Log file viewer /analyser

Smoggy

I'm looking for options for a log file viewer / analyser. At te moment in using notepad, so I'm feeling pretty behind te curve and that there is a whole world of options out there ths I'm unaware of.

What I would like is :

Ability to handle large files.
Handle multiple files (maybe of different formats) in the same viewer
Load data on the fly, so as more logs are added to the file the viewer is refreshed.
Search and filter options, by bug or freetext search etc.
Ideally open source, so I can add features that might be missing.

So, what are you guys using ?

tail -f/grep/less :P

Edit: Though that Wintail looks pretty decent.

If you're looking at logs generated by log4j (or similar clones like log4n, etc.) I've recently found Otros Log Viewer, and while it doesn't necessarily offer much for many tech-savvy users, it has a few nice features, e.g. thread filtering, etc. and it can do this over SCP to a remote *nix server. You can tailor the filters to match your own log layout as well if it's non-standard.

I only use it occasionally myself, but some of the other users I've introduced to it are very happy.

Wintail for viewing log files that may update as you are watching them.

Windiff for seeing the difference between two files.

For everything else, vi. :pac:

LogParser2 from MS is very handy.

You can write sql like queries against most log file types, csv etc

robocode

You could use something like elasticsearch/logstash to handle your logs and then kibana to view/query them. A nice solution, albeit perhaps overkill.

If you're on *nix, use a combination of tail, grep, sed

If on Windows, download git-bash and use a combination of tail, grep, sed

If on MacOS, use a combination of tail, grep, sed

Thanks for te suggestions, I will take a look through them.

I think we will be going the log4net route, meaning the likes of Otros could work well.

Logexpert. Everything baretail is and more. I can't live without it! Filtered searches tailed in their own tab and a custom columnizer. Really good and free too :-)

Log4View is quite good.
