Is there an out of the box solution for monitoring websockets (bandwidth, number of connected clients, debugging tools) similar to datadog? (compatible with Nodejs)
Any message broker that support a messaging protocol (like MQTT) over Websocket will have that. Check out the free SaaS message broker at https://console.solace.cloud/ if it fits your need.
Would like this as well. Charles Proxy does not work for websockets well.
