服务器巡检脚本-python3

项目地址：https://gitee.com/oceanlee007/check

自动获取主机名，CPU核数，总内存。

检测剩余内存，使用内存，15分钟负载。

依据配置的磁盘挂载目录，获取磁盘容量，磁盘使用大小，磁盘可用大小，磁盘使用率

项目部分代码：

def login_by_passwd(server_host, server_port, username, password):
    ssh_client = paramiko.SSHClient()
    # 设置默认接收主机信任的策略，但是可能报告“不信任主机的”异常
    ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    with open('check.log', 'a', encoding="utf-8") as file_log:
        file_log.write(str(datetime.datetime.today()) + ': Connecting host: ' + server_host + '......' + '\n', )
    print(str(datetime.datetime.today()) + ': Connecting host: ' + server_host + '......')
    try:
        ssh_client.connect(hostname=server_host, port=server_port, username=username, password=password)
        print(str(datetime.datetime.today()) + ': Connect host: ' + server_host + ' success')
        with open('check.log', 'a', encoding="utf-8") as file_log:
            file_log.write(str(datetime.datetime.today()) + ': Connect host: ' + server_host + ' success' + '\n')
        paramiko.util.log_to_file('syslogin.log')
    except Exception as msq:
        print(str(datetime.datetime.today()) + f"{msq}")
        with open('check.log', 'a', encoding="utf-8") as file_log:
            file_log.write(str(datetime.datetime.today()) + ': ERROR： ' + server_host + f"{msq}" + '\n')
