Wizard that help to set the logformat for a logfile. Select the delimiter to use to separate subjects in the logmessage. The table at the bottom of the dialog will show the formatted logmessages as an example. Next to a number of preconfigured delimiters the wizard supports also supports regular expressions. Regula expressions can be used as a split expressions or as a match expression. In the figure below a sample is shown of a match expression to format the apache access_log format. When the first row of the logfile contains the columnnames activate the checkbox to collect the column names otherwise add the required columnnames in the box to the right. If your logs contain timestamp data you can decide to let TailExpert interpret the timestamps (this function has a speed penalty) which will enable TailExpert to automatically sync the timestamps of two logviews when messages arrive.
