Question

如何记录来自elasticsearch的请求？

我设置了elasticsearch/bin/service/elasticsearch.conf：

wrapper.logfile=/var/log/elasticsearch/debug.log

# Log Level for log file output.  (See docs for log levels)
wrapper.logfile.loglevel=DEBUG

但是日志文件只显示：

STATUS | wrapper  | 2012/12/11 13:00:00 | TERM trapped.  Shutting down.
STATUS | wrapper  | 2012/12/11 13:00:02 | <-- Wrapper Stopped

没有关于我的请求的信息......

我使用elasticsearch 0.17.6

Answer 1

elasticsearch 0.17.6中没有可用的请求记录功能。版本0.18.3及更高版本支持logging of slow search operations，可以配置阈值为0ms来记录所有分片的所有搜索请求。在版本0.19.12中，此功能已扩展为index queries as well。

如果您对记录所有HTTP请求感兴趣，elasticsearch-jetty插件支持elasticsearch 0.18.4及更高版本的此功能。

Answer 2

在1.7.3中

配置/ elasticsearch.yml

index.search.slowlog.threshold.query.debug: 0s
index.search.slowlog.threshold.fetch.debug: 0s
index.indexing.slowlog.threshold.index.debug: 0s

和

配置/ logging.yml

  index.search.slowlog: DEBUG, index_search_slow_log_file
  index.indexing.slowlog: DEBUG, index_indexing_slow_log_file

additivity:
  index.search.slowlog: true
  index.indexing.slowlog: true

Answer 3

在Elasticsearch 5.x及更高版本中配置日志记录的首选方法是使用API：

## Elasticsearch slow log
curl -X "PUT" "http://localhost:9200/test_resumes/_settings?preserve_existing=true" \
     -H 'Content-Type: application/json; charset=utf-8' \
     -d $'{
  "index": {
    "search.slowlog.threshold.query.trace": "0ms",
    "search.slowlog.threshold.fetch.trace": "0ms",
    "search.slowlog.level": "trace"
  }
}'

记录elasticsearch请求
