【8】、Low Level Discovery发现实现实时监控

环境：Centos 6.6

Zabbix自动发现WEB站点：

[[email protected] ~]# tail -3 /etc/zabbix/zabbix_agentd.conf
UserParameter=web.site_discovery,/etc/zabbix/scripts/discovery_web_site.sh web_site_discovery
UserParameter=web.site_code[*],/etc/zabbix/scripts/discovery_web_site.sh web_site_code $1
UserParameter=memory.free,free -m|grep Mem |awk ‘{print $4}‘

创建web_monitor的模版，Configuration---Templates：

Configuration---Templates(web_status_code_monitor)---discovery---create discovery rule:

Configuration---Templates(web_status_code_monitor)---discovery(1)---Item prototypes (0)---create item prototype:

Configuration---Templates(web_status_code_monitor)---discovery(1)---Trigger prototypes (0)---Create Trigger prototype:

Configuration---Templates(web_status_code_monitor)---discovery(1)---Graph prototypes (0)---Create Graph prototype:

Configuration---Host---Zabbix server---Templates---Add:

Configuration---Host---“Zabbix Server”---Discovery(1):
