Is it possible to configure log levels for specific loggers before launching an application in the Vision client? I know they can be adjusted from the diagnostics popup after launch, but I’m wondering if there’s a way to set them in advance.

Do you need it to happen before anything else has happened, or does "before other scripts have run" suffice?

You could drop calls to `system.util.setLoggingLevel` in a client startup script if the latter is sufficient:

> **[system.util.setLoggingLevel | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-util/system-util-setLoggingLevel)**
>
> Sets the logging level on the given logger.

I would prefer the former if possible.

I tried putting a `system.util.setLoggingLevel` script in a client startup script but it seems like it cannot find the logger.

This is my script. The logger name I’m using is the same I see in the vision client diagnostic popup  
`system.util.setLoggingLevel("vision.binding.indirect-tag-binding", "debug")`

However I get this error when starting the vision client project:

`ValueError: Unable to change logger level: NameError: The Logger vision.binding.indirect-tag-binding could not be found.`

Try preceding that line with `system.util.getLogger(...)` to force creation of that logger.

Oh I see. Adding the `getLogger()` before setting it made it work!
