Add multline separation

[RegulumDreik]

Hello! I am very interested in this application. But I got a problem when using it with multi-line logs. It is not possible to adequately separate messages with more than one line in them. In filebeats, as far as I know, it is possible to write a pattern for dividing the log into messages. For further analysis. I would like to see similar functionality here.

Could you attach an example of the multiline log?

That is, the log contains time, technical information, and an XML message.
I parsed this messages by regexp, but regexp not fill timestamp.

Yes, it's possible to separate messages correctly. You have to specify the format of the log manually in log-viewer-0.1.5/config.conf. There is logs = [ ... ] section that lists available logs and its format. Add the following lines here

    {
        path: "/my-app/logs/filename.log"
        format: {
            type: Log4jLogFormat,
            pattern: "[%d{dd.MM.yy HH:mm:ss.SSS}]\t%m%n"
        }
    }

Don't forget to replace "/my-app/logs/filename.log" with the path to your log location.

The result will look like

logs = [
  {
    path: "**/*.log"  // All files with ".log" extension are visible by default
  }
  {
    path: "**/*.log.*"  // All files like "*.log.1" are visible by default
  }
  {
    path: "/my-app/logs/filename.log"
    format: {
      type: Log4jLogFormat,
      pattern: "[%d{dd.MM.yy HH:mm:ss.SSS}]\t%m%n"
    }
  }
]
