Connectionless services deserve attention too
UDP doesn't confirm delivery, which makes it hard to monitor. UptimeAnchor sends a payload of your choice and checks that the service replies as expected.
Included in every plan: 5 free monitors checked every 5 min, down to every 1 min on paid plans.
- Host
- sip.example.net

How it works
Setting up a UDP monitor takes less than a minute.
- 1
Set host, port and payload
Define what to send to the service, as text or hex.
- 2
Send and wait for a reply
The probe sends the packet and waits for a reply within the timeout.
- 3
Content verification
If you set an expected reply, we check that it matches before marking the service as UP.
