<p>I'm looking for non-web-based tools to view IIS logs.  I've been using <a href="http://www.microsoft.com/technet/scriptcenter/tools/logparser/default.mspx" rel="nofollow noreferrer">LogParser</a> but I was hoping for something with an interface.  It doesn't need to do any fancy reports or charts -- just a list with some search filters is plenty.  I need something lightweight that I can run directly on the web server, preferably without a complex install process.</p>

I find that command-line tools are often enough. For example, to list all log entries with a 404 response:
```
```
findstr "404" logfilename > out.txt
```
```
Findstr supports regular expressions in the search term and wildcards in the filename, so it is quite flexible for dealing with logfiles.
