I don’t believe uptime robot supports websocket connections (you can ping a port, but not upgraded connections - happy to wrong here though), but this is targeting wss:// and nostr relays specifically. So it can provide connection latency and read/write latency using nostr protocol (so you can know if there’s an issue returning data even if the connection is able to be made). Plus it will DM you on nostr if the status changes (and optionally you can provide an email).

We’ll likely extend it to support websocket monitoring more generically, but it sends REQS and Events as part of the latency checks today and is pretty coupled to relays.
