LogoRRR Help

Getting started with LogoRRR

Install LogoRRR, open your first local log file, and complete a useful visual investigation.

LogoRRR is a desktop application for macOS, Windows, and Linux. It reads local text logs, keeps normal analysis on your computer, and presents the same source through a heatmap, text rows, a minimap, and an optional timeline.

Install LogoRRR

Open the download page and choose the package for your platform. The platform store or installer handles installation; LogoRRR does not require you to install a separate runtime.

When LogoRRR starts without a restored session, the empty workspace says Drop any text file here.

Open a log file

Use whichever route fits your source:

  1. Choose File → Open… and select a readable text file.
  2. Drag one or more files onto the LogoRRR window.
  3. Drop a directory to open its regular files.
  4. Open or drop a supported archive to unpack a support bundle.

Files open progressively in tabs. Dropping the same file again selects its existing view instead of creating a duplicate. LogoRRR supports up to 30 open files across the main window and detached windows; if a directory contains more files than fit, you can open only the newest files or cancel.

Start with one representative file.

Learn the heatmap and search workflow on a familiar log before opening a large support bundle.

Complete a first investigation

1 Scan the visual shape

Look for dense regions, repeated colors, long quiet stretches, and sudden bursts.

2 Add a signal

Press Shortcut+F and search for a literal such as ERROR, WARN, or a request identifier.

3 Narrow the view

Turn off Unclassified to keep only rows matching an active search term.

4 Carry the evidence

Select the relevant rows and copy the visible context to a ticket, message, or notes.

Search terms have their own colors. Those colors stay coordinated across the heatmap, text view, minimap, timeline, and rich clipboard output, so a signal keeps the same visual identity as you move through the file.

Add time when the log supports it

If each line starts with a timestamp in fixed columns, open Timestamp settings. Select the exact timestamp characters and enter the matching pattern, or explicitly ask the timestamp assistant to propose both values. Valid settings enable time labels, timeline navigation, and time-range filtering.

See Time patterns and timeline for formats and examples.

Resume later

LogoRRR remembers relevant workspace state, including open files, scroll positions, view visibility, search state, timestamp settings, main-window geometry, and detached windows. If a previously opened file is missing or unreadable, LogoRRR reports the problem without leaving a broken partial tab.
