zabbix监控Apache

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 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
#

#
# Checks Apache activity.
#
# Version: 1.5
#
 
zapachever="1.5"
rval=0
value=""
cache_seconds="60"
[ "$TMPDIR" ] || TMPDIR=/tmp
 
function usage()
{
	echo "zapache version: $zapachever"
	echo "usage:"

	echo "  $0 [<url>] GracefullyFinishing           - Check Gracefully Finishing Processess."
	echo "  $0 [<url>] IdleCleanupOfWorker           - Check Idle Cleanup of Worker Processess."
	echo "  $0 [<url>] OpenSlotWithNoCurrentProcess  - Check Open Slots with No Current Process."

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
