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;
最后:页面是每分钟定时刷新一次,但这个都是当前ping的loss和rtt值,要想看历史的ping情况,可以搭建一个grafana,然后grafana配置数据源为influxdb,就可以查看历史曲线等等,例如:
