Use Observability Pipelines’ Logstash source to receive logs from your Logstash agent. Select and set up this source when you set up a pipeline.

You can also use the Logstash source to send logs to Observability Pipelines using Filebeat.

Prerequisites

Observability Pipelines の Logstash ソースを使用するには、次の情報が必要です。

• 0.0.0.0:8088 などの Logstash アドレス。Observability Pipelines Worker は、このバインドアドレスでアプリケーションからのログを受信します。後で、アプリケーションを設定してログをこのアドレスに送信します。
• フォワーダーがグローバル設定で SSL を有効にしている場合は、適切な TLS 証明書と、秘密鍵を作成する際に使用したパスワード。

Set up the source in the pipeline UI

Select and set up this source when you set up a pipeline. The information below is for the source settings in the pipeline UI.

Optionally, toggle the switch to enable TLS. If you enable TLS, the following certificate and key files are required.
Note: All file paths are made relative to the configuration data directory, which is /var/lib/observability-pipelines-worker/config/ by default. See Advanced Configurations for more information. The file must be owned by the observability-pipelines-worker group and observability-pipelines-worker user, or at least readable by the group or user.

• Server Certificate Path: The path to the certificate file that has been signed by your Certificate Authority (CA) Root File in DER or PEM (X.509).
• CA Certificate Path: The path to the certificate file that is your Certificate Authority (CA) Root File in DER or PEM (X.509).
• Private Key Path: The path to the .key private key file that belongs to your Server Certificate Path in DER or PEM (PKCS #8) format.

Set the environment variables

• Logstash address and port:
  • Observability Pipelines Worker は着信ログメッセージを受信するためにこのアドレス (例: 0.0.0.0:9997) をリッスンします。
  • DD_OP_SOURCE_LOGSTASH_ADDRESS として環境変数に格納されています。

Send logs to the Observability Pipelines Worker over Logstash

To configure Logstash to send logs to the Observability Pipelines Worker, use the following output configuration:

output {
	lumberjack {
		# update these to point to your Observability Pipelines Worker
		hosts => ["127.0.0.1"]
		port => 5044
		ssl_certificate => "/path/to/certificate.crt"
	}
}

Note: Logstash requires SSL to be configured.
