Problems creating new data source - Bad Gateway

[gschwepp]

Hello,

I have currently the problem that I cannot add an OSIsoft-PI data source to Grafana.

My Dev Environment:

Grafana and the piwebapi are running on the same computer. For this test I configured the piwebapi to also allow anonymous login. PI-AF, PI-DA and webapi are working properly, as I can query the information with my webbrowser.

The problem:

When I add my webapi URL to the accodring field and hit "Save & Test" I get the notification Bad Gateway. None of the settings seem to solve this problem.

Antoher Problem:

As soon as I remove /piwebapi from the URL the notifcation changes to Data source is working. But it is not. The notification stays the same regardless what I change. Even if I add /piwebapi again back to the URL.

Both behaviours seem wrong to me. Do you require more information from me to resolve this issue?

Thanks a lot.

@gschwepp I don't think we ever tried anonymous login. Can you try with Basic authentication and see if that works?

Hi thank you for you quick response,

this is interesting the another problem does not occur anymore. Anyhow the first problem still happens as described. I configured the datasource as following:

The credentials and the url for the webapi are correct. Any suggestions where to look? After a quick google search this seems to be a known issue, however I didn't find a definite answer to this. Do you have any suggestions where to look? Both, the grafana and the piwebapi logs are not too informative at this point.

Thanks.

You can enable debug in the grafana.ini file

Also, please define the PI Server, AF server and AF Default Database

Thank you for your help. I will look into it during the week.
