【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：

[root@Centos ~]# 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}'
[root@Centos ~]#
[root@Centos ~]# cat /etc/zabbix/scripts/WEB.txt
www.baidu.com
www.qq.com
www.51cto.com
[root@Centos ~]#
[root@Centos ~]# zabbix_get -s 192.168.31.160 -k web.site_discovery

[root@Centos ~]# zabbix_get -s 192.168.31.160 -k web.site_code[www.baidu.com]
200
[root@Centos ~]#

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):














脚本返回的值必须是json格式的
