Datagram probe — UDP has no handshake, so send a message and match the reply.
Every UDP monitor runs on the same spine as the rest of PulseTrace — probed from each region you pick, scored on every check, and streamed into one timeline where incidents open on their own, anomalies surface without a threshold to guess, and reports are generated for you. Point it at a target, choose an interval, and it's watched.
What each check verifies

For UDP services where a request/response pair proves liveness — DNS servers on 53, NTP, syslog receivers, game servers, custom telemetry. You provide the payload to send and the response to expect.
ntp.internal:123 is DOWN — no response within 2 s from eu, asia.
