F5 BIGIP从应用角度位于网络结构的关键咽喉位置,可获取所有应用的流量,针对流量执行L7层处理,即便是TLS加密的流量也可以通过F5进行SSL offload。通过F5可以统一获取所有应用的请求元数据,而不用关心应用是部署在何种系统架构中,这可以大大简化针对不同应用系统进行应用性能分析、日志采集工作。BIGIP TMOS系统提供了多种方法帮助实现统一信息收集,包括: HTTP Request logging profile DNS logging profile Avr iRule HSL System log…

在配置文件里配置f5_external_physical_mappings = default:1.1:False 但是实际创建vlan还是用tagged方式 (F5 VE in openstack),是因为代码里对这个变量又设置了一遍缺省值default:1.1:True,导致外部配置实际没生效。 对于正常连OS外部F5的,一般都会用tagged方式,所以一般没什么问题(如果外部F5方式也要用非tagged vlan,则同样出问题) 解决方法: 最好不要直接修改代码里的缺省值,防止连接外部F5时候需…
