((node_filesystem_avail_bytes{fstype="xfs"} * 100) / node_filesystem_size_bytes{fstype="xfs"}) - 带宽
irate(node_network_transmit_bytes_total{device=~"eth0"}[5m]) * 8 - metric是采集proc/net/底下的文件得出 https://github.com/prometheus/node_exporter/blob/98a40bd712eaeb1fd3ee60ca37e4091c503d8e1c/collector/netdev_linux.go#L53
