zabbix More than 100 items having missing data

2023-02-28

zabbix告警：

More than 100 items having missing data for more than 10 minutes

原因：

server端與proxy端時間不同步
server端分配的緩存不夠
server端分配的線程不夠
server端負載比較大{CPU,IO,MEM}

zabbix_server有沒有出現告警

Zabbix poller processes more than 75% busy

修改配置文件增大線程數和緩存

zabbix_server.conf
