Re: [mosquitto-dev] Mosquitto connection disconnection message time

Thanks Carl/Roger.


Let me brief about my case.


Used apps :

Mosquitto 1.4.8 (broker)

Python 2.7.11 with paho.mqtt client module.

MQTT 3.1

Mqttwarn 0.6 (listener)


I have remote devices wanted to monitor their availability by using mosquitto/MQTT protocol.

We have prepared a python code (shared in previous email) to initiate connection from remote device to connect e device with management server.

And wanted to append record connect time at every connection initiated by remote devices.

and record disconnect time, IP, hostname (of remote device) with LWT messages after any timeout or abrupt disconnection from the remote device.


We tried at our end but it’s appending disconnection time as older time (when it was last connection made with broker).

Is it possible to generate any message from the broker at every connect and disconnect with remote device?


Example –


Publish message at connect:–

“IT works !!! connection made with broker” from IP – 10.x.x.x at <<date and time>>.


LWT message at disconnect: -

“IT works !!! remote device disconnected from broker” whose IP – 10.x.x.x at <<date and time>>.
