1、客户端配置

[root@mysql zabbix_agentd.conf.d]# pwd

/usr/local/zabbix-server/etc/zabbix_agentd.conf.d

[root@mysql zabbix_agentd.conf.d]# cat custom_parameters.conf 

UserParameter=masterha_manager,[ `/bin/ps aux | /bin/grep -v grep | /bin/grep -o masterha_manager` == masterha_manager ] &> /dev/null ;echo $?

UserParameter=crond,[ `/bin/ps aux | /bin/grep -v grep | /bin/grep -o crond` == crond ] &> /dev/null ;echo $?

UserParameter=postfix,[ `/bin/ps aux | /bin/grep -v grep | /bin/grep -o postfix` == postfix ] &> /dev/null ;echo $?

UserParameter=error,/usr/local/zabbix-server/error_log.sh

2、检查日志关键字脚本

#!/bin/bash

msg=`tail -n 100 /var/log/secure | grep -iE "error" `

if [ ! -n "$msg" ];then

        echo "OK"

        exit 0

else

        echo "error"

        exit 0

fi
