NAME

SYNOPSIS

flow-split [ -gGhn ] [ -b big|little ] [ -C comment ] [ -d debug_level ] [ -N nflows ] [ -o outfile_basename ] [ -T nseconds ] [ -z z_level ]

DESCRIPTION

The flow-split utility will split a flow file into smaller files based on the the number of flows or the ammount of time that has passed.

OPTIONS

-b big|little

Byte order of output.

-C Comment

-N nflows

-T nsecond

Split after processing an interval of nseconds flows.

-z z_level

Configure compression level to z_level. 0 is disabled (no compression), 9 is highest compression.

EXAMPLES

Create 1 minute flow files from the flow archive in /flows/krc4. Store the results in /flows/krc4.split

flow-cat /flows/krc4 | flow-split -T60 -o /flows/krc4.split/1min.
