zabbix自动发现 url 以及对http返回状态码监控实现 告警
2019-06-04 18:39:12
目的：批量监控业务URL的返回状态码，通过zabbix监控判断业务好坏。
1、zabbix安装
请查看此永久链接：https://www.cnblogs.com/small-wei/p/10911769.html
2、编写监控脚本
cd /usr/lib/zabbix/externalscripts #本人存放脚本路径，存放路径可以自定义，这个定义文件在zabbix_server.conf中，及zabbix-server服务配置文件。
vim web_site_code_status.sh
#!/bin/bash source /etc/profile >/dev/null 2>&1
WEB_SITE_discovery () {
WEB_SITE=($(grep -v "^#" /usr/local/zabbix/etc/zabbix_script.d/WEBURL.txt))
printf '{\n'
printf '\t"data":[\n'
for((i=0;i<${#WEB_SITE[@]};++i))
{
num=$(echo $((${#WEB_SITE[@]}-1)))
if [[ "$i" != ${num} ]]
then
printf "\t\t{ \n"
printf "\t\t\t\"{#SITENAME}\":\"${WEB_SITE[$i]}\"},\n"
else
printf "\t\t{ \n"
printf "\t\t\t\"{#SITENAME}\":\"${WEB_SITE[$num]}\"}]}\n"
fi
}
} web_site_code () {
#下面注释的是也可以使用域名+端口号
# host=$(echo "$1"|awk -F "/" '{print $3}')
# port=$(echo "$1"|awk -F "/" '{print $3}'|awk -F':' '{print $2}')
# if [[ -z $port ]]
# then
# ntlocal="127.0.0.1"
# else
# ntlocal="127.0.0.1:$port"
# fi
# http_uri=$(echo "$1"|awk -F "/" '{for(i=4;i<=NF;i++) printf "/" $i;printf "\n"}')
# /usr/bin/curl -H "Host:$host" -o /dev/null -s -w %{http_code} $ntlocal${http_uri}
/usr/bin/curl -I "$1" 2> /dev/null | grep 'HTTP' | awk '{print $2}'
} case "$1" in
web_site_discovery)
WEB_SITE_discovery
;;
web_site_code)
web_site_code $2
;;
*)
echo "Usage:$0 {web_site_discovery|web_site_code URL}"
;;
esac
3、创建URL列表
cat /etc/zabbix/zabbix_script.d/web_url_list.txt #这个文件在上面的脚本中定义。
www.baidu.com
www.qq.com
www.redhat.com
https://www.redhat.com/en
https://www/zabbix.com
注意：这里也可以在后面加端口号
4、在zabbix_agentd.conf中添加相关的key
vim /etc/zabbix/zabbix_agentd.conf #客户端配置文件中添加&修改如下内容
UnsafeUserParameters=1 #允许将参数中的所有字符传递给用户定义的参数。
UserParameter=web.site.discovery,/usr/lib/zabbix/externalscripts/web_site_code_status.sh web_site_discovery
UserParameter=web.site.code[*],/usr/lib/zabbix/externalscripts/web_site_code_status.sh web_site_code $1
5、重启zabbix-agent
Linux6：
service zabbix-agent restart
Linux7：
systemctl restart zabbix-agent
6、导入zabbix监控模板文件。
复制如下代码，在本地计算机中创建一个文件：zbx_export_templates.xml （自定义创建）:
<?xml version="1.0" encoding="UTF-8"?>

7、导入模板文件zbx_export_templates.xml
登录zabbix，登录过程跳过；
导入成功后可以看到如下名称的模板：
8、验证查看监控：
至此url监控完毕。
