Illegal host header , invalid host #80

Open linuxhub opened 5 years ago

linuxhub commented 5 years ago

Illegal host header , invalid host Prometheus many invalid host metrics tag Causes too much influxDB SERIES For example, 

curl http://127.0.0.1 -H 'Host: www.linuxhub.org'
curl http://127.0.0.1 -H 'Host: test'
curl http://127.0.0.1 -H 'Host: xxx'

Record a lot of invalid hosts

产生很多乱七八糟 与 nginx service name 无关 host 到 Prometheus , 如果 Prometheus 远端存储 用了 influxDB 存储数据，时间线数量猛增，直接完爆时序数据库。 * 建议加个host正则过滤配置

在使用Kong，Apisix等支持根据动态路由转发流量时，不可避免的会接收到特别的host
