Is there a tool out there that allows you to filter lines into different windows (or remove them altogether) so that I can separate the output of the various logging sub-systems and remove spam messages that show up multiple times a second?

I'd prefer an open-source solution, but a highly-recommend closed product might do.

I've never thought of doing such a thing, but here's one product that might do the trick: Eltima Serial Port Splitter. It claims to be able to take one COM port and turn it into multiple virtual ports to connect to many applications. You might be able to take each application and just look at one kind of output.

Personally, I would just write a python script with PySerial and something like PyQT or wxPython (GUI libraries) to filter the data to different windows. It's an easy language to learn and makes a handy tool for embedded systems development for things such as this.

I would do the following:

Use Python.

• Use Python's logging module
• Use 3rd-party pySerial module

Write a Python program to read the serial data from the device, and translate it into log item for Python's logging module.

• If your device's log messages have some sort of source identifier, translate that to a Python 'logger' name according to your needs, using the getLogger() function. You can define logger names any way that you need, e.g. to define log source or category.
• If your device's log messages have a severity indication, translate it to the lvl parameter to the logger's log() method. Otherwise just use one of the logger methods such as info().

Make use of the Python logging module's config file feature to filter the data as you want in a particular situation.

• You can filter particular log items by severity and logger name.
• You can log to multiple destinations: You can filter and print certain log items to screen, and at the same time filter and print certain log items to one or more files. You can mix these in any combination that you want. It's very flexible.
• You could have several logging config files, for several different logging purposes, and simply specify which one you want to use via the command line each time you run your program.

I've used Python's logging module with config files to set up my filtering, and it's really terrific.

You can use the Eltima's splitter with Advanced Serial Data Logger, this software has several filter plug-ins that can filter out unnecessary messages.

I guess it will depend on the format your logs have. If they looks like (or you can make them look like) the syslog format, you can try the following:

I would personally use the Python method described above, but another (relatively easy) way to go about it would be to use sed.

Build a couple different filters to show precisely what you want from the stream, and then pipe in tail -f of your serial device file.

SmarTerm allows you to connect to many different serial ports in a tabbed interface. It also has a Visual Basic like scripting language that allows you to write scripts for different needs. I wrote quite a few scripts for updating embedded software and also automating the saving of logs in multiple tabs.

Serial Port Data Logger

Try Powershell. You obviously need to add filtering, but this should get you started

My first choice is to always run PortMon (originally from SysInternals). It has a filter option where you can type in strings to include, exclude, or highlight:

I have used this for years on Windows NT/2000/XP with great success.

Hopefully, you're running a 32-bit Windows OS, because if you're running 64bit, you'll have to go with something like Eltima's product.

There's always the venerable protocol analyzer.

You might only get one color on the screen, but it's a platform independent serial port logging solution.

Today, computer viruses have literally flooded the world and continue moving freely around the Internet. Now, when we hear the word “port”, the first thing that comes to our minds is logical ports that are used in network technologies like TCP/IPor UDP to organize communication channels, but we forget about physical ports serving for connecting external devices. High-speed USB interfaces are now seen as a universal means for connecting printers, mice and keyboards, whereas good old COM ports are used less frequently. However, the latter ones are still present in some modern computers, and probably the time has come to use them for some other purposes, for example, for controlling specialized COM-based equipment.

In order to monitor and analyze serial communications between a computer and a COM port device, you can rely on a dedicated software - serial data logger which will read and record RS232 data to a text file for its further analysis.

There are also special hardware RS232 port analyzers designed to capture analog and digital signals but, like any professional equipment, they are rather expensive to buy.

In this article, I’ll cover both software and hardware COM port loggers and highlight the clear benefits you get with one or another solution. Read on to learn how to capture serial port data to file in the fastest and simplest way.

Arduino serial data logger

Want to find out how to build an Arduino data logger and watch data from an Arduino? Here’s a quick way to do this:

If you can use an SD card in your project, that is an obvious solution to create an Arduino SD card data logger. Some Ethernet shields are provided with an SD Card reader. Or you can add an SD card by using a microSD adapter.

It won’t be difficult to interact with your SD card from an Arduino, as SD cards use a form of the SPI protocol. You only need to make sure it is a slower class. A proven way is to use Class 4 cards and make sure then are 16GB or less.

The IDE comes with an SD Example called “Datalogger”, so you can find a code example there.
