MacOS – How to send logs to the main screen of OSX Console

consolelogsmacos

As an application developer, how can I send logs so that they appear on the main screen of Console, i.e. when I select the name of my computer under "Devices?"

So far, I have successfully sent logs to:

"Log Reports" under "Reports" by writing a log file within ~/Library/Logs/
"system.log" under "Reports" by sending logs with syslog using RFC 3164

I'm currently on MacOS Catalina 10.15.1 with Console 1.1 (4.0.15).

As I'm not actively coding under macOS, I would say with some reservation: This might be worth reading: https://developer.apple.com/documentation/os/logging

Console.app's logs are stored in the following locations:

/var/log
/Library/Logs
~/Library/Logs

To back up all the logs, simply copy the contents of these three folders to another location.

To back up a single log, look in Console.app for the log that you want to back up, select it in the sidebar, then press ⌘R (or right-click and select Reveal in Finder). This file can then be copied to another location.

It looks like there isn't any way to nicely format JSON for the console app, but you might be able to use the tagging system for some increased clarity.

Probably a better idea to include instructions on how to open the log in a more capable program.
