Features

Sync observability dashboard

An embedded Laravel sync observability dashboard that gives you a unified production view of sync activity across all clients:

• Push and pull history with timestamps and client IDs
• Request outcomes, mutation counts, snapshots, and durations
• Top models and clients by sync volume
• Conflict and failure rates
• Five-minute health buckets across the last 24 hours

The dashboard is accessible at a configurable route prefix (default: /tether/dashboard) and is protected by standard Laravel middleware.

Request and mutation inspection

Every captured sync request is logged with configurable payload redaction - you can inspect:

• Redacted incoming mutation payloads
• Redacted raw request and response payloads
• Server-side resolution outcome (applied / rejected / conflict)
• Server state before and after mutation processing
• Field-level diff views between captured payloads and stored state
• Per-request execution timing and outcome summary
• Paginated mutation lists for large request batches

This gives you a practical audit trail of what each client pushed, how the server processed it, and what changed.

Conflict management interface

The conflicts view surfaces every detected data conflict:

• Client payload and server state at the time of conflict
• Rejection reason and request context
• Historical conflict patterns per model and per client

Conflicts are recorded whether the default last-write-wins resolver or a custom resolver is used.

Failure and error tracking

Failed sync operations are captured with full context:

• Validation failures with field-level detail
• Rejected mutation reasons
• Request and mutation context for failed syncs

Failure patterns are grouped and surfaced so you can identify systematic issues (e.g. a model that consistently fails for a specific client).

Replay and debug tools

tether/pro-server allows you to:

• Preview each captured push mutation against the current database state.
• Apply a cloned live replay only when enabled in config and explicitly confirmed by the dashboard request.
• Audit the replay relationship between the original captured request and any cloned replay request.

Live replay clones mutation IDs before processing, so the original captured request remains intact and the cloned request can be inspected afterwards.

Sync telemetry

Aggregated performance metrics available in the dashboard and via a metrics API endpoint:

The metrics API is available at GET /tether/dashboard/metrics.
