Zabbix: cannot send list of active checks to "127.0.0.1": host "Zabbix server" not monitored

Zabbix: cannot send list of active checks to "127.0.0.1": host "Zabbix server" not monitored

（1）问题现象：查看日志文件发现大量的日志：cannot send list of active checks to "127.0.0.1": host "Zabbix server" not monitored

[root@localhost zabbix]# pwd
/var/log/zabbix
[root@localhost zabbix]#
[root@localhost zabbix]#
[root@localhost zabbix]# ls
zabbix_agentd.log  zabbix_agentd.log-20240922  zabbix_server.log  zabbix_server.log-20240922
[root@localhost zabbix]# cat zabbix_server.log

[root@localhost etc]# cat /var/log/zabbix/zabbix_server.log

（2）网上有人说的原因是web界面下的监测>主机的名称与/etc/zabbix/zabbix_agentd.conf的hostname不一致。

[root@localhost etc]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
[root@localhost etc]#
[root@localhost etc]# cat /etc/hostname
localhost.localdomain
[root@localhost etc]#

[root@localhost etc]# cat /etc/zabbix/zabbix_agentd.conf

Server=127.0.0.1
ServerActive=127.0.0.1
Hostname=Zabbix server

(3)解决

[root@localhost etc]# cat /etc/hosts
192.168.125.201   Zabbix server
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
[root@localhost etc]#
[root@localhost etc]# cat /etc/hostname
Zabbix server
[root@localhost etc]#

[root@localhost etc]# cat /var/log/zabbix/zabbix_server.log

Server=192.168.125.201
ServerActive=192.168.125.201
Hostname=Zabbix server

[root@localhost zabbix]# ls
zabbix_agentd.log  zabbix_agentd.log-20240922  zabbix_server.log  zabbix_server.log-20240922
[root@localhost zabbix]#
[root@localhost zabbix]# mv zabbix_server.log zabbix_server.log-20240927cjh
[root@localhost zabbix]# ls
zabbix_agentd.log  zabbix_agentd.log-20240922  zabbix_server.log  zabbix_server.log-20240922  zabbix_server.log-20240927cjh
[root@localhost zabbix]#
[root@localhost zabbix]#
[root@localhost zabbix]# cat zabbix_server.log
  2298:20240927:024039.128 cannot send list of active checks to "127.0.0.1": host "Zabbix server" not monitored
  2299:20240927:024044.129 cannot send list of active checks to "127.0.0.1": host "Zabbix server" not monitored
  2295:20240927:024049.130 cannot send list of active checks to "127.0.0.1": host "Zabbix server" not monitored
  2297:20240927:024054.130 cannot send list of active checks to "127.0.0.1": host "Zabbix server" not monitored
[root@localhost zabbix]#
[root@localhost zabbix]#
[root@localhost zabbix]# reboot

（4）重启服务器后，还是有这样的日志：

[root@Zabbixserver zabbix]# cat zabbix_server.log
  2290:20240927:024456.743 cannot send list of active checks to "192.168.125.201": host "Zabbix server" not monitored
[root@Zabbixserver zabbix]#

（5）在web界面上先启用对zabbix的监控吧。

（6）结果

后面再没有这样的日志产生了（cannot send list of active checks to "192.168.125.201": host "Zabbix server" not monitored）。
