Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna

LogSight v1.0.0

A desktop log file viewer.



Features:
• Multiple highlights.
• Multiple filters.
• Multiple log formats. A log format contains the parser definition to split the log file in columns as well as the various highlights and filters defined for it. LogSight remembers which log format was used for which file.
• Auto-scroll mode, similar to tail -f.
• Can work on local files and stdin.

Supported operating systems:
Windows 7 or later and Linux.

User Guide:

Defining the parser:
The parser definition is a regular expression with named groups.
For example, given the following log lines:
12:34:56 myapp:1234 debug Start app
15:16:54 myapp:1234 warning Something went wrong


To create a parser which splits this into time, app, pid, level and message columns, you could use the following definition:
(?<time>\d+:\d+:\d+) (?<app>\w+):(?<pid>\d+) (?<level>\w+) (?<message>.*)

The log file view updates in real time as you type.

Defining highlights & filters:
A highlight is made of two elements: the highlight condition and the highlight colors. A filter only contains conditions.
The highlight condition uses a simple DSL inspired from the Wireshark DSL. Its syntax is:
<column> <operator> <criteria>
• column is the name of a column defined in the log parser
• operator is one of:
= or ==: exact match
contains: the cell must contain the criteria string
~: the cell must match the criteria regular expression
• criteria is the string to match. If it contains spaces, you must surround it with ".
To use a literal ", escape it by prefixing it with another ".

LogSight does not use \ to escape strings, because it makes entering regular expressions painful.

Known limitations:
• LogSight currently loads all the log file in memory, so you should not try to use it on multiple gigabyte log files. That should be fixed in future updates.
• LogSight does not support compressed log files for now.
