Exporters

Lunar.dev Exporters allow you to store logs from your processors, enabling better monitoring and analysis of your system’s behavior.

Logs can be exported in two ways:

  • Local File Export – Save logs to a specified location.
  • Cloud Storage Export – Send logs to a Google Cloud Storage (GCP) or Amazon S3 bucket.

Logs are written automatically as they are generated, ensuring that you always have up-to-date insights into your system's performance.

Configuring Exporters​

All export configurations are managed within gateway_config.yaml. Below is an example for each type of configuration:

/etc/lunar-proxy/gateway_config.yaml
exporters:

  file: #Local Exporter
    exporter_id: my_file_exporter
    file_dir: "/var/log/lunar-proxy" # Directory where HAR files will be stored
    file_name: "transaction.log" # Naming pattern for log files

  cloud: #Cloud Exporter
    exporter_id: <exporter id>
    type: "s3"/"gcp" 
    bucket_name: <bucket name>
    region: <region name>

note

You can only have one cloud exporter, meaning either Amazon s3 or GCP. The example above shows how you can configure each one.

Exporter Processor Requirement​

In order for logs to be exported, your flow must use the HAR Exporter Processor. Without this, logs will not be recorded or sent to the specified destination.
