zipkin启动和过期数据删除

启动zipkin

用elasticsearch的方式启动

QUERY_PORT=9411 STORAGE_TYPE=elasticsearch ES_HOSTS=http://localhost:9200 java -jar zipkin.jar

后台启动

QUERY_PORT=9411 STORAGE_TYPE=elasticsearch ES_HOSTS=http://localhost:9200 nohup java -jar zipkin.jar &

启动elasticsearch

后台启动

./elasticsearch -d

查询elasticsearch数据

curl -s 'localhost:9200/zipkin*span-2017-08-11/_search?q=_q:error=500'

curl -s 'localhost:9200/zipkin*span-2020-05-21/_search'

curl -s 'localhost:9200/zipkin*/_search'

查看elasticsearch的所有索引
curl http://localhost:9200/_cat/indices?v

elasticsearch数据定时删除

上线以后数据急速增加，一天大概3000万的文档，造成zipkin查询很慢，有的时候会报错。
解决办法：

1. 定时删除不需要的数据
2. 修改zipkin采样率，改成0.1

删除elasticsearch的数据可以用elasticsearch-curator

1. 安装方法可以网上查找

2. 配置curator的action
   参考https://www.cnblogs.com/cuishuai/p/10009091.html

   actions:
     1:
    action: delete_indices
    description: >-
      Delete indices older than 1 days (based on index name), for test-
      prefixed indices. Ignore the error if the filter does not result in an
      actionable list of indices (ignore_empty_list) and exit cleanly.
    options:
      ignore_empty_list: True
      timeout_override:
      continue_if_exception: False
      disable_action: False
    filters:
    - filtertype: pattern
      kind: prefix
      value: zipkin
      exclude:
    - filtertype: age
      source: name
      direction: older
      timestring: '%Y-%m-%d'
      unit: days
      unit_count: 1
      exclude:

3. curator的执行命令
   curator --config /etc/curator/config_file.yml /etc/curator/action_file.yml

4. 配置linux定时任务

   crontab -e
