Hi, as this is an application specific issue you might find more relevant help on the Prometheus support forums.

https://discuss.prometheus.io/

Generally, it looks like your installation of Prometheus hasn’t worked, the system service is trying to start “/usr/local/bin/prometheus” and getting a “permission denied” error. This would indicate that the file you are trying to execute (/usr/local/bin/prometheus) isn’t marked as an executable file. If the issue is as simple as the installer not setting the correct permissions, you could rectify this specific issue with;

sudo chmod +x /usr/local/bin/prometheus

However I would recommend you investigate “why” the file has apparently been set with the wrong permissions in the first place.
Sometimes directly fixing an apparent error doesn’t always solve the “problem”.
