Title: Dashboard Panel Shows Cached Data Instead of Updating with New Variable Values

Environment:

  • Grafana version: 11.4.0
  • Docker deployment
  • PostgreSQL datasources
  • Multiple panels with variables

Issue:
When interacting with dashboard panels using variables, the panels show cached data instead of updating with new variable selections. Specifically:

  1. Initial load of panel with Variable A = X shows correct data
  2. Change Variable A to Y
  3. Panel continues showing data from previous variable selection (X)
  4. Manual refresh required to see correct data for new variable selection (Y)

Steps to Reproduce:

  1. Open dashboard with variable-driven panels
  2. Select initial variable value, panel loads correctly
  3. Change variable selection
  4. Panel retains old data instead of updating with new variable
  5. Manual browser refresh required to see updated data

Expected Behavior:

  • Panel should automatically refresh and show new data when variables change
  • No manual refresh should be required to see updated data based on new variable selections

The issue appears after upgrading from Grafana 11.2.5 to newer versions - while dashboard panels refresh correctly with variable changes in 11.2.5, versions 11.3.0 and above require manual refresh to display updated data.

Is there a solution to make panels automatically refresh with variable changes in Grafana versions newer than 11.2.5, similar to how it worked in 11.2.5? I’ve tried adding cacheTimeout, refresh parameters, and query hints, but these haven’t resolved the issue.

I have the same question and I find it happens occasionally. My grafana version is 11.2.0.

OK, where is the source code for this undocumented experimental feature, pls?

No match in the grafana repo: Code search results · GitHub

No match in the whole GitHub: Code search results · GitHub

How it works, when there is no source code? How did you find this feature toggle name, pls?

Could you kindly recommend any alternative solutions to resolve the cache issue please?

Sorry, I don’t answer, when I don’t know answer.

I would like to kindly ask you not to use generative artificial intelligence (a.k.a. GPT, LLM, generative AI, genAI) tools to generate content here. You can see that this is pure AI hallucination in this case. I don’t see this AI hallucination problem with your answers first time.

Users have category, where they can ask AI - Ask AI - Grafana Labs Community Forums

Thanks

so @infofcc3 when you see the term experimental, it is on grafana’s side of things meaning grafana is trying out something early in their development lifecycle

It does not mean you experimenting if something will work or not just by randomly adding it to the ini
