Sometimes I need to watch a log file or other file for changes, whether it be on my local machine or a remote server. On windows this can be a bit of a pain, and you oftentimes have to dump out of your IDE to make it happen.

So on a whim one day, I said “I wonder if VS Code can do that”. I search the extensions, and lo and behold, VS Code can do that!

Enter VS Code and the Log Viewer Extension

Open VS Code
Click on the Extensions button
Type Log Viewer in the search box
Find the Log Viewer Extension and install it.

Setting up the Extension

In VS Code, open the Command Bar (for me, CTRL + Shift + P does this)
Type Workspace Settings or similar and then select Preferences: Open Workspace Settings
In the settings, add a section for logViewer.watch that defines some titles and patterns for files that you’d like to watch. Below is an example of watching two separate files on different servers. I add the below and save my preferences:

{
    "logViewer.watch": [
        {
            "title": "Server 1 IIS",
            "pattern": "\\\\servername\\C$\\inetpub\\logs\\LogFiles\\W3SVC2\\u_ex180718.log"
        },
        {
            "title": "Server 2 IIS",
            "pattern": "\\\\servername2\\C$\\inetpub\\logs\\LogFiles\\W3SVC2\\u_ex180718.log"
        },
    ]
}

What are the Results?

The log viewer opens a screen, and we can see all the applicable watches and view their updates as they change.

I love that I can define patterns and not just file paths, so that I can watch multiple files at once.
