Lmst

So I'm googling+udm14 if someone has made an lnav format for minecraft (client + server) logs: "lnav minecraft log".

First link is the #lnav page, but without mentioning #minecraft.

Second link is from minecraft wiki:

"There are nine types of logs: oak, spruce, birch, jungle, acacia, dark oak, mangrove, cherry blossom, and pale oak; and two types of stems: crimson, and warped."

Right... I need to be more specific.

#unix

(Joke aside, it should be #log4j, but lnav doesn't recognize it.)

PS: I also discovered you can modify the `lnav` behaviour by only showing new logs at the time of using the SSH command above:

```
#!/usr/bin/env bash

export TZ='Europe/Berlin';
NOW="$(date -Iseconds | sed -e 's/+.*$//')"
LOG_FILE="$(ls -t ~/pgdata/data/logs/*.log | head -n 1)"

if [ "$1" = "now" ]; then
lnav "$LOG_FILE" -c ":hide-lines-before $NOW"
else
lnav "$LOG_FILE"
fi
```

#ssh #lnav #postgresql #postgres #trigger #debugging #troubelshooting #pg_net #supabase

I ended up adding an SSH user called `postgreslogs` which serves as a way to SSH directly into the logs using:
- A `ForceCommand` SSH daemon config for the user
- A `sudoer.d` config to allow postgreslogs to elevate (i.e. sudo) to postgres (the DB admin account) without a password

Works really nicely! All you need to do to see the logs is to `ssh postgrelogs@postgreshost.proxmox` or similar!

#ssh #lnav #postgresql #postgres #trigger #debugging #troubelshooting #pg_net #supabase

Today I discovered "lnav"or the Log Navigator cli utility. It is a truly awesome log follower and navigator for the terminal which works beautifully with PostgreSQL log files.

Cool, das kannte ich noch nicht: #lnav

#lnav, short for Log File Navigator is a command-line tool designed to make log analysis more intuitive and efficient.

I like the functionality to execute SQL queries directly on log files and today I discover that I can visualize data using #Gantt charts 😋

You can test lnav from your terminal `ssh playground@demo.lnav.org` and there is also a tutorial `ssh tutorial1@demo.lnav.org`

It’s an amazing #log viewer, and if you ever need to look at logs on #Linux (locally or remotely), do yourself a favour and check it out.

@C_Duv @usul Intéressant aussi #lnav, et c’est dans les paquets de ma distro. Merci !

Log View Viewer für macOS ???
Es ist keine wirkliche Freude auf einer Sophos Firewall die Logfiles durchzustöbern. Zum Glück gibt es dort aber die Möglichkeit, besagtes Logfile sich runterzuladen. Nun war ich auf der Suche nach einer App, mit der man größere Logfiles einigermassen angenehm durchsuchen und darstellen kann. Ich habe aus dem Mac AppStore die App "

@jschauma add a segment on #log parsing to your #systemadministration class (if you see fit). It's painful to learn from scratch with no guidance. The class is already wonderful, but I think that's something that I could have benefited from, given my current headache and work assignment.

My current solution is a combination of #ripgrep, #lnav, and profuse swearing and sweating! If that's the best anyone has figured out though, so be it!

Just a quick shoutout to the #lnav log analyzer. It makes my life so much better. It’s #FOSS for small #server setups and works on pretty much any #Unix system. If you’ve ever used #multitail, this is for you.

“Many logging tools, like Splunk, provide great features but are optimized for large-scale deployments. They require installing and configuring servers before they can be effectively used. There is still a need for a robust log file analyzer for the terminal.”

#lnav is a log file navigator.

lnav is a program which reads log files and displays their combined contents in chronological order. lnav highlights and colorizes relevant or important information, including actions and errors. lnav understands several log formats, can create timestamped logs from any program output, and can filter by regex or SQL.
