Zabbix5.0 LTS 告警：More than 75% used in the configuration cache

Zabbix5.0 LTS自身触发报警，报警内容如下：

More than 75% used in the configuration cache
Less than25% freeinthe configuration cache
More than 95% used in the configuration cacheh

解决方法：上面的提示均是CacheSize配置过小导致的，默认的CacheSize设置是8M，按提示修改zabbix_server.conf配置文件中cache大小配置即可。步骤如下：

1.查找zabbix_server.conf文件位置

[root@localhost ~]# find / -name 'zabbix_server.conf'
/etc/zabbix/zabbix_server.conf

2.修改zabbix_server.conf配置中Cache大小设置

vi /etc/zabbix/zabbix_server.conf

/CacheSize     //搜索CacheSize位置

### Option: CacheSize
#       Size of configuration cache, in bytes.
#       Shared memory size for storing host, item and trigger data.
#
# Mandatory: no
# Range: 128K-64G
# Default:
#CacheSize=8M
CacheSize=512M

3.重启zabbix服务器，使配置生效

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