The new [Logging utility](https://docs.julialang.org/en/v1/stdlib/Logging/#Log-event-structure-1) is very nice. However, for debug logging, I often want to have several levels of verbosity e.g.

Level 1 - function entry point  
Level 2 - debug within function body  
Level 3 - debug within some kind of loop

What would be the best way to achieve that?

You can create your own LogLevel.

For reference, the `Debug` level is defined as `const Debug = LogLevel(-1000)`. Your custom level can then be defined as for example `LogLevel(-999)` for a higher importance (closer to `Info`) or e.g. `LogLevel(-1001)`, which is closer to `BelowMinLevel`. You can then log with that level using [`@logmsg`](https://docs.julialang.org/en/v1/stdlib/Logging/#Base.CoreLogging.@logmsg).
