Dietpi view installed services and status

General Discussion
1

Hi guys,
I like to have Node-Red Dashboard which shows me the status of running services from all my PI’s I do have in my LAN. At the moment I run the comman “sudo systemctl list-units --type=service --state=running -o json-pretty” as a cron job and afterwards I do send it to the dashboard via mqtt.
Problem:
On one of my PI’s the command (“sudo systemctl list-units --type=service --state=running -o json-pretty”) gives me the same result back as “sudo systemctl list-units --type=service --state=running” which is not in json and looks pretty bad and I can’t use it in node-red.
I have two options here but I only need on solution for this problem, hopefully some can help here.
My thoughts:

  1. Because I like the overview of services in dietpi, which shows me the services I have installed and the status (“sudo dietpi-services”). Does anyone know the command behind it?
  2. Alternative: Does somebody knows the issue, why my command is not giving me back the result as json?

Informations:

  • I tried both (-o json and -o json-pretty)
  • All PI’s are at the same dietpi version: DietPi v8.7.1

Best regards
Ben

dietpi-services is not a single command. It is a script containing a couple of functions to display the status.

3

The -o option only has an effect on systemctl status for the shown journal logs, not for systemctl list-units.

Hi Joulinar,
If one or more commands doesn’t matter even if it is a script, this is fine as long as it is not running longer than a second. Is it possible to provide thoses scripts for all?

I tried sudo systemctl list-units --type=service -o json-pretty and I get a pretty nice output, which looks different than without the -o json-pretty:

-o json-pretty formates it nicely (like in my example)
-o json removes just all spaces and empty lines (in comparison to json-pretty)
without the -o option it’s more like a table.

Yeah those are mine experience as well, but not on one PI which is strange. :slight_smile:
