服务器监控之zabbix监控Nginx篇

最近一直在做服务器端性能优化的事, 而监控是性能优化的首要条件.下面是用zabbix监控Nginx安装的过程:

1.linux下Nginx的安装

大家可以参考我以前写的Nginx安装配置篇(Session共享)

2. 配置Nginx_status

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

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

注: 为了安全可以添加allow, deny; allow 是允许某个ip或者一个ip段访问, deny禁止某个ip或者一个ip段访问;

3. 安装zabbix_server与zabbix_agent

大家可以去网上找找相关的资料.

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

Server=zabbix_server的ipServerActive=zabbix_server的ipHostname=本机ip #不要写127.0.0.1

5. 添加nginx_status.sh脚本文件

#!/bin/bash#script to fetch nginx statuses for tribily monitoring systems# Author: krish@toonheart.com# License: GPLv2# Set VariablesBKUP_DATE=`/bin/date +%Y%m%d`LOG="/data/log/zabbix/webstatus.log"HOST=127.0.0.1PORT="80"# Functions to return nginx statsfunction 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的数据收集文件userparameter_nginx.conf

UserParameter=nginx.accepts,/etc/zabbix/scripts/nginx_status.sh acceptsUserParameter=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. 重启zabbix-agent服务

service zabbix-agent restart

8.测试zabbix-server可以获取数据

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

9. 配置zabbix-server的nginx status模版
