ElasticStack：使用FileBeat、Logstash、Elasticsearch、Kibana收集清洗存储查看分析数据

generator_log.py
# -*- encoding:utf-8 -*-
import time
from chinesename import ChineseName
cn = ChineseName()
while True:
    now = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
    message = "{} {}\n".format(now, cn.getName())
    print(message)
    with open("demo.log", "a", encoding="utf-8") as f:
        f.write(message)
    # 每3秒生成一条日志     
    time.sleep(3)

修改配置文件filebeat.yml
可以选择直接将数据传入Elasticsearch，也可以传入Logstash处理
filebeat.prospectors:
- input_type: log
  paths:
# 配置需要收集的文件地址
    - /var/log/*.log 
#-------------------------- Elasticsearch output ------------------------------
# output.elasticsearch:
  # hosts: ["localhost:9200"]
#----------------------------- Logstash output --------------------------------
output.logstash:
  hosts: ["localhost:5044"]
