Node graph issue : nodes are hidden for performance reasons

Grafana Dashboards

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

  • Grafana version: 11

  • Operating system: Kubernetes

  • What are you trying to achieve?
    I am trying to create a network weathermap using the Grafana Node Graph plugin.

  • How are you trying to achieve it?
    I successfully structured the required data frame and fetched it from Prometheus.

  • What happened?

  • When I create only the nodes table, I can see the nodes in the panel.

  • When I create only the edges table, I can see the edges in the panel.

  • However, when I combine both tables, the panel displays a notification:
    “12 nodes are hidden for performance reasons.”

  • The panel gets stuck on “Computing layout” and freezes.

  • What did you expect to happen?
    I expected the Node Graph plugin to work smoothly with Prometheus and render the full network map without issues.

  • Can you copy/paste the configuration(s) that you are having problems with?
    Here is the PromQL query I used:

max by(name, id, color, source, target) (
  label_replace(
    label_replace(
      label_replace(
        ifTable_ifOutOctets{ifAlias=~".*core.*"}, 
        "id", "$1", "ifAlias", "(.*)"
      ),
      "source", "$1", "name", "(.*)"
    ),
    "target", "$1", "ifAlias", "core:([^:]+)"
  )
)

I used Reduce Mode with Series to Rows.

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
    Yes, I received the following message in the Grafana panel:

  • “12 nodes are hidden for performance reasons.”

  • The panel gets stuck on “Computing layout” and becomes unresponsive. “Computing layout”
