cpu stats in linux code example
Example 1: linux check cpu usage
lscpu
cat /proc/cpuinfo
Example 2: check CPU usage on ssh server
import numpy as np
from tqdm import tqdm
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname, username=usr, password=psswrd, port=22)
print('Checking CPU usage on %s...' %hostname)
cpu_usage=[]
for i in tqdm(range(0,60)):
cmd ="mpstat 1 2 | awk 'END{print 100-$NF}'"
stdin, stdout, stderr = ssh.exec_command(cmd)
for line in stdout.readlines():
cpu_usage.append(np.float(line[:-2]))
ssh.close()
