Question

我有一个Filebeat实例，可以将Apache访问日志发送到Logstash。 Logstash管道转换文件并将已处理的字段（ field1，field2＆amp; field3 ）加载到elastic search到索引 indexA 。流程很简单＆amp;工作。这是我的pipeline.conf

input{
    beats{
        port => "5043"
    }
}
filter 
{

    grok 
    {
        patterns_dir => ["/usr/share/logstash/patterns"]
        match =>{   "message" => ["%{IPORHOST:[client_ip]} - %{DATA:[user_name]} \[%{HTTPDATE:[access_time]}\] \"%{WORD:[method]} %{DATA:[url]} HTTP/%{NUMBER:[http_version]}\" %{NUMBER:[response_code]} %{NUMBER:[bytes]}( \"%{DATA:[referrer]}\")?( \"%{DATA:[user_agent]}\")?",
                    "%{IPORHOST:[remote_ip]} - %{DATA:[user_name]} \\[%{HTTPDATE:[time]}\\] \"-\" %{NUMBER:[response_code]} -" ] 
                }
        remove_field => "@version"
        remove_field => "beat"
        remove_field => "input_type"
        remove_field => "source"
        remove_field => "type"
        remove_field => "tags"
        remove_field => "http_version"
        remove_field => "@timestamp"
        remove_field => "message"
    }
    mutate
    {
        add_field => { "field1" => "%{access_time}" }
        add_field => { "field2" => "%{host}" }
        add_field => { "field3" => "%{read_timestamp}" }
    }
}
output {
    elasticsearch{
        hosts => ["localhost:9200"]
        index => "indexA"
    }
}

现在我要做的是添加其他三个字段 field4 和 field5 ，并将它们添加到名为 indexB 的单独索引中。所以最后 indexA 持有 field1 field2 和 field3 ，而 IndexB 持有 field4 ，的字段5

到目前为止，这是修改后的pipeline.conf，它似乎无法正常工作。

input{
    beats{
        port => "5043"
    }
}
filter 
{

    grok 
    {
        patterns_dir => ["/usr/share/logstash/patterns"]
        match =>{   "message" => ["%{IPORHOST:[client_ip]} - %{DATA:[user_name]} \[%{HTTPDATE:[access_time]}\] \"%{WORD:[method]} %{DATA:[url]} HTTP/%{NUMBER:[http_version]}\" %{NUMBER:[response_code]} %{NUMBER:[bytes]}( \"%{DATA:[referrer]}\")?( \"%{DATA:[user_agent]}\")?",
                    "%{IPORHOST:[remote_ip]} - %{DATA:[user_name]} \\[%{HTTPDATE:[time]}\\] \"-\" %{NUMBER:[response_code]} -" ] 
                }
        remove_field => "@version"
        remove_field => "beat"
        remove_field => "input_type"
        remove_field => "type"
        remove_field => "http_version"
        remove_field => "@timestamp"
        remove_field => "message"
    }
    mutate
    {
        add_field => { "field1" => "%{access_time}" }
        add_field => { "field2" => "%{host}" }
        add_field => { "field3" => "%{read_timestamp}" }
    }   
}
output {
    elasticsearch{
        hosts => ["localhost:9200"]
        index => "indexA"
    }
}
filter
{
    mutate
    {
        add_field => { "field4" => "%{source}" }
        add_field => { "field5" => "%{tags}" }
        remove_field => "field1"
        remove_field => "field2"
        remove_field => "field3"
    }
}
output {
    elasticsearch{
        hosts => ["localhost:9200"]
        index => "indexB"
    }
}

有人可以指出我出错的地方或解决方案的替代方案。

您需要使用clone filter复制活动。然后，您可以将所需的字段添加到每个相应的事件中，并将它们放入两个不同的ES索引中：

input{
    beats{
        port => "5043"
    }
}
filter 
{

    grok 
    {
        patterns_dir => ["/usr/share/logstash/patterns"]
        match =>{   "message" => ["%{IPORHOST:[client_ip]} - %{DATA:[user_name]} \[%{HTTPDATE:[access_time]}\] \"%{WORD:[method]} %{DATA:[url]} HTTP/%{NUMBER:[http_version]}\" %{NUMBER:[response_code]} %{NUMBER:[bytes]}( \"%{DATA:[referrer]}\")?( \"%{DATA:[user_agent]}\")?",
                    "%{IPORHOST:[remote_ip]} - %{DATA:[user_name]} \\[%{HTTPDATE:[time]}\\] \"-\" %{NUMBER:[response_code]} -" ] 
                }
        remove_field => "@version"
        remove_field => "beat"
        remove_field => "input_type"
        remove_field => "type"
        remove_field => "http_version"
        remove_field => "@timestamp"
        remove_field => "message"
    }
    clone {
        clones => ["log1", "log2"]
    }
    if [type] == "log1" {
        mutate
        {
            add_field => { "field1" => "%{access_time}" }
            add_field => { "field2" => "%{host}" }
            add_field => { "field3" => "%{read_timestamp}" }
        }
    } else {   
        mutate
        {
            add_field => { "field4" => "%{source}" }
            add_field => { "field5" => "%{tags}" }
        }
    }
}
output {
    if [type] == "log1" {
        elasticsearch{
            hosts => ["localhost:9200"]
            index => "indexA"
        }
    } else {   
        elasticsearch{
            hosts => ["localhost:9200"]
            index => "indexB"
        }
    }
}

Logstash将不同的字段输出到不同的弹性搜索索引
