zabbix3.2使用fping批量监控ip的连通性

Posted 2021-01-06 reblue520

1.在zabbix-agent端安装fping

wget http://www.fping.org/dist/fping-3.16.tar.gz

tar zxvf fping-3.16.tar.gz

cd fping-3.16

./configure --prefix=/usr/local/fping/

make && make install


2.编写自动发现脚本

[[email protected]_dlcbs_web01:/usr/local/zabbix_agents_3.2.0/scripts]# cat webip_status.sh 
#!/bin/bash 
# function:monitor tcp connect status from zabbix 
 

web_ip_discovery () { 
WEB_IP=($(cat  /usr/local/zabbix_agents_3.2.0/scripts/webip.txt|grep -v "^#")) 
        printf ‘{
‘ 
        printf ‘	"data":[
‘ 
for((i=0;i<${#WEB_IP[@]};++i)) 
{ 
num=$(echo $((${#WEB_IP[@]}-1))) 
        if [ "$i" != ${num} ]; 
                then 
        printf "		{ 
" 
        printf "			"{#SITENAME}":"${WEB_IP[$i]}"},
" 
                else 
                        printf  "		{ 
" 
                        printf  "			"{#SITENAME}":"${WEB_IP[$num]}"}]}
" 
        fi 
} 
} 
 
web_site_code () { 
/usr/local/fping/sbin/fping $1|grep -c ‘alive‘
} 
 
case "$1" in
web_ip_discovery) 
web_ip_discovery 
;;
web_site_code) 
web_site_code $2
;; 
*) 
 
echo "Usage:$0 {web_ip_discovery|web_site_code [URL]}" 
;; 
esac


3.配置编写
vim /usr/local/zabbix_agents_3.2.0/conf/zabbix_agentd/web_ip_discovery.conf

UserParameter=web.ip.discovery,/usr/local/zabbix_agents_3.2.0/scripts/webip_status.sh web_ip_discovery
UserParameter=web.ip.code[*],/usr/local/zabbix_agents_3.2.0/scripts/webip_status.sh web_site_code $1


[[email protected]_dlcbs_web01:/usr/local/zabbix_agents_3.2.0/scripts]# cat webip.txt 
1.1.1.1
2.2.2.2


触发器：
web.ip.code {#SITENAME} is not alive

# 最近5个取值最大值不为1
{ip_monitor:web.ip.code[{#SITENAME},].max(#5)}<>1


报错处理：
Received value [/usr/local/fping/sbin/fping: can‘t create socket (must run as root?) : Permission denied0] is not suitable for value type [Numeric (unsigned)] and data type [Decimal]


（这里遇到一个问题，在客户端自测脚本是好的，但是到了服务端怎么样都执行不出来fping，因为fping必须由root执行，如果非root会报错，这是权限问题，chmod u+s /usr/local/fping/sbin/fping 就可以解决这个问题。）

[[email protected]_dlcbs_web01:/usr/local/zabbix_agents_3.2.0/scripts]# ll /usr/local/fping/sbin/fping 
-rwxr-xr-x 1 root root 87700 Sep 11 20:54 /usr/local/fping/sbin/fping
[[email protected]_dlcbs_web01:/usr/local/zabbix_agents_3.2.0/scripts]# chmod u+s /usr/local/fping/sbin/fping 
[[email protected]_dlcbs_web01:/usr/local/zabbix_agents_3.2.0/scripts]# ll /usr/local/fping/sbin/fping

# 触发报警的时候由于只是显示IP，这样不能快速知道是哪台服务器出了问题，所以带上主机名，如下

                then 
        printf "		{

        printf "			"{#SITENAME}":"${WEB_IP[$i]}"},
" 
                else 
                        printf  "		{

                        printf  "			"{#SITENAME}":"${WEB_IP[$num]}"}]}
" 
        fi 
} 
} 
 
web_site_code () {
ip=`echo $1|awk -F ‘:‘ ‘{print $1}‘`
#echo $ip
/usr/local/fping/sbin/fping ${ip}|grep -c ‘alive‘
