DM SysLog Monitor

DM SysLog Monitor is a feather-light and portable application that listens for data on port 514 via UDP, which is the standard port for message logs.
The firewall might ask for permission to use this tool. You can use it to analyze the SysLog messages transmitted by the router to your computer, for example, in order to identify and troubleshoot possible issues.

Portable utility with a simple UI

There is no installation involved, which makes this app portable. This means that you can drop its .exe file in any part of the hard disk or a removable storage unit, in order to launch it on any machine effortlessly. It doesn't change any settings in your Windows registry.
As far as the interface goes, DM SysLog Monitor adopts a plain and simple window with a straightforward look, where the SysLog messages transmitted by your router should be immediately loaded at startup.

Analyze and capture SysLog messages to file

Details include the sender's IP address, timestamp, port number and description of each event. This information can be automatically saved to CSV files as soon as it's captured, if you tinker with this setting in the options panel beforehand.
Apart from the fact that you can clear the console, disable auto-scroll for large-sized messages, and hide the events from the console window, there are no other noteworthy options available.

Evaluation and conclusion

We haven't found any unpleasant surprises in our tests as far as OS compatibility is concerned, since the program didn't freeze, crash or prompt error dialogs. As expected, its impact on the computer's performance in our tests was barely noticeable.
Taking everything into account, DM SysLog Monitor turns out to be a simple and effective tool for monitoring SysLog messages, and it can be easily handled by anyone.
