1.磁盤使用率
1.other：((node_filesystem_size_bytes{fstype=~"xfs|ext4",instance="server2"} - node_filesystem_free_bytes{fstype=~"xfs|ext4",instance="server2"}) / node_filesystem_size_bytes{fstype=~"xfs|ext4",instance="server2"}) * 100 3.my: ((node_filesystem_size_bytes{fstype=~"xfs"} - node_filesystem_free_bytes{fstype=~"xfs"}) / node_filesystem_size_bytes{fstype=~"xfs"}) * 100
2.server1的內存使用率(單位為percent)
(1 - (node_memory_MemAvailable_bytes{} / (node_memory_MemTotal_bytes{})))* 100
3.CPU使用率(單位為percent)
1 - avg(irate(node_cpu_seconds_total{mode="idle"}[1m])) by (instance)
4.網絡流出量(單位為bytes/sec)
irate(node_network_transmit_bytes_total{device!~'tap.*|veth.*|br.*|docker.*|virbr*|lo*'}[5m])*8
legend format:{{instance}}_{{device}}_out upload
5.網絡流入量(單位為bytes/sec)
irate(node_network_receive_bytes_total{device!~'tap.*|veth.*|br.*|docker.*|virbr*|lo*'}[5m])*8
legend format: {{instance}}_{{device}}_in download
