如何记录或打印被调用的python elasticsearch-dsl查询 [英] how to log or print python elasticsearch-dsl query that gets invoked

问题描述

我正在使用 elasticsearch-dsl 将我的python应用程序查询弹性搜索。 / p>

要调试由elasticsearch-dsl库生成的查询，我无法记录或打印弹性搜索的最终查询。

例如，像这样查看请求正文发送到弹性搜索：

  {
query：{
query_string：{
query：Dav *，
fields：[name，short_code]，
analyze_wildcard：true 
} 
} 
} 
  

试图将弹性搜索日志级别提升到TRACE。即使如此，无法看到执行的查询。

解决方案

看看我的博客文章这里，索引级别的Slowlog设置部分。基本上，您可以使用slowlog在单独的日志文件中打印Elasticsearch生成查询。我建议使用非常低的阈值来查看所有查询。

例如，对于特定索引，

  PUT / test_index / _settings 
 {
index：{
 slowlog.level：trace，
search.slowlog.threshold.query.trace：1ms
} 
} 
  / pre> 
 
 
或
  PUT / _settings 
 { 
index：{
search.slowlog.level：trace，
search.slowlog.threshold.query.trace：1ms
} 
} 
  
作为所有索引的集群范围设置。
 
 
 
查询将被记录在您的 / logs 位置，一个名为 [CLUSTER_NAME] _index_search_slowlog.log的文件。
 
I am using elasticsearch-dsl for my python application to query elastic search.

To debug what query is actually getting generated by elasticsearch-dsl library, I am unable to log or print the final query that goes to elasticsearch.

For example, like to see the request body sent to elasticsearch like this :
{
    "query": {
        "query_string": {
           "query": "Dav*",
           "fields": ["name", "short_code"],
           "analyze_wildcard": true
        }
    }
}
Tried to bring the elasticsearch log level to TRACE. Even then, unable to see the queries that got executed.
解决方案
Take a look at my blog post here, "Slowlog settings at index level" section. Basically, you can use slowlog to print in a separate log file Elasticsearch generates, the queries. I suggest using a very low threshold to be able to see all the queries.

For example, something like this, for a specific index:
PUT /test_index/_settings
{
  "index": {
    "search.slowlog.level": "trace",
    "search.slowlog.threshold.query.trace": "1ms"
  }
}
Or
PUT /_settings
{
  "index": {
    "search.slowlog.level": "trace",
    "search.slowlog.threshold.query.trace": "1ms"
  }
}
as a cluster-wide setting, for all the indices.

And the queries will be logged in your /logs location, a file called [CLUSTER_NAME]_index_search_slowlog.log.
