[Swift-devel] Swift and BGP plots

[Ioan Raicu]

OK, so this looks to be a bit more complex then. Can you suggest a way 
to extract the Active and Complete timestamps (along with the task ID)? 
It seems that if I grep for JOB_SUBMISSION, the status Active is not 
found on the same line, so I can't filter according to those two 
keywords. Also, the Completed keyword also comes up with many other 
hits. Any ideas on how to get the info I need (with cat, grep, etc) 
without writing some custom script/program that actually understands in 
depth the logging of the Swift log?

Thanks,
Ioan
