Table visualization not displaying string - OSIsoftPI DB

  • What Grafana version and what operating system are you using?

Hello, I upgraded Grafana dashboard from 7.0.3 to 8.3.6, using OSIsoft-PI data source. I copied previous configuration and database files to 8.3.6 instance and multiple queries no longer display string results.

  • What are you trying to achieve?

Table panels to display string query results instead of 0.

  • How are you trying to achieve it?

I have confirmed the OSIsoft table has the correct data and created overrides (Unit → String) for the fields that are the issue with no luck. Any insights would be greatly appreciated!

Hello :wave: and welcome to the forum, @karinaquevedorodrigu

first I would inspect your panel’s raw request and response. I would see if the strings are sent in the response or not.

Then I would probably file an issue in the repo for that third-party datasource. Looks like the last release was ~18 months ago:

Hi Matt,

Thank you so much for your response. The strings are being captured in the query editor but still no luck displaying in any panels. I will file an issue in the GitHub repo as advised.
