本文为大家分享了python+influxdb+shell写一个区域网络状况表，供大家参考，具体内容如下

shell脚本部分：

ex：就是ping 各个目的ip10个包，然后获取丢包率和平均延迟时间，在Linux上设置为定时任务，每分钟执行一次。他会把数据写到influxdb服务器上面去，表示hk_vnloss和hk_vn01rtt，字段是loss和rtt，其他各区域的都是类似。

python代码部分：

1、在Django项目的setting里面，配置influxdb数据库连接；

ALLOWED_HOSTS = ['*']

# Application definition

INSTALLED_APPS = [
  'django.contrib.admin',
  'django.contrib.auth',
  'django.contrib.contenttypes',
  'django.contrib.sessions',
  'django.contrib.messages',
  'django.contrib.staticfiles',
  'network_ping.apps.NetworkPingConfig',
  'influxdb_metrics',
]

##influxdb
INFLUXDB_HOST = 'influxdb服务器ip'
INFLUXDB_PORT = 'influxdb port'
INFLUXDB_USER = 'influxdb username'
INFLUXDB_PASSWORD = 'influxdb passwd'
INFLUXDB_DATABASE = 'influxdb database'
INFLUXDB_TIMEOUT = 36000

2、从influxdb数据库查询保存的loss和rtt数据；

from influxdb_metrics.utils import query


def get_loss(tab_name):
  loss_res = query('SELECT * FROM %s ORDER BY time DESC limit 1' % tab_name)
  loss = [res for res in loss_res]
  return loss

3、把数据传到web页面；

##network ping loss
def network_ping(request):
  # vn01 ping vn01
  vnloss01 = get_loss('vnloss')
  # vn01 ping vn02
  vnloss02 = get_loss('vn02loss')
  # vn01 ping th
  thloss = get_loss('thloss')
  # vn01 ping id
  idloss = get_loss('idloss')
  # vn01 ping sg
  sgloss = get_loss('sgloss')
  # vn01 ping tw
  twloss = get_loss('twloss')
  # vn01 ping hk
  hkloss = get_loss('hkloss')
  # vn01 ping sh
  shloss = get_loss('shloss')
  return render(request, 'net_ping.html',
         {'vn01': {
           'vnloss01': vnloss01,
           'vnloss02': vnloss02,
           'thloss': thloss,
           'hkloss': hkloss,
           'idloss': idloss,
           'sgloss': sgloss,
           'twloss': twloss,
           'shloss': shloss
         }，...)

4、在web页面获取进行展示；

<tr>
  <td bgcolor="#f0f8ff" class="titlestyle">VN-01<br/>45.119.241.249</td>
  <td tloss={{ vn01.vnloss01.0.0.loss }}></td>
  <td tloss={{ vn01.vnloss02.0.0.loss }}></td>
  <td tloss={{ vn01.thloss.0.0.loss }}></td>
  <td tloss={{ vn01.idloss.0.0.loss }}></td>
  <td tloss={{ vn01.sgloss.0.0.loss }}></td>
  <td tloss={{ vn01.twloss.0.0.loss }}></td>
  <td tloss={{ vn01.hkloss.0.0.loss }}></td>
  <td tloss={{ vn01.shloss.0.0.loss }}></td>
</tr>

5、js定时刷新页面；

$(function () {
    $("[tloss]").each(function () {
      var loss_res = $(this).attr('tloss');
      if (loss_res < 10) {
        $(this).html('<span class="greentyle"></span><br/>loss: <span bg>' + loss_res);
      } else if (loss_res <= 20) {
        $(this).html('<span class="yellowstyle"></span><br/>loss: ' + loss_res);
      } else {
        $(this).html('<span class="redstyle"></span><br/>loss: ' + loss_res);
      }
    });
    setTimeout("self.location.reload();", 60000);
  })

6、最后的效果展示；
