我刚刚在 Centos 8 上从源代码安装了 cacti-1.2.12。完成安装后，我总是在选项卡之间切换，cacti 日志显示：

php.ini（仅会话配置）是：
session.save_handler = files
session.save_path = "/apps/php/var/lib/php/session/"
session.use_strict_mode = 1
session.use_cookies = 1
session.use_only_cookies = 1
session.name = PHPSESSID
session.auto_start = 1
session.cookie_lifetime = 0
session.cookie_path = /
session.cookie_domain =
session.cookie_httponly =
session.serialize_handler = php
session.gc_probability = 1
session.gc_divisor = 1000
session.gc_maxlifetime = 1440
session.referer_check =
session.cache_limiter = nocache
session.cache_expire = 180
session.use_trans_sid = 0
session.hash_function = 0
session.hash_bits_per_character = 5
我怎样才能避免这些错误日志泛滥？
谢谢
