flowctl8

Ng_netflow(4) control utility

Usage

flowctl [-d level] path command

Overview

The flowctl utility is intended to control the ng_netflow(4) nodes. It has a single option:

-d level

Set the netgraph(3) debugging level to level.

Commands

Currently, flowctl supports only one command.

show [ipv4|ipv6] [human|verbose]

This command is the analog of the “show ip cache flow” command of a Cisco router. It dumps the contents of the flow cache in Cisco-like format. Specifying either ipv4 or ipv6 would extract only IPv4 or IPv6 flows respectively. It has optional parameter verbose, which is analog of the “show ip cache verbose flow” command. Additionally, human parameter can be specify to show selected flows in human-readable format.

Exit status

The flowctl utility exits 0 on success, and >0 if an error occurs.
