| Running vnstat on OpenBSD
+-------------------------------------------------------------------------------

1) Edit /etc/vnstat.conf if necessary.

2) Start the vnstatd daemon:
    # rcctl start vnstatd

3) Run "vnstat --iflist" to see all the available interfaces.

4) For each interface to be monitored, launch this command:
    # su -m  _vnstat -c  "vnstat --add -i INTERFACE"
This will create the database for the specified interface. Otherwise,
adjust "Interface" in /etc/vnstat.conf.

5) Create graphics with the command "vnstati". (Install the vnstati
package with "pkg_add vnstati".)

Random hints:
    * "UseLogging" in /etc/vnstat.conf enables logging.
      "UseLogging 1" uses /var/log/vnstat/vnstat.log
      "UseLogging 2" uses syslog.
