Monitoring - MQTT Client by TELEGRAM

wseixas

I would like to monitoring a client mqtt sending messages to telegram.
For example:
When this client disconect I would like to send telegram msg

wseixas You question about how to design this or you want some code pieces?

There are two distinct approaches in implementation of this:

Handle disconnects or wrong situations in your mqtt client.
Use another application subscribing to logs from MQTT Broker and resending appropriate logs to Telegram via bot API.

Which one you prefer?

I have a pipeline in python receiving messages from device and posting it in other platform.
Some time this pipeline is down ...
I really don't know why ... then I restart this pipeline and it work again some days and donw again ...
I decided to create a alert to monitoring this pipeline

wseixas In that case I recommend to use external monitoring - e.g. approach #2.

Create another python script, use master token to connect to flespi and subscribe it to the topic flespi/log/mqtt/sessions/+/+.

It will receive flespi/log/mqtt/sessions/XXXX/accepted and flespi/log/mqtt/sessions/XXXX/closed messages with informational payload where XXXX is client-id. You may even subscribe to exact client-id.

Try it from MQTT Board (external or embedded into flespi.io) and login/logout to flespi.io.

Do you need to help with how to send messages to Telegram?

Maybe option 2 is better. I need to give my customer information

Here is how messages to flespi/log/mqtt/sessions/# looks like, should be enough information to control and notify about the changes:
