Logging

java-rest-low-usage-logging.html

The Java REST client uses the same logging library that the Apache Async Http Client uses: Apache Commons Logging, which comes with support for a number of popular logging implementations. The java packages to enable logging for are org.elasticsearch.client for the client itself and org.elasticsearch.client.sniffer for the sniffer.

The request tracer logging can also be enabled to log every request and corresponding response in curl format. That comes handy when debugging, for instance in case a request needs to be manually executed to check whether it still yields the same response as it did. Enable trace logging for the tracer package to have such log lines printed out. Do note that this type of logging is expensive and should not be enabled at all times in production environments, but rather temporarily used only when needed.

Enabling ElasticSearch RestClient response logging when using elastic4s and logback?

elasticsearch-client 默认使用的是 Jdk14Logger(commons-logging.jar)

<!-- 1. exclude `commons-logging` -->
<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-client</artifactId>
    <version>${elasticsearch.version}</version>
    <exclusions>
        <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>

<!-- 2. dependency `jcl-over-slf4j` -->
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jcl-over-slf4j</artifactId>
    <version>${jcl-over-slf4j.version}</version>
</dependency>

然后就可以在logback.xml中配置：

<logger name="org.elasticsearch.client" level="TRACE"/>

remark:

elasticsearch 打印DSL org.elasticsearch.client.RequestLogger#logResponse(...)

FEATURE:

logger打印的request/response 并未格式化
see:

org.elasticsearch.client.RestClient#convertResponse(...)
org.elasticsearch.client.RequestLogger#logRespone(...)
org.elasticsearch.client.RequestLogger#buildTraceRequest(org.apache.http.client.methods.HttpUriRequest, org.apache.http.HttpHost)
org.elasticsearch.client.RequestLogger#buildTraceResponse(org.apache.http.HttpResponse)
