Possible disadvantages of LNAV

  • Learning Curve
    Although LNAV is powerful, it has a steep learning curve for new users unfamiliar with its functionalities and command structure.
  • Limited GUI
    LNAV's interface is entirely text-based and runs in the terminal, which might be less appealing to users who prefer graphical user interfaces.
  • Performance Issues with Very Large Logs
    While LNAV performs well with moderately large logs, it may struggle with very large log files or require significant system resources to process them.
  • No Built-in Alerting
    LNAV does not have built-in mechanisms for alerting on specific log events, which means additional tools or scripts are required for comprehensive monitoring solutions.
  • Dependency on Terminal Features
    LNAV relies on specific terminal features and capabilities, which might not work consistently across all terminal emulators or remote environments.
  • Lack of Advanced Visualization
    Compared to some other log management tools, LNAV lacks advanced visualization options such as charts and graphs, which can make data interpretation harder for some users.

Possible disadvantages of glogg

  • Learning curve
    While Glogg provides many features, new users might find it difficult to learn how to use the tool effectively without proper documentation or tutorials.
  • No built-in analytics

  • UI limitations

  • Scalability concerns
    Handling extremely large log files can sometimes be an issue, although Glogg is generally very efficient, performance might degrade with very large data sets.

  • SQLite: 35% Faster Than the Filesystem
    There’s a tool called lnav that will parse logfiles into a temporary SQLite database and allows to analyse them using SQL features: https://lnav.org/. - Source: Hacker News / 10 months ago
  • ht: Headless Terminal
    As others have kinda alluded to, it could be useful for testing TUI applications. I develop a logfile viewer for the terminal (https://lnav.org) and have a similar application[1] for testing, but it's a bit flaky. It produces/checks snapshots like [2]. I think the problems I run into are more around different versions of ncurses producing slightly different outputs. [1] - - Source: Hacker News / 11 months ago
  • Ask HN: Interesting TUIs (text user interfaces), maybe forgotten ones?
    The Logfile Navigator (https://lnav.org) is a log file viewer/merger/tailer for the terminal. It has some advanced UX features, like showing previews of operations and displaying context sensitive help. For example, the preview for filtering out logs by regex is to highlight the lines that will be hidden in red. This can make crafting the right regex a bit easier since the preview updates as you type. lnav... - Source: Hacker News / about 1 year ago
  • Angle-grinder: Slice and dice logs on the command line
    See https://lnav.org for a powerful mini-ETL CLI power tool; it embeds SQLite, supports ~every format, has great UX and easily handles a few million rows at a time. - Source: Hacker News / about 1 year ago
  • Toolong: Terminal application to view, tail, merge, and search log files
    The code base seems like a good reference as a small Python project. My fav option in this class of apps: https://lnav.org/ It lets you use journalctl with pipes as requested here: https://github.com/Textualize/toolong/issues/4. - Source: Hacker News / about 1 year ago

  • Separate dump files for the top 20k subreddits

    I've been using https://glogg.bonnefon.org/. The mark / matches feature is really handy. However there are a few bugs with highlighting and it hasn't been updated in a while. Will have to check this out! - Source: Hacker News / over 2 years ago
  • Searching inside large single-line text files?
    There's a multi-platform GUI tool glogg that 's very good for browsing and searching files that break normal editors (long lines in particular tend to kill editors even with word wrap enabled). Source: almost 4 years ago
  • Use the 'Tail' Command to Monitor Everything
    For a nice GUI log file viewer, I really like glogg ( https://glogg.bonnefon.org/ ) which is avaialble windows/mac/linux. - Source: Hacker News / almost 4 years ago
