1. 需求是这样的
一台机器上有两种不同类型的日志数据，且是按天存储的。目录结构是这样的：
--/data/log
--/access_log
--190101.txt
--190102.txt
...
--/click_log
--190101.txt
--190102.txt
...
access_log每行是一个JSON字符串，长得像这样：
xxxxxxxxxx
{
"url": "index",
"server": {
...
},
"timestamp": 1551369609,
"ip": "188.138.188.34",
"session_id": "l9tooea23s6mjlid1q01svmc80",
"method": "GET",
"request_id": "a7ce6bc3e6c39e65eb5d11c979956acf"
}
click_log每行也是一个JSON字符串，长得像这样：
xxxxxxxxxx
{
"click_id": "474b927e12731128579b8100f4f8918b",
"click_obj": [
...
],
"data": {
...
}
}
需求比较简单，提供一个可查功能就可以了：
- 针对access_log，需要解析其中timestamp，方便按时间筛选日志；
- access_log和click_log都需要解析JSON；
2. 调研与实施
在百度一搜，就是ELK，社区又比较火，索性就直接上吧。
2.1 搭建ES集群
比较简单，照着官网来即可，不想英文的，就百度吧，前人已经出了很多案例了。列几个比较好的参考吧： http://jiangew.me/es-deploy-proxy/ https://www.cnblogs.com/leeSmall/p/9189078.html https://www.cnblogs.com/leeSmall/p/9220535.html 我搭建的集群是6节点的，配置如下：
xxxxxxxxxx
cluster.name: myname
node.name: 192-168-0-106
node.master: false
node.data: false
path.data: /data/es/data
path.logs: /data/es/log
network.host: 192.168.0.106
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.0.106", "192.168.0.107", "192.168.0.108", "192.168.0.109", "192.168.0.110", "192.168.0.111"]
discovery.zen.minimum_master_nodes: 3
2.2 搭建kibana
直接用192.168.0.106那个节点，下包、解压、改配置，配置如下：
xxxxxxxxxx
server.host: "192.168.0.106"
elasticsearch.hosts: ["http://192.168.0.106:9200"]
2.3 搭建FileBeat
网上说logstash较重，FileBeat比较轻量，想想，我的需求这么简单就从了。 轻量是轻量，但搭建过程，对于新手来说，还是不容易，中间遇到了很多问题，弯路就不提了，只提两个重要的。
2.3.1 如何解析JSON
参考官网这一页：https://www.elastic.co/guide/en/beats/filebeat/6.6/filebeat-input-log.html 就这两行代码：
xxxxxxxxxx
filebeat.inputs:
- type: log
paths:
- /data/log/access_log/* -- 日志路径
json.keys_under_root: true -- 把JSON中key移到根上(日志JSON只是beat上传数据的一项)
json.add_error_key: true -- 解析失败，把错误放出来
2.3.2 ES 的mapping设置与输出设置
xxxxxxxxxx
setup.template.fields: "access_fields.yml"
setup.template.pattern: "access*"
setup.template.name: "access"
output.elasticsearch:
hosts: ["192.168.0.106:9200"]
index: "access_%{[dissect.key4]}"
pipeline: "log_pipeline"
processors:
- add_host_metadata: ~
- add_cloud_metadata: ~
- dissect:
tokenizer: "%{key1}/%{key2}/%{key3}/%{key4}"
field: "source"
target_prefix: "dissect"
A. 没有用默认的fields.yml，在里面加了一个log_time，且要定义成date类型，需要从数据中的timestamp解析出来，用的pipeline。在kibana上的dev tools功能中console，贴入这段代码，并执行。
xxxxxxxxxx
PUT _ingest/pipeline/log_pipeline
{
"description": "log processor",
"processors": [
{
"date": {
"field": "timestamp",
"target_field" : "log_time",
"formats": [
"UNIX"
],
"timezone":"Asia/Shanghai",
"on_failure": [
{
"set": {
"field": "date_processor_error",
"value": "{{ _ingest.on_failure_message }}"
}
}
]
}
}
]
}
B. 由于每天的数据要单独建索引，而且只能从文件名中提取年月日，所以用了dissect processor。
2.3.2 一个filebeat发一类索引，还是发多类索引
我用的后者，不知道会不会有什么问题，从运行来看，没出什么错。
3. 总结
不得不说，ES的文档写得真详细，搭个demo非常快，但要用好，还是有很多值得探索的地方，抽空再研究一下吧。
