[Nfdump-discuss] fetch flow records from last 'n' seconds

[Javier L. <ja...@li...>]

i'm sorry if this have been discussed before, but my google-fu only
goes so far...i even tried to read the source files to no avail...way,
way, way above my skillset :(

what i'm trying to do is to list all the flows from the last 'n'
seconds...man pages says that i can use the '-t' option with a '-n' or
'+n' to do this, but for the life of me i have not been able to do
it...

some examples of what i have tried are:

nfdump -R /nfsen/data -t -60
Time Window error: No time slot information available

nfdump -R /nfsen/data -t 2013/07/19.-60
Time format error: '' unexpected.

Time format error: '60' unexpected.

nfdump -R /nfsen/data -t 2013/07/19-60 <<<<--- no dot
Time format error: '60' unexpected.

i'm looking for examples to do this...

regards,

javier
