When using v0.14.0, I can see the filesystem metrics for that device/mountpoint (seen below). Yet the new version v0.15.0 does not export the same metrics. docker run --log-driver none --name node-exporter --net host --pid host --volume /proc:/host/proc --volume /sys:/host/sy...

要监控磁盘容量,需要用到node_filesystem_*相关的指标,比如要查询节点磁盘空间使用率,则可以同样用总的减去可用的来进行计算,磁盘可用空间使用node_filesystem_avail_bytes指标,但是由于会有一些我们不关心的磁盘信息,所以我们可以使用fstype标签过滤关心的磁盘信息,比如ext4或者xfs格式的磁盘: ...
要查询磁盘空间使用率,则使用查询语句(1 - node_filesystem_avail_bytes{fstype=~"ext4|xfs"} / node_filesystem_size_bytes{fstype=~"ext4|xfs"}) * 100即可: 磁盘空间使用率 这样就可以得到我们关心的磁盘空间使用率了。 磁盘IO 监控 要监控磁盘 IO,就要区分是读的 IO,还是写的 IO,读 IO 使用node_dis...
