Configuration

Exemple de pfstat.conf pour afficher la bande passante utilisée:

collect 1 = interface "bnx0" pass bytes in ipv4 diff
collect 2 = interface "bnx0" pass bytes out ipv4 diff

image "/var/www/htdocs/pfstats/bnx0.jpg" {
        from 1 days to now
        width 980 height 300
        left
                graph 1 bps "in" "bits/s" color 0 192 0 filled,
                graph 2 bps "out" "bits/s" color 0 0 255
}

image "/var/www/htdocs/pfstats/bnx0-week.jpg" {
        from 1 weeks to now
        width 980 height 300
        left
                graph 1 bps "in" "bits/s" color 0 192 0 filled,
                graph 2 bps "out" "bits/s" color 0 0 255
}

image "/var/www/htdocs/pfstats/bnx0-month.jpg" {
        from 1 months to now
        width 980 height 300
        left
                graph 1 bps "in" "bits/s" color 0 192 0 filled,
                graph 2 bps "out" "bits/s" color 0 0 255
}

On lance ensuite les crons suivants :

# crontab -l

*   * * * *    /usr/local/bin/pfstat -q # Met a jour la base RRD
*/5 * * * *  /usr/local/bin/pfstat -p # Trace les graphs

Une petite page HTML pour rendre la consultation plus facile :

<html>
<h1>PFStats</h1>
  <h2>bnx0</h2>
    <h3>Today :</h3>
    <img src="bnx0.jpg"/>
    <h3>Last week :</h3>
    <img src="bnx0-week.jpg"/>
    <h3>Last month :</h3>
    <img src="bnx0-month.jpg"/>
</html>
