意思是說沒有權限訪問agent端口10050，解決方法如下：

將server的agent鏈接IP 127.0.0.1修改為本機IP

重啟服務

# systemctl restart zabbix-server

======================================

Zabbix discoverer processes more than 75% busy

增加Zabbix Server啟動時初始化的進程數量，這樣直接增加了輪詢的負載量，從比例上來講忙的情況就少了

[root@zabbix-server ~]# vim /etc/zabbix/zabbix_server.conf

修改為

StartDiscoverers=5

重啟

[root@zabbix-server ~]# systemctl restart zabbix-server

======================================

zabbix-agent無法啟動錯誤

# tail -20 /var/log/zabbix/zabbix_agentd.log

.........................

zabbix_agentd [1232]: cannot create PID file [/var/run/zabbix/zabbix_agentd.pid]: [2] No such file or directory

zabbix_agentd [3847]: cannot create PID file [/var/run/zabbix/zabbix_agentd.pid]: [2] No such file or directory

zabbix_agentd [1724]: cannot create PID file [/var/run/zabbix/zabbix_agentd.pid]: [13] Permission denied

解決

[root@elkstack ~]# mkdir -p /var/run/zabbix/

[root@elkstack ~]# chown zabbix.zabbix /var/run/zabbix/

[root@elkstack ~]# systemctl restart zabbix-agent.service

zabbix錯誤提示解決
