Android app发送日志到Elastic Search

参考：

• logback-android
• logback-elasticsearch-appender

简单记录一下实现过程：

首先添加依赖：

build.gradle：

 // 增加 logback支持，以便于发送log到ES
    implementation 'org.slf4j:slf4j-api:1.7.25'
    implementation 'com.github.tony19:logback-android:2.0.0'
    implementation 'com.internetitem:logback-elasticsearch-appender:1.6'

然后添加logback配置

添加logback.xml 配置文件，到app/src/main/assets下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false" scan="false">
    <appender name="ELASTIC" class="com.internetitem.logback.elasticsearch.ElasticsearchAppender">
        <!-- 下面是我本地的ES server，替换成自己的。如果有用户名密码，用这个形式： http://username:password@yourserver/_bulk -->
        <url>http://192.168.8.167:9000/_bulk</url> 
        <!-- ES 日志名，起个有特点的名字便于在Kibana中过滤 -->
        <index>pay-%date{yyyy-MM-dd}</index>
        <!-- type对应ES中的 _type, 可选，最好有 -->
        <type>android</type>

调用方式

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

///  .. 
private static String TAG = "MyTAG";

// ... 

Logger LOG = LoggerFactory.getLogger(TAG );
LOG.info("Some message");
