+
+## Configuration
+### Example：
+
+Create a new configuration file in the config directory and name it

+
+The specific configuration is as follows:
+
+ output {
+ doris {
+ http_hosts => [ "http://fehost:8030"; ]
+ user => user_name
+ password => password
+ db => "db_name"

+## Start Up
+Run the command to start the doris output plugin:
+
+`{logstash-home}/bin/logstash -f {logstash-home}/config/logstash-doris.conf
--config.reload.automatic`
+
+
+
+
+## Complete usage example
+### 1. Compile doris-output-plugin
+1> Download the ruby compressed package and go to [ruby official
website](https://www.ruby-lang.org/en/downloads/) to download it. The version
2.7.1 used here
+
+2> Compile and install, configure ruby environment variables
+
+3> Go to the doris source extension/logstash/ directory and execute
+
+`gem build logstash-output-doris.gemspec`
+
+Get the file logstash-output-doris-0.1.0.gem, and the compilation is complete
+
+### 2. Install and configure filebeat (here use filebeat as input)
+
+1> [es official website](https://www.elastic.co/) Download the filebeat tar
compression package and decompress it
+
+2> Enter the filebeat directory and modify the configuration file filebeat.yml
as follows:
+
+ filebeat.inputs:
+ - type: log
+ paths:
+ - /tmp/doris.data
+ output.logstash:
+ hosts: ["localhost:5044"]
+
+/tmp/doris.data is the doris data path
+
+3> Start filebeat：
+
+`./filebeat -e -c filebeat.yml -d "publish"`
+
+
+### 3.Install logstash and doris-out-plugin
+1> [es official website](https://www.elastic.co/) Download the logstash tar
compressed package and decompress it
+
+2> Copy the logstash-output-doris-0.1.0.gem obtained in step 1 to the logstash
installation directory
+
+3> execute
+
+`./bin/logstash-plugin install logstash-output-doris-0.1.0.gem`
+
+Install the plugin
+
+4> Create a new configuration file logstash-doris.conf in the config directory
as follows:
+
+ input {
+ beats {
+ port => "5044"
+ }
+ }
+
+ output {
+ doris {
+ http_hosts => [ "http://127.0.0.1:8030"; ]
+ user => doris
+ password => doris
+ db => "logstash_output_test"
+ table => "output"
+ label_prefix => "doris"
+ column_separator => ","
+ columns => "a,b,c,d,e"
+ }
+ }
+
+The configuration here needs to be configured according to the configuration
instructions
+
+5> Start logstash：
+
+./bin/logstash -f ./config/logstash-doris.conf --config.reload.automatic
+
+### 4.Test Load
+
+Add write data to /tmp/doris.data
+
+`echo a,b,c,d,e >> /tmp/doris.data`
+
+Observe the logstash log. If the status of the returned response is Success,
the import was successful. At this time, you can view the imported data in the
logstash_output_test.output table

+## 完整使用示例
+### 1.编译doris-output-plugin
+1>
下载ruby压缩包，自行到[ruby官网](https://www.ruby-lang.org/en/downloads/)下载，这里使用的2.7.1版本
+
+2> 编译安装，配置ruby的环境变量
+
+3> 到doris源码 extension/logstash/ 目录下，执行
+
+`gem build logstash-output-doris.gemspec`
+
+得到文件 logstash-output-doris-0.1.0.gem，至此编译完成
+
+### 2.安装配置filebeat(此处使用filebeat作为input)
+
+1> [es官网](https://www.elastic.co/)下载 filebeat tar压缩包并解压
+
+2> 进入filebeat目录下，修改配置文件 filebeat.yml 如下：
+
+ filebeat.inputs:
+ - type: log
+ paths:
+ - /tmp/doris.data
+ output.logstash:
+ hosts: ["localhost:5044"]
+
+/tmp/doris.data 为doris数据路径
+
+3> 启动filebeat：
+
+`./filebeat -e -c filebeat.yml -d "publish"`
+
+
+### 3.安装logstash及doris-out-plugin
+1> [es官网](https://www.elastic.co/)下载 logstash tar压缩包并解压
+
+2> 将步骤1中得到的 logstash-output-doris-0.1.0.gem copy到logstash安装目录下
+
+3> 执行
+
+`./bin/logstash-plugin install logstash-output-doris-0.1.0.gem`
+
+安装插件
+
+4> 在config 目录下新建配置文件 logstash-doris.conf 内容如下：
+
+ input {
+ beats {
+ port => "5044"
+ }
+ }
+
+ output {
+ doris {
+ http_hosts => [ "http://127.0.0.1:8030"; ]
+ user => doris
+ password => doris
+ db => "logstash_output_test"
+ table => "output"
+ label_prefix => "doris"
+ column_separator => ","
+ columns => "a,b,c,d,e"
+ }
+ }
+
+这里的配置需按照配置说明自行配置
+
+5> 启动logstash：
+
+./bin/logstash -f ./config/logstash-doris.conf --config.reload.automatic
+
+### 4.测试功能
+
+向/tmp/doris.data追加写入数据
+
+`echo a,b,c,d,e >> /tmp/doris.data`
+
+观察logstash日志，若返回response的Status为 Success，则导入成功，此时可在
logstash_output_test.output 表中查看已导入的数据
