和之前写过的Zabbix 3.2 agentd监控Nginx性能原理差不多，都是通过web引擎输出status信息来进行性能监控，一般情况下我们需要对ReqPerSec、BytesPerSec、BusyWorkers、IdleWorkers四个数据进行关注。
开启Apache Status
Listen 80 <VirtualHost *:80> CustomLog /dev/null common ErrorLog /dev/null <Location "/server-status"> SetHandler server-status Require ip 127.0.0.1 </Location> </VirtualHost> |
我这里生产环境监控的是一台WHM服务器，默认开启apache status，访问地址为http://127.0.0.1:80/whm-server-status?auto，正常情况下应该如下页面内容：
Apache Server Status for 127.0.0.1 (via 127.0.0.1)
Server Version: Apache/2.4.37 (cPanel) OpenSSL/1.0.2p mod_bwlimited/1.4
Server MPM: prefork
Server Built: Oct 29 2018 18:29:24
Current Time: Thursday, 22-Nov-2018 13:48:50 CST
Restart Time: Thursday, 22-Nov-2018 13:48:35 CST
Parent Server Config. Generation: 1
Parent Server MPM Generation: 0
Server uptime: 15 seconds
Server load: 0.05 0.09 0.08
Total accesses: 7 – Total Traffic: 54 kB – Total Duration: 19687
CPU Usage: u.02 s0 cu0 cs0 – .133% CPU load
.467 requests/sec – 3686 B/second – 7.7 kB/request – 2812.43 ms/request
7 requests currently being processed, 4 idle workers……………
创建Apache Status采集脚本
mkdir /usr/local/zabbix/share/scripts vim /usr/local/zabbix/share/scripts/apache_status.sh #!/bin/bash URL="http://127.0.0.1:80/whm-server-status?auto" function ReqPerSec(){ /usr/bin/curl -s $URL |grep ReqPerSec|awk '{print $2}' } function BytesPerSec(){ /usr/bin/curl -s $URL |grep BytesPerSec|awk '{print $2}' } function BusyWorkers(){ /usr/bin/curl -s $URL |grep BusyWorkers|awk '{print $2}' } function IdleWorkers(){ /usr/bin/curl -s $URL |grep IdleWorkers|awk '{print $2}' } function ping(){ /usr/sbin/pidof httpd|wc -l } $1 chmod +x /usr/local/zabbix/share/scripts/apache_status.sh chown zabbix:zabbix /usr/local/zabbix/share/scripts/apache_status.sh vim /usr/local/zabbix/etc/zabbix_agentd.conf #加入 UserParameter=apache.status[*],/usr/local/zabbix/share/scripts/apache_status.sh "$1" /etc/init.d/zabbix_agent restart #特别看下这个带单位的：单位我这里写的Bps，Bytes每秒的意思，但在zabbix中，它会自动帮你换算成KBps。 |
zabbix中导入模板并调用到主机即可
