## Metrics
|
||||
|
||||
Herald optionally exposes a Prometheus metrics endpoint, useful for scraping with an [OpenTelemetry Collector](https://opentelemetry.io/docs/collector/) or any Prometheus-compatible scraper.
|
||||
|
||||
Set `METRICS_BIND_ADDR` (e.g. `0.0.0.0:9100`) to enable it. The metrics are then available at `http://<host>:9100/metrics`.
|
||||
|
||||
### Exposed metrics
|
||||
|
||||
| Metric | Type | Description |
|
||||
|---|---|---|
|
||||
| `herald_webhooks_received_total` | counter | Total webhooks received (label: `event_type`) |
|
||||
| `herald_webhooks_duplicate_total` | counter | Webhooks rejected as duplicates (label: `event_type`) |
|
||||
| `herald_webhooks_channel_full_total` | counter | Webhooks dropped because the bot channel was full (label: `event_type`) |
|
||||
| `herald_bot_tasks_active` | gauge | Bot tasks currently in progress |
|
||||
| `herald_bot_tasks_completed_total` | counter | Bot tasks completed successfully (label: `event_type`) |
|
||||
| `herald_bot_tasks_failed_total` | counter | Bot tasks that failed (label: `event_type`) |
|
||||
| `herald_openrouter_cost_cents_total` | counter | Total OpenRouter cost in cents (divide by 100 for USD) |
