ElasticSearch默认情况下使用Log4j2来记录日志，日志配置文件的路径为$ES_HOME/config/log4j2.properties，配置方法见Log4j2的官方文档。

参考path-settings，通过指定path.logs，可以指定日志文件的保存路径。

在日志配置文件$ES_HOME/config/log4j2.properties中可以使用的变量，如下：

es.logs.base_path，指的是日志文件的根路径。
es.logs.cluster_name，指的是集群的名称。
es.logs.node_name，指的是节点的名称。

按照log4j2的配置规范，上述变量在日志配置文件log4j2.properties中引用时，使用方法如下：

${sys:es.logs.base_path}
${sys:es.logs.cluster_name}
${sys:es.logs.node_name}

配置日志级别的方法，分为：

运行期配置，修改后即时生效，不需要重启服务。
静态配置，修改后需要重启才能生效。

运行期配置

查看当前配置。

 curl -X GET "https://localhost:9200/_cluster/settings?pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

执行结果如下：

 {
"persistent" : { },
"transient" : { }
}

指定logger.org.elasticsearch.discovery的日志级别为DEBUG。

 curl -X PUT "https://localhost:9200/_cluster/settings?pretty" -H 'Content-Type: application/json' -d'
{
    "persistent": {
        "logger.org.elasticsearch.discovery": "DEBUG"
    }
}
' --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

执行输出如下：

 {
"acknowledged" : true,
"persistent" : {
    "logger" : {
    "org" : {
        "elasticsearch" : {
        "discovery" : "DEBUG"
        }
    }
    }
},
"transient" : { }
}

查看配置结果。

 curl -X GET "https://localhost:9200/_cluster/settings?pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

执行结果如下：

 {
"persistent" : {
    "logger" : {
    "org" : {
        "elasticsearch" : {
        "discovery" : "DEBUG"
        }
    }
    }
},
"transient" : { }
}

恢复logger.org.elasticsearch.discovery的日志级别。

 curl -X PUT "https://localhost:9200/_cluster/settings?pretty" -H 'Content-Type: application/json' -d'
{
"persistent": {
    "logger.org.elasticsearch.discovery": null
}
}
' --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

执行结果如下：

 {
"acknowledged" : true,
"persistent" : { },
"transient" : { }
}

查看当前配置。

 curl -X GET "https://localhost:9200/_cluster/settings?pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

执行结果如下：

 {
"persistent" : { },
"transient" : { }
}

静态配置
修改配置文件elasticsearch.yml，增加如下配置：

 logger.org.elasticsearch.discovery: DEBUG

或者修改日志配置文件log4j2.properties，增加如下配置：

 logger.discovery.name = org.elasticsearch.discovery
logger.discovery.level = debug
