Aggregate Graphs for Counter-Type Groups Not Working

Environment

• Observium Version: 26.4.14784
• Operating System: Debian 12
• Web Server: Apache HTTP Server (Apache2) 2.4.66
• PHP Version: 8.2.3

Description

Aggregate graphs for groups configured with type: counter do not function correctly. When attempting to view these graphs (stacked or line), the system returns a permission error—even when using an admin account.

Steps to Reproduce

1. Open the Observium web UI
2. Create or configure a group with type: counter using an association ruleset
3. Navigate to the created group in the web UI
4. Go to Aggregate Graphs
5. Select one of the available graph types:
   • multi-counter-stacked, or
   • multi-counter-graph
6. Click on the selected graph

Actual Behavior

• The graphs (multi-counter-stacked / multi-counter-graph) are either not displayed properly or not accessible
• When clicking on them, the following error is shown:

"You have insufficient permissions to view this page."

* This occurs even when logged in as an admin user

Expected Behavior

• The selected aggregate graph should load and display correctly
• No permission error should occur for authorized users (especially admin)

Impact

This issue prevents users from:

• Aggregating counter metrics across multiple devices
• Generating statistical or summary reports
• Performing effective analysis of grouped counter data

This significantly reduces the usefulness of counter-type groups in larger environments.

Additional Notes

• The issue appears specific to counter-type groups
• Other group types (if tested) appear to work correctly
