Hi, I'm looking for a simple IIS Log Viewer that can open large (e.g. 100 meg) IIS Log files and give me simple filtering and searching tools.
(IIS = Microsoft Internet Information Server, obviously)
(OK, I know I could use Notepad, but I'd like something that can help me filter out the bits I'm not interested in)
You should check out LogParser:
Update: I should add that LogParser is blindingly fast we parse (checking for all sorts of stuff) around a gig of logs a day per server on the shared platform and it just rips through them.
It also has a COM API so you can write your own parsing tools to suit your needs (something we do as well).
Visual Log Parser works really well for more than just IIS logs too.
While it doesn't do much in the way of filtering and it definitely isn't a parser; a really useful tool for your toolbelt is a (free-ware) real-time log file monitoring tool called BareTail.
You open up a log file in BareTail and it 'follows' the very end of the file in real time as text gets continuously written/appended to the end of the file.
Lines containing particular strings can be highlighted to help you notice important text as it flies by (you can pause the 'follow' behaviour if you see something useful).
Hmmm. This is an old question (before I got here) and I'm surprised no one mentioned Analog. http://www.analog.cx/
The two criteria you ask for, i.e. Open large log files and simple filtering and searching tools fit Analog to a tee.
