1. Collect memory utilization

Total memory on the node_memory_MemTotal_bytes host

Free memory on the node_memory_MemFree_bytes host

Memory on the node_memory_Buffers_bytes buffer cache

Memory in the node_memory_Cached_bytes page cache

Calculate the percentage of memory used

(total memory-(free memory-buffer + cache)) / total memory * 100

Round ((node_memory_MemTotal_bytes- (node_memory_MemFree_bytes+node_memory_Buffers_bytes+node_memory_Cached_bytes)) / node_memory_MemTotal_bytes * 100)

2. Collect cpu

1. Collect cpu utilization: use the function of irate to calculate the instantaneous growth rate per second and instantaneous growth rate of the authentic time series of distance vectors.

Irate (node_cpu_seconds_total {instance= "$ip"} [5m])

2. Average utilization rate of avg

Avg (irate (node_cpu_seconds_total {job= "server", mode= "idle"} [5m])) * 100

3. Average percentage of usage

Avg (irate (node_cpu_seconds_total {job= "server", mode= "idle"} [5m])) * 100

3. Disk utilization

1. Percentage of disk utilization, idle

Free space / total space

Node_filesystem_files_free {mountpoint= "/", device= "/ dev/mapper/centos-root", job= "server"} / node_filesystem_size_bytes {mountpoint= "/", device= "/ dev/mapper/centos-root", job= "server"} * 100

2. Remaining disk utilization

Node_filesystem_files_free {mountpoint= "/", device= "/ dev/mapper/centos-root"} / node_filesystem_size_bytes {mountpoint= "/", device= "/ dev/mapper/centos-root"} * 100

4. Disk io

1. The growth rate of io in five minutes

Irate (node_disk_io_time_seconds_ Total [5m])

2. Average within five minutes

Avg (irate (node_disk_io_time_seconds_ Total [5m])) * 100

3. Percentage of disk io idle

Avg (irate (node_disk_io_time_seconds_ Total [5m])) * 100)

5. Network

1. The growth rate of the network card within five minutes

Node_network_receive_bytes_total {device=~ "ens160 | docker0"} [5m]

2. Average within five minutes

Round (irate (node_network_receive_bytes_total {device=~ "ens160 | docker0"} [5m]) / 1024)
