This document will show how to configure pmacct for IP accounting. Pmacct will be configured as NetFlow and sFlow collector using PostgreSQL as DB backend.

The following software have been used at the time of writing of this document:

* pmacct-0.12.4-r3
* postgresql 8.4

Install and Configure pmacct

apk add pmacct pmacct-doc

On postgreSQL server launch the following scripts found in /usr/share/doc/pmacct/sql (make sure to change the default password for user "pmacct" in pmacct-create-db.pgsql):

postgres$ psql -d template1 -f pmacct-create-db.pgsql
postgres$ psql -d pmacct -f pmacct-create-table_v7.pgsql

NetFlow Collector Daemon

Edit /etc/nfmacctd.conf, changing "<HOSTNAME>" and "<PASSWORD>" to correct values:

daemonize: true
pidfile: /var/run/nfacctd.pid
syslog: daemon

sql_host: <HOSTNAME>
sql_passwd: <PASSWORD>
sql_table_version: 7

plugins: pgsql

sql_optimize_clauses: true
sql_recovery_logfile: /var/log/nfacct_recovery_log
sql_history: 5m
sql_history_roundoff: mhd
sql_dont_try_update: true

aggregate: src_host,dst_host,src_port,dst_port,proto
