zabbix配置nginx監(jiān)控的實(shí)現(xiàn)
發(fā)布日期：2022-07-20 19:43 | 文章來源：源碼之家
案例：zabbix 配置 nginx 監(jiān)控
1. 修改配置文件
stub_status 模塊可參考： https://www.jb51.net/article/248979.htm
vim /usr/local/nginx/conf/nginx.conf
location /nginx_status {
stub_status;
}
說明：
nginx_status 自定義字段，訪問地址（例：192.168.169.131/nginx_status）
stub_status 固定參數(shù)
# 重啟 nginx
./nginx reload
瀏覽器訪問狀態(tài)說明： Active connections Nginx正處理的活動鏈接數(shù)個(gè)數(shù)；重要 server Nginx啟動到現(xiàn)在共處理了多少個(gè)連接。 accepts Nginx啟動到現(xiàn)在共成功創(chuàng)建幾次握手。 handled requests Nginx總共處理了幾次請求。 Reading Nginx讀取到客戶端的 Header 信息數(shù)。 Writing Nginx返回給客戶端的 Header 信息數(shù)。 Waiting Nginx已經(jīng)處理完正在等候下一次請求指令的駐留鏈接，開啟。 Keep-alive的情況下，Waiting這個(gè)值等于active-（reading + writing）。 請求丟失數(shù)=(握手?jǐn)?shù)-連接數(shù))可以看出,本次狀態(tài)顯示沒有丟失請求
2. 編寫 nginx 監(jiān)控腳本
#/bin/bash
#Description:Automated monitoring nginx performance and process nginx_status scripts
NGINX_PORT=80
NGINX_COMMAND=$1
nginx_ping(){
/sbin/pidof nginx |wc -l
}
nginx_active(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Active/ {print $NF}'
}
nginx_reading(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Reading/ {print $2}'
}
nginx_writing(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Writing/ {print $4}'
}
nginx_waiting(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Waiting/ {print $6}'
}
nginx_accepts(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk 'NR==3 {print $1}'
}
nginx_handled(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk 'NR==3 {print $2}'
}
nginx_requests(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk 'NR==3 {print $3}'
}
case $NGINX_COMMAND in
ping)
nginx_ping
;;
active)

;;

nginx_writing
;;

;;
*)
echo $"USAGE:$0 {ping|active|reading|writing|waiting|accepts|handled|requests}"
esac
# 修改文件權(quán)限 chmod u+x /etc/zabbix/zabbix_agentd.d/zabbix_nginx.sh
3. 修改 zabbix 配置文件
vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf # 增加 UserParameter=nginx_status[*],/bin/bash /etc/zabbix/zabbix_agentd.d/zabbix_nginx.sh \$1
# 修改完成重啟 zabbix-agent systemctl restart zabbix-agent.service
4. 服務(wù)端驗(yàn)證
[root@zabbix ~]# zabbix_get -s 192.168.169.131 -k nginx_status[active]
5. 添加模塊
模塊名稱：Template Nginx Web Status Monitor（自定義）
可見名稱：NGINX STATUS MONITOR（自定義）
6. 創(chuàng)建應(yīng)用集
名稱：NGINX_STATUS
7. 創(chuàng)建監(jiān)控項(xiàng)
名稱：Nginx_Status_Ping
鍵值：nginx_status[ping]
8. 定義觸發(fā)器
超過50個(gè)并發(fā)連接就執(zhí)行報(bào)警
nginx 服務(wù)down了執(zhí)行報(bào)警
9. 關(guān)聯(lián)主機(jī)
將需要監(jiān)控的主機(jī)添加上此模板
