Onderwerp: MRTG en DNS

ik was ooit is begonnen aan iets met perl/tail en rrdtool.

die pakt gewoon de /var/log/named/queries.log waar alle queries naar gelogd worden.

dns.pl:

Code:

#!/usr/bin/perl

use strict;


# Set files to use, change these to suit your needs
my $oldstatfile = "/var/tmp/dns-old.txt";
my $newstatfile = "/var/named/named.stats";


# Obtain old DNS stats from stored file
open(OLDF, "$oldstatfile");
my @raw_data = <OLDF>;
close(OLDF);

my $oldsuccess = @raw_data[0];
my $oldfailure = @raw_data[1];

chomp($oldsuccess);
chomp($oldfailure);


# Check if there is data, if not, initialize
if (! $oldsuccess) {
    $oldsuccess = 0;
}

if (! $oldfailure) {
    $oldfailure = 0;
}


# Get new data from file, first clean the stats file and dump new
system("cat /dev/null > $newstatfile");
system("/usr/sbin/rndc stats");
open(NEWF, "$newstatfile");
my @dns_data = <NEWF>;
close(NEWF);

my $newsuccess = 0;
my $newfailure = 0;
my $line;
my $foundsuccess = 0;
my $foundfailure = 0;


foreach $line (@dns_data) {
    if (($line =~ /^success ([0-9]*)/) && ($foundsuccess == 0)) {
        $foundsuccess = 1;
        $newsuccess = $1;
    }

    if (($line =~ /^failure ([0-9]*)/) && ($foundfailure == 0)) {
        $foundfailure = 1;
        $newfailure = $1;
    }
}


# Calculate difference between old and new. Divide by 5 to get per minute
my $diffsuccess = ($newsuccess - $oldsuccess) / 5;
my $difffailure = ($newfailure - $oldfailure) / 5;


# Store new data

# Print difference

Nivko, zou jij misschien al je plugins voor mrtg willen share met mij? Ik ben er onder de indruk namelijk



De mijne namelijk:

Tuurlijk

Misschien niet geheel ontopic maar vanaf deze post worden er door mij en Randy (ook aanwezig op dit forum) nog een aantal extra checks beschikbaar gesteld:

Om je mrtg stats wat op te vullen

Die extra's zijn van Randy die in mijn configs staan

Had deze ook al. Echter heb ik wel enkele aanpassingen gedaan om de juiste gegevens op te halen.

Code:

if [ "$TYPE" = "pop3" ]; then
    INDATA=`cat /var/log/maillog | grep pop3-login | grep "$(date --date='1 minutes ago' +'%b %_d %R')" | wc -l`
    OUTDATA=$INDATA
fi
    
if [ "$TYPE" = "imap" ]; then
    INDATA=`cat /var/log/maillog | grep imap | grep "$(date --date='1 minutes ago' +'%b %_d %R')" | wc -l`
    OUTDATA=$INDATA
fi

Zo krijg ik alle gegevens van de laatste minuut en ook maar 1x per login en niet per lijn dat over imap of pop3 gaat.

Nivko, bij mij doen de DNS Stats het niet, enig idee hoe dat komt?

En als ik krijg de volgende error als ik handmatig cronupdate:

Enig idee?

Bestaat er wel een named.stats? Probeer eens 'rndc stats'

[***@***]# rndc stats
bash: rndc: command not found

[***@***]# locate named.stats
Krijg ik niks

Enig idee?

Draai je geen bind? Probeer is 'locate rndc' ?

[**@** **]# locate rndc
/usr/share/man/man5/rndc.conf.5.gz
/usr/share/man/man8/rndc-confgen.8.gz
/usr/share/man/man8/rndc.8.gz
/usr/sbin/rndc
/usr/sbin/rndc-confgen
/etc/rndc.key
/etc/rndc.conf

Dan doe je:

/usr/sbin/rndc stats && updatedb

Dan kijk je daarna dmv. locate named.stats waar named.stats staat, die locatie zet je in dns.pl en dan ben je klaar!

Hmm, toch iets raars want als ik dit doe:

/usr/sbin/rndc stats && updatedb

En dan vervolgens:

locate named.stats

Vind hij niks? Weer enige ideen?
