If you're intereted in doing some analysis yourself, I just modified the
log-processing code to give you something more easy to work with.
Using log-processing >= r2365 will let you say:
swift-plot-log 066-many-20081210-0834-xk5h3us8.log info.event
(i.e. add info.event onto the end of the command line)
This will give you a file info.event (in a directory under /tmp indicated
at the end of the command output) with one line per info file, that looks
like this:
1228919959.621686561 0.288390398025513 touch-0cej8i3j END touch
The fields are space separated and are, in order:
1. start time in seconds since epoch
2. time of wrapper script execution on worker node
3. job id
4. final wrapper script status
5. application name
You can use this information now if you want to do your own further
analysis, or you can wait for me to implement per-app stats (that will
likely look like the per-site stats that appear at the end of
execute2.html in a log report).
