zabbix_agentd.log裏面有出現host [] not found錯誤的解決

查看zabbix_agentd.log時出現下列錯誤
[[email protected] ~]# tail /var/log/zabbix/zabbix_agentd.log
1266:20140523:063554.157 no active checks on server [127.0.0.1:10051]: host [zabbix.linuxidc.com] not found
出現該錯誤的原因是一般是zabbix_agentd.conf裏面的Hostname和前端zabbix web裏面的配置不一樣所造成的，即在zabbix web頁面Monitoring->Configuration->Hosts 頁面的Name和zabbix_agentd.conf裏面的Hostname要一樣。
解決方法：
1.查看zabbix_agentd.conf文件中的Hostname
[root@bjsd-zabbix-x86v-app01 ~]# cat /etc/zabbix/zabbix_agentd.conf | grep Hostname
### Option: Hostname
# Value is acquired from HostnameItem if undefined.
# Hostname=
Hostname=zabbix.linuxidc.com
### Option: HostnameItem
# Item used for generating Hostname if it is undefined. Ignored if Hostname is defined.
# HostnameItem=system.hostname
# Aliases can be used in HostMetadataItem but not in HostnameItem parameters.
2.在zabbix web頁面Monitoring->Configuration->Hosts 頁面更改Host name和zabbix_agentd.conf裏面的Hostname一樣。
3.重新啓動zabbix-agent服務
[root@zabbix ~]# service zabbix-agent restart
Shutting down Zabbix agent: [ OK ]
Starting Zabbix agent: [ OK ]
4.再次查看日誌文件
[root@bjsd-zabbix-x86v-app01 ~]# tail /var/log/zabbix/zabbix_agentd.log
