Thanks for reaching out!
Can I ask how your Data Source is configured for the Octopus Deploy plugin?
Would you be able to send over a screenshot of the page, please?
As this will contain the address of your Octopus server, feel free to upload to our secure upload environment here: Support Files.
You should be able to go to Configuration → Data Sources (within Grafana), then select the Octopus Deploy data source.
The API key shouldn’t be visible, this is fine, as long as I can see the URL format you’ve supplied and that the green check with “Data source is working” displays when you click “save and test”.
I just tested with the most recent version of the plugin myself and a local instance and all seems fine - are you using Octopus Cloud or Octopus Server?
Have you tested importing the sample dashboard that we provide to see if this loads correctly? The dashboard can be imported with this URL: Octopus Deployments Overview dashboard for Grafana | Grafana Labs
I’m looking forward to hearing back, hopefully, we can get this resolved for you.
