最近一直在做服務器端性能優化的事, 而監控是性能優化的首要條件.下面是用zabbix監控Nginx安裝的過程:

1.linux下Nginx的安裝

大家可以參考我以前寫的 Nginx安裝配置篇(Session共享)

2. 配置Nginx_status

在${NGINX_HOME}/conf/nginx.conf的server{}中添加以代碼:

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

注: 爲了安全可以添加allow, deny; allow 是允許某個ip或者一個ip段訪問, deny禁止某個ip或者一個ip段訪問;

3. 安裝zabbix_server與zabbix_agent

大家可以去網上找找相關的資料.

4. 配置zabbix_agent: /etc/zabbix/zabbix_agentd.conf文件

Server=zabbix_server的ip
ServerActive=zabbix_server的ip
Hostname=本機ip #不要寫127.0.0.1

5. 添加nginx_status.sh腳本文件

#!/bin/bash

#script to fetch nginx statuses for tribily monitoring systems
# Author: [email protected]
# License: GPLv2
# Set Variables
BKUP_DATE=`/bin/date +%Y%m%d`
LOG="/data/log/zabbix/webstatus.log"
HOST=127.0.0.1
PORT="80"
# Functions to return nginx stats
function active {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
}
function accepts {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| awk NR==3 | awk '{print $1}'
}
function handled {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| awk NR==3 | awk '{print $3}'
}
# Run the requested function
$1

6. 在/etc/zabbix/zabbix_agentd.d/下添加zabbix_nginx的數據收集文件userparameter_nginx.conf

UserParameter=nginx.accepts,/etc/zabbix/scripts/nginx_status.sh accepts
UserParameter=nginx.handled,/etc/zabbix/scripts/nginx_status.sh handled
UserParameter=nginx.requests,/etc/zabbix/scripts/nginx_status.sh requests
UserParameter=nginx.connections.active,/etc/zabbix/scripts/nginx_status.sh active
UserParameter=nginx.connections.reading,/etc/zabbix/scripts/nginx_status.sh reading
UserParameter=nginx.connections.writing,/etc/zabbix/scripts/nginx_status.sh writing
UserParameter=nginx.connections.waiting,/etc/zabbix/scripts/nginx_status.sh waiting

7. 重啓zabbix-agent服務

service zabbix-agent restart

8.測試zabbix-server可以獲取數據

zabbix_get -s nginx服務ip -p 10050 -k "nginx.connections.active"

9. 配置zabbix-server的nginx status模版
