The issue seems to be with the Prometheus configuration. Ensure that spec.enableDefaultServiceMonitor is set to true for the operator. Additionally, set monitor.podMonitor.enabled to true to enable monitoring configuration, as it relies on Prometheus CRDs which are not installed by default. If you're using the prometheus-community/kube-prometheus-stack chart, make sure to set prometheus.prometheusSpec.podMonitorSelectorNilUsesHelmValues to false. Also, verify if Prometheus has the correct scraping targets and if there's a PodMonitor in the monitoring namespace. If not, add one when installing RisingWave with Helm.
