD specific.
Other quirks are:
- NGSI-LD does not mandate any endpoint that responds 200 with an empty broker (i.e. no entities), so the DS works only with non-empty brokers.
- Scorpio returns
attributeNames = <string>instead ofattributeNames = [<string>]. See ScorpioBroker/ScorpioBroker#381 - The datasource is stripping part of the path from the timeseries URL so we
must append
ngsi-ld/v1explicitly in the configuration
Prior to the current grafana-based solution another attempt was made to use a fiware-native dashboard https://github.com/triveme/smartcity-dashboard together with QuantumLeap but the software worked under specific conditions that cannot be met under the current technological stack. The experiment is archived in commit d7b507e18c053f8aae25ac1cb3f1bf4cb8569a1d
for the ODALA project.
