zabbix监控nginx

1、安装软件以及修改配置文件

首先安装nginx，可以直接yum安装nginx

yum -y install nginx

安装完nginx之后，修改配置文件
vim /etc/nginx/nginx.conf
server内添加如下信息

location /stub_status {
            allow 127.0.0.1;
            stub_status on;
        }

执行如下命令

/usr/sbin/nginx
curl http://127.0.0.1/stub_status

输出如下消息

Active connections: 1 
server accepts handled requests
 33672 33672 33672 
Reading: 0 Writing: 1 Waiting: 0 

2、编写自定义键值

vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf

UserParameter=nginx.status[*],sh /etc/zabbix/zabbix_agentd.d/nginx.sh $1

对应的nginx.sh脚本

HOST="127.0.0.1"
PORT="80"

stub_status=stub_status
function active() {
    /usr/bin/curl -s "http://$HOST:$PORT/${stub_status}/" 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function accepts() {
    /usr/bin/curl -s "http://$HOST:$PORT/${stub_status}/" 2>/dev/null| awk NR==3 | awk '{print $(1)}'

}
function handled() {
    /usr/bin/curl -s "http://$HOST:$PORT/${stub_status}/" 2>/dev/null| awk NR==3 | awk '{print int($2)}'
}
function requests() {
    /usr/bin/curl -s "http://$HOST:$PORT/${stub_status}/" 2>/dev/null| awk NR==3 | awk '{print int($3)}'
}
function reading() {
/usr/bin/curl -s "http://$HOST:$PORT/${stub_status}/" 2>/dev/null| grep 'Reading' | awk '{print int($2)}'
}
function writing() {
    /usr/bin/curl -s "http://$HOST:$PORT/${stub_status}/" 2>/dev/null| grep 'Writing' | awk '{print int($4)}'
}
function waiting() {
    /usr/bin/curl -s "http://$HOST:$PORT/${stub_status}/" 2>/dev/null| grep 'Waiting' | awk '{print int($6)}'
}
function ping() {
/sbin/pidof nginx |wc -l
}

$1

if [ -z $1 ];then
echo $"Usage $0 {active|accepts|handled|requests|reading|writing|waiting}"
exit
fi

pidof命令可以通过yum安装sysvinit-tools-2.88-14.dsf.el7.x86_64
现在，自定义键值已经准备完毕，接下来就是创建监控项

3、导入模块，创建监控项

nginx模块链接 https://www.ixdba.net/zabbix/zabbix-nginx.zip

导入模块之后在对应的主机上添加nignx模块

添加完模块之后会看到如下几个监控项

4、查看监控项

我们可以以一个监控项为例子，查看他是如何工作的

我们可以看到 导入模块内的监控项还是依赖与我们自定义的键值与编写的脚本
所以 最重要的是脚本

对nginx的监控我们先了解到这里，想要了解更多信息，请关注我 持续更新哦

补充，下面给大家提供了对应的python脚本

import sys
import requests
import re

help_msg = """
usage:
     {} [active,accepts,handled,requests,reading,writing,waiting]
""".format(sys.argv[0])

def usage():
    print(help_msg)

if len(sys.argv) < 2:
    usage()
try:
    r = requests.get(url='http://127.0.0.1:80/stub_status/')
   
except Exception as e:
    print(e)
data = {}
lists = ["active", "accepts", "handled",
         "requests", "reading", "writing", "waiting"]
num = 0
for text in re.findall('\d+', r.text):
    data[lists[num]] = text
    num += 1

for i in sys.argv[1:]:
    if not i in lists:
        usage()
        exit()

for i in sys.argv[1:]:
    print(data[i])
