flow-log2rrd(1) General Commands Manual flow-log2rrd(1)NAME
flow-log2rrd -- Process the STAT: lines from flow-capture and flow-fanout to RRD files.
flow-log2rrd [-p rrd_path]
The flow-log2rrd utility processes the STAT lines generated by flow-capture and flow-fanout and converts them into RRD files. RRD's are
stored as rrd_path/capture|fanout.hostname.srcip.dstip.port.rrd. The Datastores are flows,pkts,lost representing flows, packets, and lost
flows respectively. Flow-fanout generates an additional DS nobufs indicating the number of times a write() failed with ENOBUFS.
OPTIONS -p rrd_path
Path to store files.
Convert flow-capture STAT lines in /var/log/netflow to RRD's in /flows/rrd/.
cat /var/log/netflow | flow-rpt2rrd -p /flows/rrd
Expects STAT lines every 5 minutes. Hard coded to 7 days of 5 minute averages and 365 days of 1 day averages.

flow-cat -- Concatenate flow files
flow-cat [-aghmp] [-b big|little] [-C comment] [-d debug_level] [-o filename] [-t start_time] [-T start_time] [-z z_level]
The flow-cat utility processes files and/or directories of files in the flow-tools format. The resulting concatenated data set is written
to the standard output or file specified by -o. If file is a single dash (`-') or absent, flow-cat will read from the standard input.
OPTIONS -a Do not ignore filenames that begin with tmp.
Byte order of output.
Add a comment.
-g Sort file list by capture start time before processing.
-h Display help.
-m Disable the use of mmap().
-p Preload headers. Use to preserve meta information such as lost flows.
-o file Write to file instead of the standard out.
Select flow files up to start_time. If used with -T select files between start_time and end_time.
Select flow files after end_time. If used with -t select files between start_time and end_time.
Configure compression level to z_level. 0 is disabled (no compression), 9 is highest compression.
Process the files and/or directory.
TIME /DATE parsing
start_time and end_time parsing is implemented with getdate.y, a commonly used function to process free-form time date specifications.
Example usage borrowed from cvs:

Concatenate all flow files begining with ft-v05.2001-05.01, use flow-print to display the results.
flow-cat ft-v05.2001-05-01.* | flow-print
Concatenate flow files in /flows/krc4, store store the output in compressed.flows at compression level 9 (best). The headers are preloaded
so various metadata such as the flow count is correct in the result. Filenames begining with tmp which are typically in-progress flow
files from flow-capture are not processed.
flow-cat -p -z9 /flows/krc4 > compressed.flows
