Metrics

Overview

Feast Components export metrics that can provide insight into Feast behavior:

• Feast Ingestion Jobs can be configured to push metrics into StatsD

• Prometheus can be configured to scrape metrics from Feast Core and Serving.

See the Metrics Reference for documentation on metrics are exported by Feast.

Pushing Ingestion Metrics to StatsD

Feast Ingestion Job

Feast Ingestion Job can be configured to push Ingestion metrics to a StatsD instance. Metrics export to StatsD for Ingestion Job is configured in Job Controller's application.yml under feast.jobs.metrics

 feast:
   jobs:
    metrics:
      # Enables Statd metrics export if true.
      enabled: true
      type: statsd
      # Host and port of the StatsD instance to export to.
      host: localhost
      port: 9125

Exporting Feast Metrics to Prometheus

Feast Core and Serving

Feast Core and Serving exports metrics to a Prometheus instance via Prometheus scraping its /metrics endpoint. Metrics export to Prometheus for Core and Serving can be configured via their corresponding application.yml

server:
  # Configures the port where metrics are exposed via /metrics for Prometheus to scrape.
  port: 8081

Direct Prometheus to scrape directly from Core and Serving's /metrics endpoint.
