The Tallyman usage publisher (`enterprise/coderd/usage/publisher.go`)
had no metrics; failures were only visible in logs and the
`usage_events.failure_message` column.
This adds five metrics under `coderd_usage_events_*`:
| Metric | Type | Meaning |
|---|---|---|
| `publish_results_total{result, event_type}` | counter | Per-event
outcomes from real Tallyman responses (`accepted`,
`rejected_temporarily`, `rejected_permanently`; events missing from the
response count as temporary) |
| `publish_send_errors_total` | counter | Ingest requests that failed
entirely (HTTP error, non-200, decode error), one per request |
| `pending` | gauge | Unpublished events still inside the 30-day
publishing window |
| `pending_oldest_age_seconds` | gauge | Age of the oldest pending event
(0 when none) |
| `expired` | gauge | Unpublished events older than 30 days that will
never be published |
Send errors and per-event results never double-count: when a request
fails, the publisher fakes an all-temporarily-rejected response for the
DB update, but only `publish_send_errors_total` increments, so
`publish_results_total` reflects only real Tallyman verdicts.
The gauges are backed by a new read-only `GetUsageEventsStats` query
(authorized as `ActionRead` on `ResourceUsageEvent`) and refreshed from
the publish loop after each attempt, so they update roughly every 17
minutes.
Metrics are created with `promauto.With(reg)` where the registerer
defaults to nil, so existing callers and tests need no changes;
`enterprise/cli/server.go` wires in the deployment's
`PrometheusRegistry` via the new `PublisherWithPrometheusRegisterer`
option.

Coder is a self-hosted platform for cloud development environments and AI coding agents. Workspaces are defined with Terraform, connected through a secure Wireguard® tunnel, and automatically shut down when not used. Coder Agents runs a native AI coding agent whose loop executes in the control plane on your infrastructure, with no API keys in workspaces.
- Define cloud development environments in Terraform
- EC2 VMs, Kubernetes Pods, Docker Containers, etc.
- Automatically shutdown idle resources to save on costs
- Onboard developers in seconds instead of days
- Delegate coding work to AI agents on your infrastructure
- Bring any model (Anthropic, OpenAI, Google, Bedrock, self-hosted)
- No LLM credentials in workspaces, user identity on every action
- Centralized model governance, cost tracking, and audit logging
Quickstart
Check out our install guides for other methods and a complete tutorial.
Try Coder with the install script on Linux and macOS, or grab the latest binary or installer from GitHub Releases on Windows:
curl -L https://coder.com/install.sh | sh
Start the server and open http://localhost:3000 to create your initial user, create a Docker template, and provision your first workspace:
coder server
For a production deployment, add a PostgreSQL database (version 13 or later) and an external access URL, and see our validated architectures for sizing and infrastructure guidance:
coder server --postgres-url <url> --access-url <url>
Without these flags, Coder uses a built-in database and sets up a *.try.coder.app access URL for evaluation. Use coder --help for the full list of flags and environment variables.
