Thin edge tedge-mapper-c8y failed to start

HI,

I have thin edge 0.10 installed on a raspberry. It was working good, but now after a reboot the c8y mapper cannot start anymore generating permission denied error.

pi@raspberrypi:/var/log/tedge/agent $ sudo systemctl status tedge-mapper-c8y

Anyone can help here?

thanks

Please update to the latest version first (currently 0.13.1) using the instructions here: Install | Thin-edge

Hi

I don’t want to upgrade now as MQTT API changed in 0.13

Mauro

Which is the way to upgrade it to 0.12 ?
This should support the old MQTT topics /tedge/ ?

thanks

Mauro

Yes the tedge/ topics are still supported in the new MQTT API (except for the service status). So you shouldn’t notice the difference in most circumstances.

But we still strongly encourage users to start updating the topics, a guide on the old to new topic mappings is available from the official docs:

Hello Reuben

I did update thin edge to 0.13.1 and after some tricks it is now connecting and sending data to C8y.

O C8y Service management now I see services duplicated with wrong status information:

how can I clear that?

thanks

Mauro

We posted some instructions in the release notes.

Unfortunately there is no easily way to do this via the UI , however if you are familiar with go-c8y-cli then it is fairly trivial.

thanks Reuben! that’s clear!

Hi Reuben,

sorry if I reopen this discussion. Once I cleared out the duplicated services from c8y. Now I have a misalignment between running services on thin edge and info on c8y.

For example the c8y mapper it is running on edge:

pi@raspberrypi:/lib/systemd/system $ sudo systemctl status tedge-mapper-c8y.service
● tedge-mapper-c8y.service - tedge-mapper-c8y converts Thin Edge JSON measurements to Cumulocity JSON format.
   Loaded: loaded (/lib/systemd/system/tedge-mapper-c8y.service; enabled; vendor preset: enabled)

   CGroup: /system.slice/tedge-mapper-c8y.service
           └─572 /usr/bin/tedge-mapper c8y

but the status on c8y is down. Also from tedge watchdog logs I can see this:
