Is there a DataDog metric to report the space used or remaining in a GCP PersistentVolume. I have found disk use metrics for the container itself, but not for a PersistentVolume.

I am working in GoogleCloudPlatform.

  • you mean this? https://docs.datadoghq.com/agent/kubernetes/data_collected/ --> `kubernetes_state.persistentvolumeclaim.request_storage` ? – Vit Oct 19 '20 at 10:35
  • @Vitalii That reports the PVC spec.resources.requests.storage value. I want to know how much of that value is used/remains. – Darren Kennedy Oct 20 '20 at 15:03

Found the answer:

The metric kubernetes.kubelet.volume.stats.used_bytes will allow you to get the disk usage on PersistentVolumes. This can be achieved using the tag persistentvolumeclaim on this metric.

You can view this metric and tag combination in your account here: https://app.datadoghq.com/metric/summary?filter=kubernetes.kubelet.volume.stats.used_bytes&metric=kubernetes.kubelet.volume.stats.used_bytes

Documentation on this metric can be found here: https://docs.datadoghq.com/agent/kubernetes/data_collected/#kubelet
