Munin : Correction de problèmes sur les plugins mysqls

Sun, 19 Jan 2025 00:00:00 +0000

Pour tester manuellement j’ai fait :

/usr/sbin/munin-run --debug mysql_
/usr/sbin/munin-run --debug mysql_isam_space_

j’ai pu voir qu’il me manquait des installations en Perl

apt-get install -y libcache-cache-perl
apt-get install libdbd-mysql-perl
apt-get install libgd-gd2-perl
apt-get install libgd-graph-perl

Raspberry : Munin : les graphiques de la Freebox après un mois

Tue, 30 Oct 2018 00:00:00 +0000

Pour faire suite : https://www.cyber-neurones.org/2018/09/raspberry-munin-les-premiers-graphiques-de-la-freebox/ .Raspberry : Munin : les premiers graphiques de la Freebox.

Voici les graphiques après un mois :

En ce moment, je suis en mode : Misère (il suffit de voir :Freebox status). Et comme toujours le support n’est pas joignable …

La première étape est de voir si le Bluetooth est bien lancé au démarrage :

A noter pour que cela fonctionne bien j’ai du ajouter le service hciuart :

Munin pour Android : l'application est basique mais elle fonctionne.

Voici le lien vers l’application : https://play.google.com/store/apps/details?id=com.chteuchteu.munin&hl=fr . J’ai du mal à voir la valeur ajouter si l’on compare avec un simple navigateur Web. Mais cela fonctionne ….

Munin/Raspberry : Correction à faire ?! ( irqstats, snmp_admin_swap, acpi )

Wed, 03 Oct 2018 00:00:00 +0000

Quand je regarde les logs j’ai :

 Error output from irqstats:
     Argument "usb_fiq" isn't numeric in addition (+) at /etc/munin/plugins/irqstats line 95, <$in> line 18.

Le code en question qui pose problème :

sub sum (@) {        
    my $sum = 0;
    $sum += $_ || 0 for @_;     # Avoid complaints about empty strings
    return $sum;                                                     
}

Je viens de voir qu’il y avait un fix : http://munin-monitoring.org/attachment/ticket/1462/munin-v2.0.6-raspberry_pi-irqstats-usb_fiq.patch fait le 01.04.2014 ?!

OSMC/Raspberry : installation de munin ( et Apache2) avec un script pour Freebox

Wed, 19 Sep 2018 00:00:00 +0000

Le script pour la freebox est ici : https://github.com/guyou/freebox_munin/blob/freeboxv5/freeboxv5 ( le projet est http://github.com/d-matt/freebox_munin ) .

Pour plus d’information sur Munin : https://doc.ubuntu-fr.org/munin ( A noter qu’il faut Apache2 afin de voir l’interface ) .

L’installation :

$ sudo apt-get install munin
$ sudo apt-get install munin-node
$ sudo apt-get install munin-plugins-extra libcgi-fast-perl libapache2-mod-fcgid
$ sudo apt-get install apache2
$ sudo apt-get install libapache2-mod-php5 apache2-doc apache2-utils
$ sudo ln -s /etc/munin/apache24.conf /etc/apache2/conf-available/munin.conf
$ sudo a2enmod fcgid
Enabling module fcgid.
To activate the new configuration, you need to run:
  service apache2 restart

$ sudo systemctl restart apache2
$ sudo su
