将 OpenSearch 采集管道与 Fluent Bit 配合使用

此示例 Fluent Bit 配置文件将日志数据从 Fluent Bit 发送到 OpenSearch 摄取管道。有关摄取日志数据的更多信息，请参阅 Data Prepper 文档中的日志分析。

请注意以下几点：

• host 值必须是管道端点。例如 pipeline-endpoint.us-east-1.osis.amazonaws.com。

• aws_service 值必须为 osis。

• 该aws_role_arn值是 AWS IAM 角色的 ARN，供客户端代入并用于签名版本 4 身份验证。

[INPUT]
  name                  tail
  refresh_interval      5
  path                  /var/log/test.log
  read_from_head        true

[OUTPUT]
  Name http 
  Match *
  Host pipeline-endpoint.us-east-1.osis.amazonaws.com
  Port 443
  URI /log/ingest
  Format json
  aws_auth true
  aws_region us-east-1
  aws_service osis
  aws_role_arn arn:aws:iam::account-id:role/ingestion-role
  Log_Level trace
  tls On

然后，您可以配置如下所示的 OpenSearch 采集管道，该管道以 HTTP 为源：

version: "2"
unaggregated-log-pipeline:
  source:
    http:
      path: "/log/ingest"
  processor:
    - grok:
        match:
          log:
            - "%{TIMESTAMP_ISO8601:timestamp} %{NOTSPACE:network_node} %{NOTSPACE:network_host} %{IPORHOST:source_ip}:%{NUMBER:source_port:int} -> %{IPORHOST:destination_ip}:%{NUMBER:destination_port:int} %{GREEDYDATA:details}"
    - grok:
        match:
          details:
            - "'%{NOTSPACE:http_method} %{NOTSPACE:http_uri}' %{NOTSPACE:protocol}"
            - "TLS%{NOTSPACE:tls_version} %{GREEDYDATA:encryption}"
            - "%{NUMBER:status_code:int} %{NUMBER:response_size:int}"
    - delete_entries:
        with_keys: ["details", "log"]

  sink:
    - opensearch:
        hosts: ["https://search-domain-endpoint.us-east-1.es.amazonaws.com"]
        index: "index_name"
        index_type: custom
        bulk_size: 20
        aws:
          # IAM role that the pipeline assumes to access the domain sink
          sts_role_arn: "arn:aws:iam::account-id:role/pipeline-role"
          region: "us-east-1"
