analysis

this seems to be a reoccurring issue: we receive a bug report for our software and with it tons of traces or logfiles.
since finding errors is much easier when having a visualization of the log messages/events over time it is convenient to use a tool that can display the progression of events in a graph etc. (e.g. wireshark (http://www.wireshark.org) for analyzing network traffic)

what tool do you use for such a purpose?

the problem with most tools i used so far is that they mercilessly break down when you feed them huge data traces (> 1GB) so some criteria for such a tool would be:

can deal with huge input files (> 1 GB)
is really fast (so you don't have to get coffee while a file is loading)
has some sort of filtering mechanism
