# OpenPay Observability
The bi-temporal append-only ledger is one of OpenPay's architectural
moats: every state transition is a recorded event with both a
*valid-time* (when the event happened in the real world) and a
*transaction-time* (when the ledger learned of it). Inspecting that
moat requires three things: a CLI for ad-hoc queries, OpenTelemetry
traces over the live `Payment<S>` typestate, and a Grafana dashboard
to watch the system from the operations side.
This directory holds the second and third.
## Wiring up
### 1. OpenTelemetry collector
```yaml
# otel-collector.yaml
receivers:
otlp:
protocols:
grpc:
endpoint: 0.0.0.0:4317
http:
endpoint: 0.0.0.0:4318
exporters:
prometheus:
endpoint: 0.0.0.0:9464
service:
pipelines:
metrics:
receivers: [otlp]
exporters: [prometheus]
traces:
receivers: [otlp]
exporters: [prometheus]
```
### 2. OpenPay process
Compile `op-orchestrator` with the `telemetry` feature and set
`OPENPAY_OTLP_ENDPOINT=http://localhost:4317` in the environment.
`op_orchestrator::telemetry::init_telemetry(...)` wires the global
subscriber at startup. Every `Payment<S>` state transition emits a
span with these attributes:
| Attribute | Type | Example |
|-----------------------|---------|-------------------------------|
| `payment.id` | string | `pay_019e30baa...` |
| `payment.state.from` | string | `Authorized` |
| `payment.state.to` | string | `Captured` |
| `payment.rail` | string | `card` · `a2a` · `crypto` |
| `payment.amount.minor`| int | `1299` |
| `payment.amount.currency` | string | `USD` |
### 3. Prometheus + Grafana
Scrape the collector's prometheus exporter at `:9464`. Import
[`grafana-dashboard.json`](grafana-dashboard.json) into Grafana. The
dashboard ships with three template variables: `$rail`, `$currency`,
and the standard `$time_range`.
## Example bi-temporal query
> What was account `acct_019e3...`'s balance on **May 4** as we knew
> it on **May 5**?
```bash
op ledger as-of \
--valid 2026-05-04T00:00:00Z \
--transaction 2026-05-05T00:00:00Z \
--account acct_019e30baa9507793b467ac644636b3e2 \
--human
```
Output (with `--human`):
```
account acct_019e30baa9507793b467ac644636b3e2
valid-time 2026-05-04T00:00:00Z
transaction-time 2026-05-05T00:00:00Z
balance 12_450 minor USD
entries-cited 487
```
Strip `--human` to get the same content as structured JSON for
scripting and reconciliation tooling.
## What the dashboard shows
- **State-transition rate** — transitions per second by `(from, to)`
pair. Spikes on `Authorized → Captured` are the healthy steady state;
`* → Refunded` rate is the dispute / refund pulse.
- **In-flight by state** — current count of payments in each typestate.
Long tails in `Authorized` indicate captures that aren't landing.
- **Refund vs capture ratio** — short-window and long-window. Spikes
beyond a configurable threshold can be wired into the alert manager.
- **Rail split** — card vs A2A vs crypto, by volume and by count.
- **Latency per transition** — p50 / p95 / p99 per state transition,
bucketed by rail.
- **Error rate per state** — counts of `Err(...)` returns from each
state-transition function, bucketed by rail and error class.
## Recompute history
The bi-temporal property of the ledger is the real magic: when an old
reconciliation finds a discrepancy in last week's data, recording the
correction does not rewrite history. It appends a new entry with
*valid-time = last week, transaction-time = now*. The CLI query above
will return the correction when asked from "now" forward and the
original (uncorrected) state when asked from before "now". The
dashboard's data source does the same.
