Know it's down
before your customers do.
HTTP, TCP, DNS, and ping checks from distributed regions. Results flow into components, Alerting Core, and the status page your customers already trust.
Check types
Monitor everything with a pulse
Cover the edge, the origin, and the jobs that only fail when nobody is watching.
HTTP / HTTPS
Status codes, latency, redirects, headers, and response assertions — not just “did it return 200?”
TCP & ping
Verify databases, queues, and internal services are reachable — not only your public edge.
DNS checks
Catch resolution failures and unexpected records before they look like an application outage.
Assertions
Typed check config with an assertions list — validate the response shape that actually matters.
Performance budgets
Alert when latency degrades past your threshold — before slow becomes down.
Plan-aware intervals
Check as often as your plan allows. Entitlements enforce fair limits without surprise overages.
No false alarms
Confirmed failures,
not flaky networks.
Regional probes and Alerting Core work together so you get paged for real outages — not a single probe’s bad day.
- Multi-region probe execution
- Structured history for every check outcome
- Feeds components, incidents, and status pages
Check fails in a region
A probe records a timeout or assertion failure against your target.
Signal enters Alerting Core
Rules evaluate, dedupe, and decide who should hear about it.
Incident & status update
Open an incident, notify on-call, and reflect impact on components.
Core check types for edges and origins
HTTP & TCP
Catch network failures before apps look down
DNS & ping
Distributed probes, not a single vantage point
Multi-region
Structured outcomes you can trust and review
