[HELP] thingsboard gateway modbus-rtu

[KarimSayedAmir]

Hello together,

I updated the Gateway to 3.4.3

I tried my best to solve the issue but i am stuck.

I gett the following console ourput: owipex_adm@owipexTest://var/log/thingsboard-gateway$ systemctl status thingsboard-gateway ● thingsboard-gateway.service - ThingsBoard Gateway Loaded: loaded (/etc/systemd/system/thingsboard-gateway.service; enabled; vendor preset: enabled) Active: active (running) since Sun 2023-11-26 01:47:59 CET; 12s ago Main PID: 1452 (python3) Tasks: 34 (limit: 4416) Memory: 44.0M CPU: 6.366s CGroup: /system.slice/thingsboard-gateway.service └─1452 /usr/bin/python3 -c "from thingsboard_gateway.tb_gateway import daemon; daemon()"

After I switch manually on the Dashboard the Logging Lever to a new state for example from "DEBUG -->INFO" it changes to this:

owipex_adm@owipexTest://var/log/thingsboard-gateway$ systemctl status thingsboard-gateway ● thingsboard-gateway.service - ThingsBoard Gateway Loaded: loaded (/etc/systemd/system/thingsboard-gateway.service; enabled; vendor preset: enabled) Active: active (running) since Sun 2023-11-26 01:47:59 CET; 5min ago Main PID: 1452 (python3) Tasks: 43 (limit: 4416) Memory: 44.5M CPU: 1min 20.710s CGroup: /system.slice/thingsboard-gateway.service └─1452 /usr/bin/python3 -c "from thingsboard_gateway.tb_gateway import daemon; daemon()"

Any ideas? Thanks for the effort.

Hi @KarimSayedAmir,

Thank you for your interest in ThingsBoard IoT gateway. Please try to make a backup of your configuration, remove the old gateway and install a version 3.4.3.1 it contains minor fixes for logging system and may help with this issue. Let us know about results.

[KarimSayedAmir]

Hi @imbeacon,

thanks a lot for the quick reply. I will check this today and give you feedback. Have a nice day.

Hi @imbeacon,

actually I am getting this now: owipex_adm@owipex:/boot/firmware$ systemctl status thingsboard-gateway ● thingsboard-gateway.service - ThingsBoard Gateway Loaded: loaded (/etc/systemd/system/thingsboard-gateway.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2023-11-27 21:54:54 CET; 2min 1s ago Main PID: 1764 (python3) Tasks: 29 (limit: 4416) Memory: 43.5M CPU: 45.666s CGroup: /system.slice/thingsboard-gateway.service └─1764 /usr/bin/python3 -c "from thingsboard_gateway.tb_gateway import daemon; daemon()"

1.)Can this be connected to the Ubuntu 22.04 right management?

2.)Strange thing is that if I am using my own Modbus Lib, i can read the sensor easily.

Have great evening BR Sayed

Hi could solve the first issue:

The installation was done over the deb package. I created the missing folder: sudo mkdir -p /var/lib/thingsboard_gateway/logs`

Then i had to add permissions:

sudo chown -R thingsboard_gateway:thingsboard_gateway /var/lib/thingsboard_gateway/logs sudo chmod -R 755 /var/lib/thingsboard_gateway/logs

Now the log looks like this: owipex_adm@owipex:/boot/firmware$ systemctl status thingsboard-gateway ● thingsboard-gateway.service - ThingsBoard Gateway Loaded: loaded (/etc/systemd/system/thingsboard-gateway.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2023-11-27 22:16:29 CET; 4min 37s ago Main PID: 1906 (python3) Tasks: 17 (limit: 4416) Memory: 42.8M CPU: 57.537s CGroup: /system.slice/thingsboard-gateway.service └─1906 /usr/bin/python3 -c "from thingsboard_gateway.tb_gateway import daemon; daemon()"

But the sensor is still not reading. BR Sayed
