Question regarding verbose logs upon CT fetcher startup #1030
Description
Hi there,
this is more of a question than an actual issue. When starting my application and all the workers for the individual CT logs, I get a lot of log spam:

...
This is due to these lines of code:
certificate-transparency-go/scanner/fetcher.go
Lines 120 to 123 in 3f5a6e9
Now my questions are:
- Do you know of a way how to configure the klog library to only log specific log levels? I read about
-v, but i have no such flag specified for my CLI - Do you think the lib needs to be that verbose by default when starting up the log workers?
Cheers,
