UDP Monitoring for DNS, NTP, VoIP & Custom Services
Keep watch over the connectionless UDP services that power your stack — DNS, NTP, syslog, SNMP, SIP, and game servers. Send datagrams from locations around the world, confirm each service actually responds, and get alerted the moment one goes silent.
Comprehensive UDP Monitoring Features
Everything you need to keep your UDP services answering
Global UDP Checks
Send datagrams to your UDP services from multiple regions worldwide to measure real availability and response time from where your users and systems live.
Real Response Verification
Because UDP has no handshake, an open port tells you nothing. We verify the service actually replies, confirming it is alive and answering rather than silently dead.
Response Time Tracking
Measure how long each UDP service takes to answer on every check, so you can spot a degrading endpoint long before it stops responding entirely.
Smart Alerting
Get notified within seconds when a UDP service stops responding or response time crosses your threshold, via email, Slack, Discord, and webhooks.
Multi-Location Confirmation
Failures are confirmed from several regions before an incident opens, so a single dropped datagram or flaky path never pages you with a false alarm.
Any Host & Port
Point a check at any public host and UDP port, from standard services like DNS (53) and NTP (123) to your own custom application protocols.
Historical Trends
Review response time and availability over time with clear graphs and reports, ideal for spotting slow regressions and proving service reliability.
Flexible Scheduling
Set check intervals from 30 seconds to 24 hours and configure maintenance windows so planned work never triggers unwanted alerts.
Why Choose Our UDP Monitoring Solution?
Some of the most critical services in your infrastructure speak UDP, not TCP — and a simple port check can't tell whether they're actually working. Our UDP monitoring sends real datagrams and waits for a valid reply, so you know the service is genuinely answering. With global probe locations, multi-region confirmation, and response-time metrics, you get an early-warning system for DNS, NTP, SIP, and every custom UDP endpoint you depend on.
Monitor any public UDP service on any host and port
Verify real responses, not just an open port
Response-time and availability metrics on every check
Multi-location checks to rule out dropped datagrams
Confirmation from several regions before alerting
Built for DNS, NTP, syslog, SNMP, SIP, and game servers
Configurable thresholds and check intervals
Instant notifications via email, Slack, Discord, and more
How UDP Monitoring Works
Simple setup, real visibility into connectionless services
Add Your Service
Enter the host and UDP port you want to watch, and pick the regions you want to send datagrams from.
Set Thresholds
Define an acceptable response time and how many regions must agree before an incident is raised.
Monitor 24/7
Our global network sends datagrams to your service continuously, checking for a valid reply and timing each response.
Get Instant Alerts
When a service stops responding or slows past your limit, you get immediate notifications and a detailed incident timeline to act on.
UDP Monitoring Use Cases
Perfect for any connectionless service that must stay live
DNS & NTP Services
Keep your name servers and time servers answering reliably. A DNS or NTP outage cascades fast across an entire infrastructure, and UDP checks catch it before users do.
VoIP & SIP Endpoints
Confirm your voice and SIP signaling endpoints stay reachable and responsive. Silent UDP failures cause dropped calls and registration issues that TCP checks would never surface.
Game Servers
Most multiplayer game servers communicate over UDP for low-latency gameplay. Verify each server is genuinely answering and watch response time so players never hit a dead or laggy host.
SNMP, Syslog & Custom Protocols
Monitor SNMP agents, syslog collectors, and your own application protocols running on UDP. Make sure the services your tooling and apps rely on are actually responding around the clock.
