zabbix 3.4.4监控apache

一、Apache开启状态页面

[root@oneapm-test scripts]# httpd -v

Server version: Apache/2.4.6 (CentOS)

Server built: Apr 20 2018 18:10:38

[root@oneapm-test scripts]# cat /etc/httpd/conf/httpd.conf //httpd.conf文件增加如下内容

setHandler server-status

Require all granted

</Location>

ExtendedStatus On

[root@oneapm-test scripts]# systemctl restart httpd //重启httpd服务

访问apache状态页面

[root@oneapm-test scripts]# curl http://localhost:82/server-status?auto

Total Accesses: 28

Total kBytes: 27

Uptime: 7300

ReqPerSec: .00383562

BytesPerSec: 3.7874

BytesPerReq: 987.429

BusyWorkers: 1

IdleWorkers: 5

Scoreboard: _W____..........................................................................................................................................................................................................................................................

二、脚本编写

#! /bin/bash

#

# Name: zapache

#

# Checks Apache activity.

#

# Version: 1.5

#

zapachever="1.5"
