LogFusion: Real-Time Log Monitoring Made Easy

Row Highlighting

Use LogFusion's powerful custom highlighting to match text strings or regex patterns and format the matched log lines to suit your needs.

Advanced Text Filtering

Use LogFusion's Advanced Text Filtering to filter and hide lines that don't match your search text, all in realtime as new lines are being added. Complex queries allow you to easily narrow down your results.

Watched Folders

LogFusion can automatically add new logs from Watched Folders. Just specify the folders to monitor, and LogFusion will automatically open any new log files created in those folders.

Log Categories

Create Log Categories to set up default settings for logs, such as highlighting and custom columns. Log Categories save you time, and make setting up newly loaded logs a breeze.

Custom Columns

Create custom column definitions and let LogFusion parse and split the log lines into your custom columns for easier reading.

Sync Highlight Rules

LogFusion Pro can sync your highlighting rules online, allowing them to be easily loaded and updated from any computer where you are logged in.

Auto-Scroll (like 'tail')

Just like the 'tail' program on Linux/Unix, you can use LogFusion to show the newest lines in a log in realtime.

Supports Many Log Types

LogFusion can read any text log files, like server logs or application debug logs. You can also view local and remote Windows Event Logs and Event Channels, and even capture text from OutputDebugString function calls for easy application debugging.

Scrollbar Highlight Markings

LogFusion's scrollbar shows indicators for highlighted lines in the log file, making it easier to locate lines that match your highlight rules, especially in large log files.

@SwiftOnSecurity

Honestly the ability to live-filter events in a GUI with a syntax like
username7 -warning -code589 -debug
is so awesome and helps me fix problems really fast.
Yes there's other ways to do it I just like this one a lot.

Love the product, bought it on a whim with DisplayFusion and have been pleasantly surprised. I've used a lot of log tools over years.
