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
<Location /server-status>
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 kBytes: 27
Uptime: 7300
ReqPerSec: .00383562

BusyWorkers: 1
IdleWorkers: 5
Scoreboard: _W____..........................................................................................................................................................................................................................................................
二、脚本编写
#! /bin/bash
#
# Name: zapache
#
# Checks Apache activity.
#
# Version: 1.5
#
zapachever="1.5"
rval=0
value=""
cache_seconds="60"
[ "$TMPDIR" ] || TMPDIR=/tmp
function usage()
{
echo "zapache version: $zapachever"

授权脚本运行权限
[root@oneapm-test scripts]# ll zapache.sh
-rwxr-xr-x. 1 root root 6114 7月 16 13:19 zapache.sh
[root@oneapm-test scripts]# tail -1 ../etc/zabbix_agentd.conf
UserParameter=zapache[*],/usr/local/zabbix/scripts/zapache.sh \$1
在Zabbix服务器监控项测试
[root@Zabbix ~]# /zabbix/bin/zabbix_get -s 172.19.47.225 -p 20050 -k 'zapache[ping]'

[root@Zabbix ~]# /zabbix/bin/zabbix_get -s 172.19.47.225 -p 20050 -k 'zapache[version]'

三、Zabbix导入模板
服务器关联模板：
监控项图形
