python获取服务器性能

最近在学习python，首先学习一下性能指标的监控，平时做性能测试都是在服务器上部署测试脚本进行监控，比较麻烦，现在有了这个脚本就可以直接抓取远程的性能指标写到报告中
#!/usr/bin/python
#coding:utf-8
import paramiko,string,time
remote_m = [
    # db server
    ('10.10.10.29', 'zhanghao', '!qaz@wsx3edc'),
    # tomcat
    ('10.10.10.30', 'zhanghao', '!qaz@wsx3edc')
]
def getcpuload(host, user, pwd):
        cmd='uptime |awk \'{print $10 $11 $12}\''
        #cmd='top -n 1'
        ssh = paramiko.sshclient()
        ssh.set_missing_host_key_policy(paramiko.autoaddpolicy())
        ssh.connect(host,22,user, pwd)
        stdin, stdout, stderr = ssh.exec_command(cmd)
        load_info=stdout.readlines()
        erro_info=stderr.readlines()
        erro_message=('erro_messag: %s' %erro_info + '\n')
        sstr1=string.join(load_info)
        #load_info = sstr1[sstr1.index('average')+9:len(sstr1)]
        return sstr1
        ssh.colse()
if __name__ == "__main__":

    report_name = 'report_' + time.strftime('%y%m%d%h%m',time.localtime(time.time())) + '.rpt'
    debug_name = 'default.debug'
    report_file = open('./reports/' + report_name, 'a')
    debugfile = open(debug_name, 'a')
    print 'benchmark start, generate report:' + report_name
    report_file.write('start at ' + time.strftime('%y-%m-%d %h:%m:%s',time.localtime(time.time())) + '\n')

    for m in remote_m:
         print ('%s load: %s' %(m[0], getcpuload(m[0], m[1], m[2])))
         report_file.write('%s load: %s' %(m[0], getcpuload(m[0], m[1], m[2])))

使用shell调用测试结果
#/bin/bash
  python /home/shell/python_log/test.py
  echo "执行成功"
