First - Relayguardian is free!
What tools are you using to evaluate uptime/performance of your websocket?
We have lots of http monitoring for our websites and backends but I had trouble finding a good out of the box solution for nostr relays.
RelayGuardian connects, makes a nostr REQ and writes a nostr event to verify the relay is not only reachable but functioning. If there’s something out there that offers this please share it with me!
