I have long log files from multi-threaded multi-program simulations
that output this sort of thing:
> BUS:16:15:35.212525 vme:082a4000 \
irqn: opening shared memory object /var/tmp/vmedir/irqn.bus
> BUS:16:15:35.221792 vme:082a4000 \
irqn: Master opening request FIFO blocking.
> BUS:16:15:37.193684 foo:082a4000 \
irqn: opening /var/tmp/vmedir/irqn.bus
> BUS:16:15:37.194125 foo:082a4000 \
irqn: Opening /var/tmp/vmedir/irqn.request write-only...
> BUS:16:15:37.194318 vme:082a4000 \
irqn: blocking for request
> BUS:16:15:37.194524 foo:082a4000 \
irqn: creating reply fifo /var/tmp/vmedir/irqn74193.74181.reply
> BUS:16:15:37.194771 foo:082a4000 \
irqn: writing request #0 "Attach" (with handshake, sem 0x830f5e0 pSem 0xbfbfe3dc) to request FIFO.
> BUS:16:15:37.195009 vme:082a4000 \
irqn: received request #0 (with handshake) "Attach" from client foo
I'd like to be able to graphically browse these logs so that unusual sequences
jump out. There are time stamps, programs, thread ids, etc, in the fields
and I want to plot them along the time axis with different colors,
different programs at different heights, etc.
I did a little searching for log file analysis, etc, but only see
web site oriented utilities. I'll start rolling my own using a tk
canvas, but does anyone know of a good starting point tool?
