Disconnection metrics

[HernanGastaud]

Hi,

I have a Pushpin stateful set deployed to manage our SSE connections, and I'm looking for a way to track client disconnections. From the exposed metrics, I couldn't find any related to disconnections.

Is there a webhook or any other mechanism available to listen for SSE client disconnections? For WebSocket connections, the backend receives a Disconnect event, but I haven't found an equivalent for SSE.

Looking forward to your guidance.

Best regards,
Hernan

Hi Hernan,

There is an upcoming feature called "gone" links, where you'll be able to get a callback by setting a response header like such:

Grip-Link: </disconnected/1234>; rel=gone

We will hopefully cut a new release within a few weeks.
