Prometheus CPU-Usage missing with Lens 2025.10.230725-latest

Lens Support & Troubleshooting
#1

After updating to newest Lens-version (Lens 2025.10.230725-latest) the overview of Pods no longer shows the CPU-Usage.

lens_cpu_usage_notavailable

All other metrics seem to work as before.

In Metrics settings for the clusters i use
Metrics Source: Prometheus
Prometheus: Helm
Prometheus Service Address set explicitly to “namespace/service:port”
active checkbox “Filter empty containers from the Prometheus queries. Try changing this to fix missing metrics.”

Prometheus version used: 3.1.0

Anyone else seeing this behaviour?

I suspect this is related to the change “Fetch Pod CPU/Memory metrics from the selected Metrics Source.”. If you select “Kubernetes Metrics Server” as the Metrics source (temporarily for testing), does that make the CPU metric visible? Assuming Metrics Server is installed to the cluster.

Yes, when selecting “Kubernetes Metrics Server” as the Metrics source the CPU-Usage is visible again:
lens_cpu_usage_metricsserver

#5

So, looks like CPU metrics can’t be fetched from Prometheus. But I can’t tell why that would be. Maybe try using a different query type (Prometheus option), or investigate/debug the data for CPU more.
