Is there a log viewer

Preferably in the Ubuntu repositories or available via PyPI/pip, but if the quality is really high having it only on Github should be ok as well.

At a minimum, the log viewer should have the following properties / features:

  • Remove the JSON syntax and display the logs in a nice way
  • Automatically update when the file is updated
  • Be able to handle big log files (10 MB should not be a problem, it would be nice if it could deal with 100 MB easily as well)
  • tail -f /var/log/logfile works good for me, sometimes I add a |grep servicename - ie, tail -f /var/log/syslog | grep named

  • @ivanivan Well... if you use this, you don't benefit from structured logs, do you? Jan 11, 2018 at 7:25
  • If you "remove" JSON (what logs have JSON inside, by the way?) you don't benefit from their structure either, do you? :) But yes, concerning tail I'm with you in this context. I sometimes use the "System Logs" tool that ships with the desktop (I'm using Mint Cinnamon) for structured view – and tail/less as well, depending on what I'm doing. System Logs should almost meet your requirements (not sure about the JSON part, though).

  • @Izzy I wrote "remove JSON syntax", meaning that it should not simply display it. I am new to structured logging and currently I don't know how it is better than usual logging, so I can't really tell which features a log viewer should have. Jan 11, 2018 at 7:58
