Since viewing log files can be some kind of annoying when you are only interested in a special problem I wrote a patch to filter/highlight specific sections of a logfile with gnome-system-log. A screenshot says more than thousand words:

The filters are based on regular expressions and should thus be quite flexible. The work was done (and paid) by Openismus Gmbh!

    That’s OK in this case, but if the messages you want are few and far between, it seems you want to make the irrelevant messages disappear. That is, make it look like what Evolution or Thunderbird does when you search for a pattern (show only the matching messages).

      Well, there is a checkbox to hide all messages that do not match any filter. I think this is what you want. It’s not that great yet as it doesn’t hide the empty lines but I trying to get this working, too.

    Good work mate, just wondering if the patch works for the new rewritten gnome-system-log (2.26)?

    This looks good, the red makes it a little hard to read, making it a lot lighter will help.

    • jhs Says:

      The red is just an example. You can configure background and foreground color for each filter.
