Vantmetry

Appearance

Dashboard ​

The Vantmetry dashboard is a web interface for viewing and managing your error data. Log in to access your projects and configure alerts.

Issues ​

The main view shows errors grouped by fingerprint (a hash of the error type, message, and stack trace). Each row displays:

  • Last seen timestamp
  • Error type and message
  • Trend sparkline showing error frequency over time
  • Events total count
  • Sessions count of distinct browser sessions affected
  • Time range: preset ranges (Last Hour, Last 24h, Last 7d, Last 30d) or a custom date picker
  • Severity: filter by ERROR, WARN, INFO, or DEBUG
  • Search: full-text search across error messages and exception types
  • Sort: by Last Seen, First Seen, Events, or Sessions in ascending or descending order

Results are paginated at 50 per page.

Issue details ​

Click any issue to see a detailed view with:

  • Total events and affected sessions counts
  • Timeline of variants: each unique combination of message, URL, and stack trace
  • Stack traces: both the original (minified) and resolved (source-mapped) versions
  • Context: browser, OS, device type, page URL for each occurrence

Alerts ​

The alerts page shows error spike events. Vantmetry monitors the error rate across all incoming events and triggers a spike when the rate exceeds a configurable threshold.

Each spike record shows:

  • When it was triggered
  • Duration (until resolved or "Ongoing")
  • Peak error rate (errors per minute)
  • Status (Active or Resolved)

Click a spike to jump to the Issues view filtered to that time range, so you can see which errors caused the spike.

Spike notifications are sent via your configured webhook (Discord, Slack, or ntfy) when they start and when they resolve.

Uptime monitoring ​

The uptime page performs periodic HTTP health checks against a URL you configure per project. Each check records:

  • DNS resolution status
  • TLS handshake status
  • HTTP status code
  • Response time in milliseconds
  • Error details if the check failed (timeout, connection refused, certificate error, etc.)

Status transitions (UP to DOWN or DOWN to UP) trigger a notification via your configured webhook. The first check that comes back DOWN also triggers an alert.

Check history is paginated at 50 records per page.

Multi-project support ​

The sidebar project dropdown lets you switch between projects. All views (issues, alerts, uptime, settings) are scoped to the selected project.
