如何监控 kubernetes 持久卷的磁盘使用情况? [英] How to monitor disk usage of kubernetes persistent volumes?

问题描述

我有 container_fs_usage_bytes 和 prometheus 来监控容器根 fs，但似乎 cAdvisor 中没有其他卷的指标.

I have container_fs_usage_bytes with prometheus to monitor container root fs, but it seems that there is no metrics for other volumes in cAdvisor.

推荐答案

我确认 Kubernetes 1.8 公开了 prometheus 的指标.

I confirmed that Kubernetes 1.8 expose metrics for prometheus.

• 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
