Adding remote targets in prometheus.yml

[feloxxx]

hello everyone, I have installed Prometheus and now I want to add more targets to the prometheus.yml.
To do this, I open the file prometheus.yml in this path:
/home/yellowtent/appsdata/97a95880-aba9-44ad-bcda-237c3c433880/data/config

i add this

• job_name: <SYSTEM-NAMEN>
  scrape_interval: 5s
  static_configs:
  - targets: ['<MY-IP:9100']

after restart the Prometheus didn't start again. i see the changes in the file manager.

when I remove the lines again, everything works fine again. What am I doing wrong? Can you please help me?

Thank you in advance, Felix

Firstly I would advice to edit the file with the Cloudron Filemanager not directly in the root / as root from the system level.

The Log viewer will tell you why the app is not starting. Probably some yaml error?

Hello and thank you very much for the quick response from you. Editing the file in the ROOT system as well as with the File Manager has the same effects. Here is the log file: thank you very much felix

please post your yaml with removed / redacted sensitive information in a code block and not plain.
You can also always use

e.g. :

job_name: <SYSTEM-NAMEN>
scrape_interval: 5s
static_configs:
  - targets: ['<MY-IP:9100']

yamllint is also a great to to check if you yaml file is valid.
