logstation

Tails a set of log files and serves them up on a web server with syntax colors via regex.

Binaries available in releases. See usage below.

Focus on:

• Support for both Windows and Linux
• Support as many browsers as possible
• Support for Java 1.6+
• Ease deployment and usage by generating fat jars with minimal configuration required

Developed with Scala, Akka, Lift, Comet (Ajax Push), and JavaScript.

Usage

• Call java -jar logstation.jar
• It will create an logstation.conf in your current directory and exit
• Update logstation.conf
• Call java -jar logstation.jar again to start it
• Navigate to http://127.0.0.1:8884 to start tailing

Can also use -c your-logstation.conf argument

logstation.conf example

logstation {
    # Windows example of setting up logs
    logs=["C:\\git\\logstation\\test\\logfile.log","C:\\git\\logstation\\test\\logfile2.log"]
    # Unix example of setting up logs
    # logs=["/home/jdrews/git/logstation/logfile.log","/home/jdrews/git/logstation/logfile2.log"]

    # Setup your syntax below
    # <some-name>=[<RGB_HEX>,<regex-for-line-matching>]
    # matching gives priority to the top most
    syntax {
        # red
        error=["#FF1F1F",".*ERROR.*"]
        # yellow
        warn=["#F2FF00",".*WARN.*"]
        # green
        info=["#00FF2F",".*INFO.*"]
        # blue
        debug=["#4F9BFF",".*DEBUG.*"]
        # cyan
        trace=["#4FFFF6",".*TRACE.*"]
    }

    # Web Server Port
    #    The port used to connect to the LogStation
    webServerPort=8884

    # Number of lines to display per log file
    #    any logs over this will truncate the oldest lines from the page
    maxLogLinesPerLog=500

    # Number of messages to buffer on server
    #    These will be sent to any new connections so they have some history of logs
    #    bufferLength is multiplied by number of logs, and buffered on best effort for each log
    bufferLength=10
    
    # Unique name for logstation instance
    #    This name will be prepended to the browser tab
    #    Can be useful when connecting to multiple logstations
    logStationName="dc10srv42"
