Monitoring

Logs, metrics, alerting. What vly provides out of the box, plus integrations for deeper observability.

Every vly project includes basic monitoring out of the box. For production apps with significant traffic, add a dedicated observability platform.

Built-in

Deployment logs

Build output, type errors, deploy status. Live in the deploy dashboard.

Function logs

Console output from Convex functions. Filterable by function, environment, severity.

Error tracking

Uncaught errors in the frontend and Convex functions. Stack traces, breadcrumbs.

Basic metrics

Request count, latency p50/p95/p99, error rate. Per environment.

For production-grade observability

Add one (or more) of:

Sentry

Error tracking + performance monitoring with rich context.

PostHog

Product analytics + session replay. Tracks user behavior, not just errors.

Datadog

Enterprise-grade APM, logs, metrics, alerting in one place.

LogSnag

Lightweight event tracking and notifications.

Alerting

vly’s built-in alerts:

• Deploy failures (email to workspace owner)
• Build errors persisting for 1 hour
• Function error rate > 5% for 5 minutes
• Storage / credit usage thresholds

For richer alerting (PagerDuty, Slack, etc.), use Sentry / Datadog integrations.

What to monitor

Metric	Threshold	Why
Function error rate	> 1%	Bugs or downstream API issues
p99 latency	> 1s	Performance regression
Auth failure rate	> 5%	Possible brute-force attempt
Stripe webhook failures	> 0	Money flow at risk
Unique users / day	drop > 20%	Possible auth or onboarding break
