Ingesting Cloudflare Logs and Metrics into Statsig

Run Statsig server SDK evaluations inside Cloudflare Workers, including configuration, request lifecycle, and how to log exposures from the edge.

How Cloudflare Logpush integration works

This guide walks you through setting up the Cloudflare Logpush worker in your Cloudflare account and configuring it to send logs and metrics to Statsig using curl and the Logpush API.

✅ Prerequisites

Configuring Logpush worker

Create an API token.
Ensure the token has logs edit permissions at the account level.
Locate your Cloudflare account ID.
Run the following command and get the job ID:

plaintext

ACCOUNT_ID=<my account id>
CLOUDFLARE_API_TOKEN=<cloudflare token>
curl "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/logpush/jobs" \
  --request POST \
  --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  --json '{
    "name": "statsig-logpush-job",
    "destination_conf": "https://api.statsig.com/v1/log_event/cf_log_drain?header_statsig-api-key=<statsig-secret-key>&header_Content-Type=application%2Fjson",
    "dataset": "workers_trace_events",
    "output_options": {
      "field_names": [],
      "output_type": "ndjson",
      "batch_prefix": "{\"events\":[",
      "batch_suffix": "\n]}\n",
      "record_prefix": "\n  {\"info\":{",
      "record_suffix": "}}",
      "record_delimiter": ",",
      "timestamp_format": "rfc3339"
    }
  }'

In the Cloudflare dashboard, navigate to Analytics & Logs > Logpush and enable the logpush job.

Verify logs on Statsig Console

Explore your logs and metrics at console.statsig.com using the Logs Explorer and Metrics Explorer products under Analytics in the sidebar.
