Zabbix監(jiān)控Nginx性能的實現(xiàn)方式

2019-02-15 分類：服務(wù)器技術(shù) 閱讀(934) 評論(0)

nginx和php-fpm一樣內(nèi)建了一個狀態(tài)頁，對于想了解nginx的狀態(tài)以及監(jiān)控nginx非常有用，為了后續(xù)的zabbix監(jiān)控，我們需要先啟用nginx狀態(tài)頁

1. 啟用nginx status配置
在默認(rèn)主機里面加上location或者你希望能訪問到的主機里面。

server {
location /ngx_status
{
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}
}

示例：

upstream lvs_server{
server 10.27.13.215:8555; #hd_lvs_voice01
server 10.26.114.166:8555; #hd_lvs_voice02
server 10.27.62.9:8555; #hd_lvs_voice03
server 10.30.196.175:8555; #hd_lvs_voice04
#server 10.30.196.157:8555; #hd_lvs_voice05
}

server {
listen 8555;
access_log /var/log/nginx/voice_lvs.access.log main;
error_log /var/log/nginx/voice_lvs.error.log;

location / {
proxy_pass http://lvs_server;
}

location /index {
proxy_set_header Host $http_host;
proxy_set_header X-Real-Ip $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Content-Type application/octet-stream;
proxy_pass http://lvs_server;

}
location /ngx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
#deny all;
}

}

2. 重載nginx

# nginx -t
# service nginx reload

3. 打開status頁面

# curl 127.0.0.1:8555/ngx_status
Active connections: 2
server accepts handled requests
3091 3091 3254
Reading: 0 Writing: 1 Waiting: 1

# curl 127.0.0.1:8555/ngx_status
Active connections: 2
server accepts handled requests
3092 3092 3255
Reading: 0 Writing: 1 Waiting: 1

4. nginx status詳解

active connections – 活躍的連接數(shù)量
server accepts handled requests — 總共處理了11989個連接 , 成功創(chuàng)建11989次握手, 總共處理了11991個請求
reading — 讀取客戶端的連接數(shù).
writing — 響應(yīng)數(shù)據(jù)到客戶端的數(shù)量
waiting — 開啟 keep-alive 的情況下,這個值等于 active – (reading+writing), 意思就是 Nginx 已經(jīng)處理完正在等候下一次請求指令的駐留連接.

以上為nginx性能計數(shù)，我們除了監(jiān)控以上數(shù)據(jù)，還需要監(jiān)控nginx進程狀態(tài)，并且配置觸發(fā)器
zabbix客戶端配置

編寫客戶端腳本nginx_status.sh

# 檢測nginx性能

mkdir -p /usr/local/zabbix-agent/scripts
vim /usr/local/zabbix-agent/scripts/nginx_status.sh

#!/bin/bash
HOST=”127.0.0.1″
PORT=”8555″
# 檢測nginx進程是否存在
function ping {
/sbin/pidof nginx | wc -l
}

# 檢測nginx性能

function active {
/usr/bin/curl “http://$HOST:$PORT/ngx_status/” 2>/dev/null| grep ‘Active’ | awk ‘{print $NF}’
}
function reading {
/usr/bin/curl “http://$HOST:$PORT/ngx_status/” 2>/dev/null| grep ‘Reading’ | awk ‘{print $2}’
}
function writing {
/usr/bin/curl “http://$HOST:$PORT/ngx_status/” 2>/dev/null| grep ‘Writing’ | awk ‘{print $4}’
}
function waiting {
/usr/bin/curl “http://$HOST:$PORT/ngx_status/” 2>/dev/null| grep ‘Waiting’ | awk ‘{print $6}’
}
function accepts {
/usr/bin/curl “http://$HOST:$PORT/ngx_status/” 2>/dev/null| awk NR==3 | awk ‘{print $1}’
}
function handled {
/usr/bin/curl “http://$HOST:$PORT/ngx_status/” 2>/dev/null| awk NR==3 | awk ‘{print $2}’
}
function requests {
/usr/bin/curl “http://$HOST:$PORT/ngx_status/” 2>/dev/null| awk NR==3 | awk ‘{print $3}’
}
# 執(zhí)行function
$1

添加腳本執(zhí)行權(quán)限

# chmod +x /usr/local/zabbix-agent/scripts/nginx_status.sh

zabbix客戶端配置
將自定義的UserParameter加入配置文件，然后重啟agentd，如下：

# vim /etc/zabbix/zabbix_agentd.conf

UserParameter=nginx.status[*],/usr/local/zabbix-agent/scripts/nginx_status.sh $1

重啟zabbix-agent
/etc/init.d/zabbix-agent restart

zabbix_get獲取數(shù)據(jù)

此步驟可以跳過，但是最好是測試一下，因為通過此命令我們可以檢測配置是否正確

# zabbix_get -s ip -p 10050 -k ‘nginx.status[accepts]’
3101
# zabbix_get -s ip -p 10050 -k ‘nginx.status[ping]’
1

zabbix web端配置

導(dǎo)入Template App NGINX模板

Link NGINX模板
到了最后一個階段，登陸zabbix管理端，link模板到nginx服務(wù)器：configuration->hosts->點擊nginx所在服務(wù)器->點擊template->Link new templates輸入”Template App NGINX”->Add->最后點擊update
