Users report transaction timeout problems with the application, but the metric graphs all look within normal levels.
Which type of failure would prevent the engineer from seeing the problem using the captured metrics?
A. Grafana has lost connectivity to Prometheus, which causes graphs to display only the cached data.
B. CPU and memory metrics from Kubernetes nodes are not accurate due to the way that containers share resources.
