kubernetes dynamic pvc / monitoring usage

Question

Is there a simple way to get the current attached volume state (think "space left on disk", or the opposite) ? Using stackdriver, this info is not provided. Not to be found neither within the gcloud console. I was wondering if this was accessible besides connecting to the instance and check it manually

Answer 1

检查Prometeus。

此刻此选项可通过Kubernetes获得，但仅适用于1.8版本。 您可以查看here，其中包含有关此功能请求的完整主题以及实现这些功能的the code。

Kubernetes 1.8公开了普罗米修斯的指标。

• kubelet_volume_stats_available_bytes
• kubelet_volume_stats_capacity_bytes
• kubelet_volume_stats_inodes
• kubelet_volume_stats_inodes_free
• kubelet_volume_stats_inodes_used
• kubelet_volume_stats_used_bytes
