zabbix 监控 nginx性能

首先需要配置ngx_status

vim /etc/nginx/vhost/web.conf
server
{
listen 80;
server_name 192.168.80.62;
index index.php index.html index.htm default.html default.htm default.php;
root /usr/local/nginx/html;
location ~ .*\.(php|php5)?$
{
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include /etc/nginx/fastcgi_params;
}

location ~ ^/(status|ping)$
{
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
}

location /ngx_status { #加上红色部分
stub_status on;
access_log off;
}

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 12h;
}

access_log off;
}

重启nginx

测试如下ok

[root@zabbixserver ~]# curl http://127.0.0.1/ngx_status Active connections: 6
server accepts handled requests
8764 8764 38033
Reading: 0 Writing: 1 Waiting: 5

zabbix客户端配置

编写客户端脚本

vim /usr/local/zabbix/scripts/ngx-status.sh

#!/bin/bash

HOST="127.0.0.1"
PORT="80"

# 检测nginx进程是否存在
function ping {
/sbin/pidof nginx | wc -l
}
# 检测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}'
}
# 执行function
$1

记得加执行权限

zabbi客户端配置

vim /usr/local/zabbix/etc/zabbix_agentd.conf

UserParameter=nginx.status[*],/usr/local/zabbix/scripts/ngx-status.sh $1
killall zabbix_agentd
/usr/local/zabbix/sbin/zabbix_agentd

测试zabbix_get 获取数据

/usr/local/zabbix/bin/zabbix_get -s 192.168.80.62 -k 'nginx.status[accepts]'
/usr/local/zabbix/bin/zabbix_get -s 192.168.80.62 -k 'nginx.status[ping]'

最后zabbix web配置 导入模板即可
