主机数量多后，Zabbix某些页面无法打开。日志报错：php Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 11 bytes)

我实验过的方式有三种：

安装zabbix-agent

使用SNMP协议

自己写脚本，向console-server发送数据

参考技术A 你好，

调整php配置文件中的可用内存大小，
memory_limit默认值为128M
grep 'memory_limit' /etc/httpd/conf.d/zabbix.conf
php_value memory_limit 512M本回答被提问者采纳

zabbix的api统计zabbix监控的主机数量与主机名

python通过zabbix的api获取监控的主机名和主机数量
