glogg | Refresh not working

[Gerald Sagmeister]

Hi there,

First of all great log editor, could become my favourite, but there is one thing that is not working in my environment.

It doesn’t really follow the file, if i click „Follow File“ it jumps to the end but doesnt display the new lines.

If I press „Refresh“ new lines are there.

I also played around with Advanced -> Enable polling, which had no effect.

 

My environment:

Win 2012 R2 Server

Logfile is kept open by the writing process all the time

 

Here u can see it compared to another editor, same log at the same time, new lines are missing.

If I refresh, then its fine

 

mit freundlichen Grüßen | kind regards

Hi Gerald,

Same problem here. I use glogg to show logfiles created by a Java application using Log4J.

I discovered, that, even after new log entries are written, the modification time of the logfile did not change.

If I manually added some entries using a text editor, the modification time of the logfile was updated and

also immediately displayed by glogg!

I suppose, glogg looks at the modification time of the observed file and, if  it does not change, glogg

will not update its view.

regards

Roland

Hi, same here.

Using a file on local disk definitely currently being filled by another process, glogg just sits there and doesn't see the changes, only after hitting 'refresh'. I didn't verify your observation regarding file modification time though.

I have had this same problem since before 2014. It seems that windows support is trivial and of no interest. A log viewer should be able to follow or it is virtually no different from Notepad.

Hi glogg users,

As we use our own log4j appenders here (RollingThreadingZipFileAppender, which zips the rolled log files),

I was able to solve the problem by updating the file modification date on every append.

The code of the RollingZipFileAppender looks like this:

public class RollingThreadingZipFileAppender extends RollingFileAppender {

  :

  :

    @Override

    public void append(LoggingEvent event) {

        super.append(event);

        updateModificationTime();

    }

    /**

     * Updates the log file modification timestamp.

     * Some log file viewers (e.g. glogg) relies on the file modification date to detect

     * file changes.

     */

    private void updateModificationTime() {

        if (logFile == null)

            logFile = new File(fileName);

        logFile.setLastModified(System.currentTimeMillis());

    }

}

Hope this helps.

Updating the file modification time keeps glogg up-to date with new records in the log file.

Another annoying problem (at least on Windows OS) is, that the files are locked by glogg, so they can not be deleted while glogg is open (no problem with baretail for example).
