我有一个HTTP请求，经过的路径为
Gateway(kong)-->WebContainer(gunicorn)-->WebApp(flask)我准备以下流向处理我的日志
file --> filebeat --> kafka topic--> filebeat --> elastic pipeline --> elasticsearch
|
| ----------> HBasegrok, 但是就是不支持，不过给了我们两条路，比如你可以用存JSON的日志啊, 或者用pipeline我想要的日志采集就是简简单单，或者说微服务的内聚力。 一条日志采集线就不该和其他业务混合。最好的就是以下这种状态
onefile -> filebeat_config -> kafka_topic -> filebeat_config -> elastic pipepline -> es indexgunicorn日志采集如下的信息
remote ips
%(t)s [%(h)s] [%(m)s] [%(H)s] [%(U)s] [%(q)s] [%(s)s] [%(a)s] [%(D)s] [%({Kong-Request-ID}i)s] [%({X-Forwarded-For}i)s][15/Nov/2019:10:23:37 +0000] [172.31.37.123] [GET] [HTTP/1.1] [/api/v1/_instance/json_schema/Team/list] [a=1] [200] [Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36] [936] [9cbf6a3b-9c3a-4835-a2ef-02e03ee826d7#16] [137.59.103.3, 172.30.17.253, 172.30.18.12]es processing是6.0之后的功能，相当于es之前自带了一个logstash.对于复杂日志有多种processing，
可以使用grok或者dissect.某些情况下dissect更加快一些.
经过kafka，再有filebeat打到ES, 需要删除多余的信息
PUT _ingest/pipeline/gunicorn

}

}这里比较关键的是ES时间格式文档的定义， 如果某些字段我们觉得有必要分词，就是用text。否则使用keyword。这样可以更加
方便的聚合和查询日志数据, 开启_source方便做一些数据统计

在稳定之后应该将日志接受级别调高。info日志不适合做统计，只是除了问题我们可以快速定位问题所在。 异常应该打到info日志中
INFO日志可以使用我建议的格式。我们关心
