Hi.
I am using the self-hosted Grafana v7+. I want to add a data source using the plugin.
I already managed to create the OHSTAT data source but I cannot create the OHDATA data source.
- How can I create the OHDATA data source in the self-hosted Grafana?, I am not using the Grafana that comes along with the oH2 since I wan to use the newest version.
To create the OHDATA I am using http://localhost:8180/api/grafana/ and no user or password. However, I get a 401 error.
2. Is there any username and password that I should use? Which one is it?
Best regards.
If you are using the self-hosted instance of Grafana, the OHDATA source should already be configured.
FYI, the default URL is ../api/grafana with Browser authentication. Using this allows the current user authenticated with openHistorian to also the authenticated user with Grafana – and openHistorian automatically synchronizes user accounts between openHistorian and Grafana.
Unfortunately the Grafana data source screen treats the URL that starts with ../ as an invalid URL, so you can’t save the data source record. The only way I know to enter this properly is through the SQLite database that Grafana uses to cache it’s primary configuration and screen metadata.
The Grafana database that comes with a fresh install of the openHistorian already includes this update.
If you are trying to setup a stand-alone Grafana instance, you might consider adding a database user to Grafana (view-only role is fine) and use that user to authenticate to the openHistorian Grafana API using the URL you show above.
Thanks,

Thank you.
I managed to configure OHSTAT in an external Grafana, on port 3000, using
http://localhost:6356/api/grafana/ and no authentication.
Moreover, I configured OHDAT on the same external Grafana using
http://localhost:8180/api/grafana/ and the same user and password as the Windows Authentication.
Best regards
