### What happened? Hi All, We are using Grafana v11.0.0 (83b9528bce) in our Grafana - Prometheus - Fluentbit stack. Same version of grafana is used for visualization in our non production and production environments. We have noticed that incorrect values are being shown for pod's memory usage under Dashboards --> Compute Resources By Deployments --> Memory Quota widget for all the deployments in our production environment. Whereas correct values are shown for the same widget in our non-production environment. As part of Initial analysis, we compared the Prometheus query for that widget and it was same query in the both non prod and production environments. Surprisingly , when we use divide by 3 for existing query , correct values are displayed to pod's memory usage in that widget. Request you to check & assist us to understand, troubleshoot and address this issue. Existing Prometheus query : (sum( container_memory_working_set_bytes{cluster="$cluster", namespace="$namespace", container!="", image!=""} * on(namespace,pod) group_left(workload, workload_type) namespace_workload_pod:kube_pod_owner:relabel{cluster="$cluster", namespace="$namespace", workload="$workload", workload_type="$type"} ) by (pod)) Updated prometheus query: (sum( container_memory_working_set_bytes{cluster="$cluster", namespace="$namespace", container!="", image!=""} * on(namespace,pod) group_left(workload, workload_type) namespace_workload_pod:kube_pod_owner:relabel{cluster="$cluster", namespace="$namespace", workload="$workload", workload_type="$type"} ) by (pod))/3 Thanks, Meghraj ### What did you expect to happen? Expectation : To see the correct value of all the deployment's pod memory usage in this widget - Dashboards --> Compute Resources By Deployments --> Memory Quota ### Did this work before? Not sure ### How do we reproduce it? 1.Use Grafana v11.0.0 2. Use prometheus as datasource 3. use fluentbit v3.0.0 to scrape metrics from AWS EKS cluster v1.31.x ### Is the bug…
