How to set defaultMqttSessionExpiryInterval on MQTT acceptors

[eanbiso]

Hi support,
I would need to understand how I can configure the property 'defaultMqttSessionExpiryInterval' on an MQTT acceptor using Artemis in the k8s context.
Is this possible using the broker property "acceptorConfigurations.<ACCEPTOR_NAME>.extraParams.defaultMqttSessionExpiryInterval" in a way like this

apiVersion: broker.amq.io/v1beta1
kind: ActiveMQArtemis
metadata:
  name: artemis-mqtt
spec:
  acceptors:
    - name: mqtt-plain
      protocols: MQTT
      port: 1884
  brokerProperties:
    - "acceptorConfigurations.mqtt-plain.extraParams.allowLinkStealing=false"
    - "acceptorConfigurations.mqtt-plain.extraParams.defaultMqttSessionExpiryInterval=300"

?

Many thanks

Hi @eanbiso, your example is correct and it is the only way to set the property defaultMqttSessionExpiryInterval on an MQTT acceptor. You can double-check the extra parameters of an acceptor querying the jolokia api, i.e.

curl -u admin:admin http://artemis-mqtt-ss-0:8161/console/jolokia/read/org.apache.activemq.artemis:broker=\"amq-broker\"/AcceptorsAsJSON
