Question :
I’m trying to analyze some log files generated in Linux and I’ve noticed that it’s very annoying to understand where a line is starting / ending.
I would like to know if there is any kind of command or tools for better visualization of logs.
Example of a boring log generated by Mysql, seen from the command line:
Does anyone know how to report some tool for better visualization / monitoring of logs?
Answer :
Actually analyzing logs is a very boring task, but depending on the context you can use some tools such as pipe ( | ) followed by grep , for example, let’s say you want to “inspect” syslog for events generated by the kdeconnect application, then it would go into the logs directory and:
$ tail -n 30 syslog | grep kdeconnect

Multitail:
If you like something more oriented towards GUI, you can use multital. See screenshots .
Glogg:
Another good option (for ubuntu users, already in the repositories), is glogg, see the screens.
