日志服务器上没日志怎么排查

建议再检查下配置，一般都是配置问题。

防火墙快速日志输出输出方式配置：
\# 开启快速日志输出功能，如将会话管理模块、IPS、AV、安全策略的日志快速输出到日志主机。
system-view
[Device] customlog format session
[Device] customlog format dpi ips
[Device] customlog format dpi anti-virus
[Device] customlog format security-policy
\# 将会话管理模块的日志快速输出到日志主机，其IP地址为1.2.0.1/16。
[Device] customlog host 1.2.0.1 port 1000 export session
\# 开启新建和删除会话时输出日志会话日志信息功能。
[Device] session log flow-begin
[Device] session log flow-end
\# 在GigabitEthernet2/0/1（连接内网的接口）接口下开启会话日志功能，指定输出此接口入方向上的所有IPv4会话日志。
[Device] interface gigabitethernet 2/0/1
[Device-GigabitEthernet2/0/1] session log enable ipv4 inbound

如果是新版本，在WEB页面【系统】-【日志设置】-【基本配置】-【存储空间设置】中确保对应的日志模块开启
