From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What do you use to analyze journalctl? (lemm.ee)

Or any other log files/output? I'm open to any solution, but what I would like...

...is something where I can just click on a word or select some text and say "filter that out"

Something that colors different log levels differently, preferably automatically.

Something that can parse the "columns" and give me a nice quick list of values, like different unit names to filter out/solely include.

Something that lets me choose a time and go there. Something that lets me select only a specific timeframe of logs.

I know this can probably be done by going in/out of journalctl, recalling the last command and adding specific filter options... but it just feels slow. It's so many keypresses when I could just right click on the word and -> "Filter out/Search for" or something.

Sounds like you want a siem like Wazuh. Its agent can collect journald logs from any number of systems. It also has a gui you can interact with to parse logs.

Well, just a monitoring stack, like for example Grafana, would probably be more suitable for this specific task (if we're doing central hosting/collection).

Kind of my main recommendation is to use something with OpenTelemetry. It's pretty much the standard protocol for transferring logs, traces and metrics, so if you set everything up with that, then you can swap out the visualization software with less pain.
Here's a guide for Grafana + OpenTelemetry Collector: https://grafana.com/docs/loki/latest/send-data/otel/

I'm seconding this recommendation
