[Artemis] Detecting failure in AMQP

["Fuhrmann, Hauke" <Fu...@scheidt-bachmann-st.de>]

Hi there,

from this documentation [1]  I understand that Artemis has smart watchdog-ping mechanisms to detect failure either on server side or client side.
Whenever some ping is not received in some configurable interval, the connection is considered lost and action can be taken.

The question is whether this is a dedicated Artemis feature that only works with an Artemis Broker together with an Artemis Client? If the transport is AMQP and clients might use a different client library (maybe even a custom implementation close to the AMQP-Standard), is there a way to still use this feature with an Artemis Broker? So is there some more detailed information how the pings are actually sent? Is it a special queue? Special frame? Something AMQP inherent or something custom? Or not available with AMQP at all?

Cheers,
Hauke

As far as I remember the ping is part of the AMQP spec. (It follows a
different name I don’t remember now) So it shouldn’t matter what library
you used unless there is a bug with your client.
