howdy y'all. I'm hosting a go app on railway and it's been great but whenever I use go's default logger or charm log, all of my logs show up as errors instead of info. I have tried modifying the default logger's output to ensure it's not printing to standard err but it's still categorizing all of my logging as errors. Just wondering if anyone has any insight as to why this is happening.

you are on the right track, sending logs to stdout instead of stderr would print them as info, can you please provide a minimal reproducible example for me to test

i tried both log.Default().setOutput() and log.setOutput() and both seem to send to stderr anyways

little tip but it has nothing to do with logs - port := cmp.Or(os.Getenv("PORT"), "8080")
saves 3 lines haha

capitals for public methods is right. I've been writing too much rust

okay so it looks like you just can't set the default logger's output to stdout

but making a new logger with stdout as its output seems to fix the problem

if i'm being serious it's mostly that i appreciate them having a lot of different log levels that are visually differentiated instead of just either crashing the program or not

interesting postscript to this: it looks like my original fix actually was working for some logs but not others. I'll have to do some digging to see what's different between them

and this is incredibly silly

my original fix totally worked: it redirected all of the charm logs to stdout instead of stderr


jkellogg01

but my logging middleware was using stdlib log instead of charm log, so it didn't apply to those
