zabbix3.2利用自动发现功能对fastcgi模式的php状态进行集中监控
前端nginx虚拟主机引用后端多个php接口，为了方便监控，将后端服务器集中配置在nginx中，具体配置如下：
[root@eus_nginx:]# cat /usr/local/nginx/config/nginx.conf user apache users;
worker_processes ; worker_cpu_affinity ; error_log /data/www/logs/nginx_log/error/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info; pid logs/nginx.pid; events {
use epoll;
worker_connections ;
} http {
include mime.types;
default_type application/octet-stream; log_format main '$remote_addr - - [$time_local] - - "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent" $request_time ';
log_format error '$remote_addr - - [$time_local] - - "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent" $request_time ';
log_format test '[$fastcgi_script_name] [$time_local] $document_root $remote_addr $status $request_time $body_bytes_sent "$request" "$http_referer" $upstream_addr $http_x_real_ip $http_x_forwarded_for $http_user_agent '; log_format timed_combined '$remote_addr - $remote_user [$time_local] '
'"$request" $status $body_bytes_sent '

} #error_page /.html; error_page /50x.html;

}

1.编写自动发现脚本
[root@eus_nginx:/usr/local/zabbix_agents_3.2.0/scripts]# cat back_php_status.sh
#!/bin/bash
# function:monitor php connect status from zabbix web_ip_discovery () {
WEB_IP=($(cat /usr/local/zabbix_agents_3.2.0/scripts/php_backs.txt|grep -v "^#"))
printf '{\n'
printf '\t"data":[\n'
for((i=;i<${#WEB_IP[@]};++i))
{
num=$(echo $((${#WEB_IP[@]}-)))
if [ "$i" != ${num} ];
then
printf "\t\t{ \n"
printf "\t\t\t\"{#SITENAME}\":\"${WEB_IP[$i]}\"},\n"
else
printf "\t\t{ \n"
printf "\t\t\t\"{#SITENAME}\":\"${WEB_IP[$num]}\"}]}\n"
fi
}
} web_site_code () {
ip=`echo $|awk -F ':' '{print $1}'`
#echo $ip
curl -s -k --connect-timeout -m -o /dev/null -w %{http_code} "http://${ip}"
} case "$1" in
web_ip_discovery)
web_ip_discovery
;;
web_site_code)
web_site_code $
;;
*) echo "Usage:$0 {web_ip_discovery|web_site_code [URL]}"
;;
esac
2.需要监控的php连接
[root@eus_nginx:/usr/local/zabbix_agents_3.2.0/scripts]# cat php_backs.txt
127.0.0.1/back02_status:eus_chinasoft_back02
127.0.0.1/back03_status:eus_chinasoft_back03
127.0.0.1/back04_status:eus_chinasoft_back04
127.0.0.1/back05_status:eus_chinasoft_back05
127.0.0.1/back06_status:eus_chinasoft_back06
127.0.0.1/back07_status:eus_chinasoft_back07
172.20.73.207/back09_status:eus_chinasoft_back09
172.20.73.207/back10_status:eus_chinasoft_back10
172.20.73.207/back11_status:eus_chinasoft_back11
172.20.73.207/back12_status:eus_chinasoft_back12
172.20.73.207/back13_status:eus_chinasoft_back13
172.20.73.207/back14_status:eus_chinasoft_back14
3.编写配置文件
# vim /usr/local/zabbix_agents_3.2.0/conf/zabbix_agentd/php_status_ip_discovery.conf
UserParameter=web.ip.discovery,/usr/local/zabbix_agents_3.2.0/scripts/back_php_status.sh web_ip_discovery
UserParameter=web.ip.code[*],/usr/local/zabbix_agents_3.2.0/scripts/back_php_status.sh web_site_code $1
4.zabbix服务端验证
[root@aliyun-american-guigu-zabbix:~]# zabbix_get -s 1.1.1.1 -k 'web.ip.discovery'
{
"data":[
{
"{#SITENAME}":"127.0.0.1/back02_status:eus_chinasoft_back02"},
{
"{#SITENAME}":"127.0.0.1/back03_status:eus_chinasoft_back03"},
{
"{#SITENAME}":"127.0.0.1/back04_status:eus_chinasoft_back04"},
{
"{#SITENAME}":"127.0.0.1/back05_status:eus_chinasoft_back05"},
{
"{#SITENAME}":"127.0.0.1/back06_status:eus_chinasoft_back06"},
{
"{#SITENAME}":"127.0.0.1/back07_status:eus_chinasoft_back07"},
{
"{#SITENAME}":"172.20.73.207/back09_status:eus_chinasoft_back09"},
{
"{#SITENAME}":"172.20.73.207/back10_status:eus_chinasoft_back10"},
{
"{#SITENAME}":"172.20.73.207/back11_status:eus_chinasoft_back11"},
{
"{#SITENAME}":"172.20.73.207/back12_status:eus_chinasoft_back12"},
{
"{#SITENAME}":"172.20.73.207/back13_status:eus_chinasoft_back13"},
{
"{#SITENAME}":"172.20.73.207/back14_status:eus_chinasoft_back14"}]}
[root@aliyun-american-guigu-zabbix:~]# zabbix_get -s 1.1.1.1 -k 'web.ip.code[172.20.73.207/back14_status:eus_chinasoft_back14]'
200
服务端web的配置：
{monitor_back_php_status:web.ip.code[{#SITENAME},].max(#5)}<>200
