Metrics

Galexie publishes metrics through an HTTP-based admin endpoint, which makes it easier to monitor its performance. The data is exposed in Prometheus format, enabling easy integration with existing monitoring and alerting systems. The admin port where these metrics are served can be configured by setting the admin_port variable. By default, the admin_port is set to 6061
With this configuration, the URL to access the metrics endpoint will be:
Galexie emits several application-specific metrics to help track the export process:
  • galexie_last_exported_ledger: The sequence number of the most recently exported ledger.
  • galexie_uploader_put_duration_seconds: The time taken to upload objects to the data lake.
  • galexie_uploader_object_size_bytes: Compressed and uncompressed sizes of the objects being uploaded.
  • galexie_upload_queue_length: Number of objects currently queued and waiting to be uploaded.
In addition to these application-specific metrics, Galexie also exports system metrics (e.g., CPU, memory, open file descriptors) and Stellar Core ingestion metrics such as galexie_ingest_ledger_fetch_duration_seconds Use these metrics to build queries that monitor Galexie’s performance and export process. Here are a few examples of useful queries:
  • Export Times: Query galexie_uploader_put_duration_seconds to monitor average upload times.
  • Queue Length: Use galexie_upload_queue_length to view the number of objects waiting to be uploaded.
  • Latest Exported Ledger: Track galexie_last_exported_ledger to ensure that ledger exports are up-to-date.

Logging

Galexie emits logs to stdout and generates a log line for every object being exported to help monitor progress. Example logs:
