# flow-log2rrd(1)

Process the STAT: lines from flow-capture and flow-fanout to RRD files.

## NAME

**flow-log2rrd** — Process the STAT: lines from **flow-capture** and **flow-fanout** to RRD files.

## SYNOPSIS

**flow-log2rrd** \[-p *rrd\_path*\]

## DESCRIPTION

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.

## EXAMPLES

Convert flow-capture STAT lines in /var/log/netflow to RRD's in /flows/rrd/.

    **cat /var/log/netflow \| flow-rpt2rrd -p /flows/rrd**

## BUGS

Expects STAT lines every 5 minutes.  Hard coded to 7 days of 5 minute averages and 365 days of 1 day averages.
