Keep your UDP-based services running smoothly. Monitor DNS resolvers, VoIP servers, game servers, and streaming endpoints with purpose-built datagram health checks.
UDP (User Datagram Protocol) monitoring is the practice of verifying the availability and responsiveness of services that operate over UDP rather than TCP. Unlike TCP connections, UDP is connectionless - there is no handshake, making monitoring more nuanced and requiring specialized probe techniques.
Many critical services rely on UDP: DNS resolvers (port 53), VoIP and video conferencing (SIP, RTP), online gaming servers, streaming media, and IoT telemetry endpoints. If these services go down, your users experience failed lookups, dropped calls, laggy games, and interrupted streams.
UptimeMonitorX provides enterprise-grade UDP monitoring that sends properly formatted datagram probes to your UDP endpoints at configurable intervals. Each check validates that the service responds within your defined timeout threshold, and alerts you instantly if it becomes unresponsive.
Send custom datagram payloads tailored to your specific UDP service protocol. Verify that the service not only accepts connections but returns expected responses.
Built-in support for common UDP protocols including DNS, NTP, SNMP, SIP, and custom game server query protocols. No manual packet crafting required.
Validate response payloads against expected patterns. Detect silent failures where a port is open but the service is not functioning correctly.
Measure round-trip time for UDP request-response cycles with sub-millisecond precision. Track latency trends to spot degradation early.
Monitor multiple UDP ports on the same host simultaneously. Cover DNS, VoIP, and game services from a single monitor configuration.
Receive alerts via Email, Slack, Telegram, Discord, or WhatsApp the moment a UDP service becomes unresponsive or exceeds latency thresholds.
Configure your UDP endpoint - Enter the host address, UDP port, and select the protocol type. Optionally define a custom probe payload and expected response pattern.
Continuous datagram probing - Our monitoring infrastructure sends UDP probes at your configured interval. Each probe is crafted according to the target protocol specification.
Response validation & timing - We validate the response against your expected pattern and measure round-trip latency. Failed or timed-out probes trigger the alert pipeline.
Alerting and analytics - View latency trends, availability charts, and response time distributions on your dashboard. Receive instant alerts through your preferred channels.
TCP monitoring establishes a full connection handshake, while UDP monitoring sends stateless datagram probes. UDP checks require protocol-specific payloads to verify the service is actually responding.
Yes. UptimeMonitorX supports common game server query protocols. Configure the appropriate probe payload for your game server engine and monitor availability and latency.
UDP is connectionless, so the absence of a response within the timeout window is treated as a failure. You are alerted immediately when configured thresholds are breached.
UDP monitoring is available on all plans. Free plans include basic UDP checks, while Pro plans unlock custom payloads, shorter intervals, and advanced analytics.
