Zabbix经过Smokeping检测网络质量并告警

（一）Smokeping概述
(1) Smokeping是一款用于网络性能监测的开源监控软件，主要用于对IDC的网络情况，网络质量，稳定性等作检测，经过rrdtool制图方式，图形化地展现网络的时延状况，进而可以清楚的判断出网络的即时通讯状况。php

(2)SmokePing的特色
SmokePing keeps track of your network latency:
Best of breed latency visualisation.（最佳图形展现功能，延时丢包等能够很直观的可视化展示）
Interactive graph explorer.（交互式浏览器图表）
Wide range of latency measurement plugins.（丰富的网络情况测量插件）
Master/Slave System for distributed measurement.（支持主从的分布式部署模式）
Highly configurable alerting system.（自定义报警功能）
Live Latency Charts with the most 'interesting' graphs.（漂亮、免费、开源）
Free and OpenSource Software written in Perl written by Tobi Oetiker, the creator of MRTG and RRDtoolvim

（二）技术概述
使用zabbix经过smokeping来检测网络质量zabbix官方论坛有推荐，能够登录查看下，具体地址以下：https://www.zabbix.com/forum/showthread.php?t=31147
技术关键点有三点：
1，zabbix-trapper：这是一种数据传递方式，不一样于zabbix-agent，这种方式定义的item须要使用zabbix-sender来发送数据给zabbix-server浏览器

2，zabbix-sender须要的参数：bash

-z - 指定zabbix server的IP
-p - 指定zabbix server的端口，默认为10051
-s - 指定目标主机，主机名必须是配置中的hostname而不是visible name，切记
-k - 指定key，咱们定义的trapper的key，这边即是咱们前面定义的trap
-o - 指定要传递的数据

3，使用fping探测各节点丢包率网络

fping的参数：
-b ping包大小
-c ping的次数   
-p ping间隔，单位ms

（三）具体步骤app

（一）在zabbix_server端的配置
1，放开zabbix_server.conf中ExternalScripts的配置并设置为：ExternalScripts=/usr/local/zabbix/externalscripts分布式

[root@localhost externalscripts]# vim /usr/local/zabbix/etc/zabbix_server.conf

### Option: AlertScriptsPath
#       Full path to location of custom alert scripts.
#       Default depends on compilation options.
#
# Mandatory: no
# Default:
# AlertScriptsPath=${datadir}/zabbix/alertscripts
 AlertScriptsPath=/usr/local/zabbix/alertscripts

### Option: ExternalScripts
#       Full path to location of external scripts.
#       Default depends on compilation options.
#
# Mandatory: no
# Default:
# ExternalScripts=${datadir}/zabbix/externalscripts
ExternalScripts=/usr/local/zabbix/externalscripts

2，把zabbix官方推荐的脚本放到ExternalScripts=/usr/local/zabbix/externalscripts/目录下，http://www.mbs-it.pl/inne/zbxsmokeping ide

[root@localhost externalscripts]# cat zbxsmokeping
#!/bin/bash
# Where is your zabbix server
ZBXSERVER=172.19.152.247
# where is fping tool?
FPING=/usr/sbin/fping
# where is zabbix_sender tool?
ZBXSENDER=/usr/bin/zabbix_sender
# Where to send ping
IP=$1
# How many ping to send
COUNT=$2
# What interval between ping [ms]
INTERVAL=$3
# How many bytes in one ping
BYTES=$4
# 'Hostname' of the host which will collect data
HOSTNAME=$5

if [ $# -lt 5 ]
 then
     echo
     echo " Not enough parameters"
     echo " Usage: zbxsmokeping <HOST_IP> <NUMBERS_OF_PINGS> <INTERVAL> <BYTES> <TO_WHICH_HOST_SEND_DATA_IN_ZABBIX>"
     echo " Zabbix External Check Item ex.: zbxsmokeping[{HOST.IP},6,1000,68,{HOST.HOST}]"
  exit 2
fi
# debug
# echo $FPING -b $BYTES -c $COUNT -q -p $INTERVAL $IP 2>&1

OUTPUT=`$FPING -b $BYTES -c $COUNT -q -p $INTERVAL $IP 2>&1 | awk '{print $5,$8}' | tr -d "%|," | tr -s " " "/" | awk -F"/" '{print $3,$4,$5,$6}'`
tab=( $OUTPUT )
# debug
#echo $ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLoos -o ${tab[0]}
#echo $ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLatencyMin -o ${tab[1]}
#echo $ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLatencyMax -o ${tab[3]}
#echo $ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLatencyAvg -o ${tab[2]}

$ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLoos -o ${tab[0]}  -v | grep "Failed 1"
$ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLatencyMin -o ${tab[1]} -v | grep "Failed 1"
$ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLatencyMax -o ${tab[3]} -v | grep "Failed 1"
$ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLatencyAvg -o ${tab[2]} -v | grep "Failed 1"
echo 1

3，给该脚本执行权限，并重启下zabbix_server服务。性能

[root@localhost externalscripts]# chmod +x zbxsmokeping
[root@localhost externalscripts]# ll zbxsmokeping
-rwxr-xr-x 1 root root 1649 Dec 27 17:38 zbxsmokeping
[root@localhost externalscripts]# /etc/init.d/zabbix_server restart

至此zabbix_server端配置完成。插件

（二）在浏览器端配置。
1，把官方推荐的模板导入进来，http://www.mbs-it.pl/inne/zbx_export_templates_smokeping.xml

2，把模板连接到须要检测网络质量的站点上

至此zabbix经过smokeping监控网络质量完成。
