Ask HN: What do you use to view logs?

I guess many people use Graylog, Splunk or similar web-based systems (which can be self-hosted if you like) and are content with that. Not sure if there are any readymade applications for using locally on your Mac.

Maybe you can hack something together with jq + Bash + awk etc?

These tools might also be useful:

Best of luck!

The Logfile Navigator (https://lnav.org) is a TUI for viewing log files that can be configured to process structured JSON files. It has quite a few features, like filtering and color coding.

The documentation for writing a format file is here -- https://docs.lnav.org/en/latest/formats.html

The format file tells lnav what common fields are in the log messages and how to format them into plaintext for display. Here's an example configuration for JSON logs -- https://github.com/tstack/fullsail_lnav_config/blob/master/f...

Lame but powerful option: `tail -f /logfile.log | grep -A10 -B10 <interesting thing>`. (prints 10 lines before & after search lines). The most powerful feature I've had in log management is the ability to search for what was interesting, and no tool can provide you a "this is interesting" button. If you've got performance concerns ripgrep is a drop-in grep replacement that's very fast.

Graylog. It’s surprisingly quick and easy to get going. Here’s a good starter video.

Is http://www.logtailapp.com/ too simple or would it work?

Graylog for centralized logging, jless locally.
