Kubernetes Network Metrics Troubleshooting

[calogajac]

I've noticed within the new Kubernetes app when monitoring workloads that I'm consistently not seeing any network utilization metrics on my apps where I know there should be network traffic monitored. The following metrics are what I'm looking for:

dt.kubernetes.pod.network_received_data

dt.kubernetes.pod.network_received_errors

dt.kubernetes.pod.network_received_packets_dropped

dt.kubernetes.pod.network_transmitted_data

dt.kubernetes.pod.network_transmitted_errors

dt.kubernetes.pod.network_transmitted_packets_dropped

I've attempted a number of settings within my configuration to no avail. I am running CloudNativeFullStack in my Kubernetes cluster. Other metrics on these workloads display without issue, but the network metrics never seem to. I have confirmed that my Kubernetes Metrics API should be receiving container network metrics through Prometheus and associated metrics adapters. This seems like it has to be something I'm missing in Dynatrace.

It's worth noting that I am seeing that other monitored Kubernetes clusters display these metrics without issue, implying that the correct Kubernetes settings are applied at a global level.

Does anyone know what metrics Dynatrace is looking for when calling the Kubernetes Metrics API to scrape this information?
