MonitorPi – Nagios, Centreon, Check_MK, Nagvis auf dem Raspberry Pi 2

raspberry-pi-2-770x577Es ist mal wieder so weit, es gibt ein Update in Sachen Monitoring. Viele kennen mit Sicherheit den kleinen Raspberry Pi, eigentlich als dritte Welt-PC gedacht – aber unter den Bastlern ebenfalls ein Hit geworden. Ich habe ja schon mehrere Beiträge zum Pi hier geschrieben, aber seit dem Raspberry Pi 2 gibt es noch ganz andere Anwendungsfelder die durch die größere Leistung möglich werden.
So auch das Projekt „MonitorPi“, dass den RaspberryPi in eine Überwachungszentrale verwandelt, die inklusive Zubehör preislich auch unter 100€ liegt.
MonitorPi ist eine fertige Appliance von mir – die mit den beliebtesten Monitoring-Tools vorinstalliert ist.
Was ist alles enthalten und vorinstalliert ? (Ready 2 use)
– Nagios 3.5.1 Nagios
– Centreon 2.6.0centreon_logo
– Centreon-Broker 2.8.2
– Check_MK (Livestatus) 1.2.6.p2check_mk.200
– Nagvis 1.8.2
– Nagios Plugins 2.0.3nagvis
Was wird benötigt ?
Raspberry Pi 2
– mind. 8 GB Speicherkarte (Je schneller desto besser. Class 10 = top)
Win32DiskImager
[stextbox id=“info“]MonitorPi basiert auf der aktuellen Debian Wheezy Distribution die es auch via raspberrypi.org zum Download gibt. (2015-02-16-raspbian-wheezy.img)
Nur habe ich sie noch vollständig aktualisiert. Stand: 04.05.2015[/stextbox]
Wie wird MonitorPi installiert ?
Ganz einfach: Ihr ladet euch die aktuelle Image-Datei herunter und bespielt diese auf eine micro-SD-Karte.
Dies geht mit dem Win32DiskImager wie im Bild beschrieben:
win32diskimager
 [stextbox id=“alert“]Achtung: Alle Daten auf der SD Karte werden gelöscht![/stextbox]
Anschließend den Rasperry Pi 2 mit der SD-Karte booten, er versucht automatisch eine IP via DHCP zu beziehen, und zeigt diese nach dem Boot an.
Wie sehen die unterschiedlichen Monitoring-Tools aus ?


Wie erreiche ich die Tools ?
Alle Tools sind Web-Applikationen, die per Browser aufgerufen werden. Die Url’s sind wie folgt:

FAQ:
Warum ist nicht Nagios 4 installiert?
Zum einen gibt es noch die ein oder anderen Kompatibilitätsprobleme mit Centreon, wer auch noch andere Module benutzen möchte, stößt eventuell ebenfalls auf Kompatibilitätsprobleme. Wer dennoch aktualisieren will kann das natürlich gerne tun.
Wo liegen die Quelldateien ?
Alle Quelldateien liegen unter /home/pi/sources.
MonitorPi-Sources
Wo liegen die wichtigsten Programme ?
Ich habe die Anwendungen in der Regel immer mit Standardwerten kompiliert. Aber hier einige Pfade:
Nagios: /usr/local/nagios
Nagios Plugins: /usr/local/nagios/libexec
Centreon: /usr/local/centreon/

Raspberry Pi als Nagios Poller installieren und in Centreon aufnehmen

300px-RaspberryPiEin kleiner Raspberry Pi bietet sich ja quasi als Nagios Poller an, wenn man ein kleines, günstiges und stromsparendes Gerät zum Überwachen von Servern, PC’s,  Druckern, oder vielem mehr sucht.
Ich beschreibe hier wie man einen zweiten Nagios-Server in eine bestehende Nagios / Centreon Umgebung aufnehmen kann. Wie man Nagios bzw. auch mit der wesentlich einfacheren Konfigurationsoberfläche Centreon installieren kann habe ich bereits beschrieben. Da hat sich bis auf ein paar Versionsnummern auch nichts verändert. Daher verweise ich an den passenden Stellen auf meinen alten Beitrag.
Wer einfach nur Nagios auf einem Raspyberry installieren will, kann hier auch einfach bis Punkt 2 folgen. Einfach am Ende Centreon nicht mitinstallieren.
Als Grundsystem für den Raspberry wird wegen der Einfachheit ein Debian RAW-Image verwendet. Dieses könnt ihr euch hier herunterladen: http://www.raspberrypi.org/downloads
Achtung: Die NDOUtils funktionieren nicht im Zusammenspiel mit dem „hard float“ Raspberry Image. Wenn ihr die NDOutils einsetzt müsst ihr die „Soft-float“ Debian Version verwenden.
(Ich verwende noch die NDOutils!)

Bis auf die Abhängigkeiten ist fast alles identisch zur normalen Installation von Nagios – wie ich es schon hier beschrieb.
1. Abhängigkeiten Installieren

apt-get install apache2 libapache2-mod-php5 build-essential libgd2-xpm-dev mysql-client gcc make g++ lsb-release libssl-dev

2. Nagios + Plugins herunterladen und installieren
Könnt ihr aus dem Beitrag hier entnehmen: https://constey.de/2012/06/how-to-install-nagios-centreon-nagvis-check_mk-ubuntu-12-04-server/
(
Wenn man nur Nagios installieren will, ohne Centreon – ist man hier fertig.)
3. Zusätzlichen centreon Benutzer anlegen
Da der Centreon Central Server mit dem User centreon arbeitet, und diesen auch für den Austausch von Config-Dateien etc. verwendet, muss dieser auch hier angelegt werden.

/usr/sbin/useradd -m -s /bin/bash centreon
passwd centreon

4. Noch den Centreon User in die Nagios Gruppen aufnehmen

/usr/sbin/usermod -G nagcmd centreon
/usr/sbin/usermod -G nagios centreon

5. SSH Authentifizierung per Keyfile einrichten & in Centreon aufnehmen
Haltet euch hier an die Doku von Centreon. Diese ist sehr gut, und bebildert.
http://en.doc.centreon.com/DistributedArchitecture
In der Sudo Konfiguration muss der centreon Benutzer ebenfalls analog dem nagios Benutzer berechtigt werden:

centreon   ALL=NOPASSWD: /etc/init.d/nagios restart
centreon   ALL=NOPASSWD: /etc/init.d/nagios stop
centreon   ALL=NOPASSWD: /etc/init.d/nagios start
centreon   ALL=NOPASSWD: /etc/init.d/nagios reload
centreon   ALL=NOPASSWD: /usr/sbin/nagiostats
centreon   ALL=NOPASSWD: /usr/sbin/nagios *

Außerdem muss der Schritt: „Setting up key authentication using SSH“ noch mit dem centreon Benutzer ausgeführt werden. Also:

su centreon
ssh-keygen
(alles mit Enter bestätigen (kein Kennwort!)
ssh-copy-id -i ~/.ssh/id_rsa.pub centreon@{IP_ADDRESS}

Hat man nun den Poller im Centreon angelegt, wie in der Doku hier beschrieben, kann man Testweise einen Host anlegen, der von dem neuen Poller abgefragt werden soll.
Anschließend unter Configuration -> Monitoring Engines, die Konfiguration exportieren und den neuen Poller neustarten lassen.
Wichtige Infos zum Debuggen findet man in den Logfiles von Centreon. Ein Beispiel für ein funktionierenden Poller:

vi /usr/local/centreon/log/centcore.log
2013-06-18 14:22:01 - Info: copied rotated file for instance 5
2013-06-18 14:34:54 - Start: Send config files on poller 5
2013-06-18 14:35:05 - End: Send config files on poller 5
2013-06-18 14:35:18 - Init Script : 'sudo /etc/init.d/nagios restart' On poller 101.1.39 (5)
2013-06-18 14:35:18 - Engine : Running configuration check...done.
2013-06-18 14:35:18 - Engine : Stopping nagios: .done.
2013-06-18 14:35:18 - Engine : Starting nagios: done.
2013-06-19 00:00:42 - Info: copied rotated file for instance 5
Timeout, server 10.0.199.39 not responding.^M
2013-06-20 00:01:00 - Info: copied rotated file for instance 5
Timeout, server 10.0.199.39 not responding.^M
2013-06-20 23:59:49 - Info: copied rotated file for instance 5

Sollten die neu angelegten Hosts zwar in der Centreon Konfiguration sein, aber nicht unter Monitoring auftauchen muss geprüft werden, ob der ndoutils Dienst korrekt läuft.
Dazu das Nagios-Log auf dem Poller checken:

vi /usr/local/nagios/var/nagios.log

VMware ESXi 5 mit Nagios/Centreon überwachen

VMware bietet mit seinem vSphere Client bzw. des vSphere Webclient eine schönes Tool zur Verwaltung der ESX Farm. Dort kann man sich auch die Performancewerte zu CPU, Ram, HDD, Netzwerk anschauen, Graphen erzeugen und vieles mehr…. Wer jetzt aber ein bestehendes System zum Monitoren hat, freut sich mit Sicherheit darüber, dort auch alle Systeme aufnehmen zu können.
Da seit dem ESX3 die SNMP Funktionalität bzw. alle nützlichen Attribute daraus gänzlich entfernt wurden, bleibt zum Abfragen nur die PowerCLI bzw. die Perl SDK. Wie das funktioniert beschreibe ich hier:
Als erstes die aktuellste VMware vSphere Perl SDK installieren. Momentan 5.1.0 – gibt’s bei VMware.
Entpacken:

tar xvf VMware-vSphere-Perl-SDK-5.1.0-780721.x86_64.tar.gz

Umgebungsvariablen setzen: (WICHTIG – ohne geht’s nicht!)

export http_proxy=
export ftp_proxy=

Installer ausführen:

sudo ./vmware-install.pl

Perl Module installieren:

perl -MCPAN -e shell

Anschließend für die unten aufgelisteten Module jeweils machen:

install XML::Simple
XML::Simple
Nagios::Plugin
Class::MethodMaker
URI
LWP
HTML::Parser

Das Nagios Plugin / Script herunterladen: check_vmware_api
Jetzt noch die SSL Überprüfung vom LWP Modul zu deaktivieren. Ich empfehle folgendes noch in den Kopfbereich des check_vmware_api Scriptes hinzuzufügen:

$ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0;

Alternativ kann man die Einstellung auch Global vornehmen:

sudo vim /usr/share/perl5/LWP/Protocol/https.pm

In der Datei nach der Zeile:

$ssl_opts{SSL_verify_mode} ||= 1;

suchen und diese durch folgende ersetzen:

$ssl_opts{SSL_verify_mode} ||= 0;

Ansonsten bekommt ihr eventuell folgende Fehlermeldung:

CHECK_ESX3.PL CRITICAL - Server version unavailable at 'https://MYESX:443/sdk/vimService.wsdl' at /usr/lib/perl5/5.10.0/VMware/VICommon.pm line 545.

Zum Testen kann man sich nun mal den Gesamtverbrauch an CPU Ressourcen in MHZ ausgeben lassen:

root@SERVER:/# /usr/local/nagios/libexec/check_esx3.pl -D vcenter.domain.info -u user@domain.info -p password -l cpu -s usagemhz
CHECK_ESX3.PL OK - cpu usagemhz=31792.00 MHz | cpu_usagemhz=31792.00Mhz;;

Insgesamt gibt es sehr viele Optionen, die komplette Liste gibts hier:

Howto: Aktualisierung von Centreon 2.3.9 auf 2.4.0

Seit ein paar Tagen gibt’s eine neue Centreon Version mit einem etwas überarbeitetem Design.
Es können nun eigene Widgets erstellt und hinzugefügt werden, was mit Sicherheit nett ist, wenn es mal ein paar gibt 🙂
Desweiteren natürlich einige Bug-Fixes etc….
Ich beschreibe hier wie man auf einem Ubuntu 10.10 mit der bisherigen Version 2.3.9 auf die aktuelle Version kommt.
1. Centreon herunterladen & entpacken

cd /tmp/
wget http://download.centreon.com/index.php?id=4264 -C centreon-2.4.0.tar.gz
tar xzfv centreon-2.4.0.tar.gz

2. Config Dateien lokalisieren

root@SERVER:/tmp/centreon-2.4.0# find / -name "instCent*"
/etc/centreon/instCentPlugins.conf
/etc/centreon/instCentWeb.conf
/etc/centreon/instCentStorage.conf
/etc/centreon/instCentCore.conf

3. Upgrade starten

root@SERVER:/tmp/centreon-2.4.0# ./install.sh -u /etc/centreon/

Ich muss ganz ehrlich gestehen – bei den beiden Fragen war ich mir auch nicht ganz sicher – hat bei mir allerdings funktioniert:

Where is the configuration directory for broker ?
Where is the init script for broker module daemon ?

4. Datenbankupgrade durchführen
Das Datenbankupgrade wird über die Webseite durchgeführt, dazu eure Centreon URL aufrufen und den 3 -> Steps folgende.
(Sorry diesmal keine Bilder.) Aber immer 3 x weiter klicken solltet ihr ja schaffen 😉
5. Reboot
Anschließend den Server booten um sicher zu sein, damit auch alles korrekt funktioniert 🙂

Troubleshooting NDOUtils 1.5.2

Nach der Aktualisierung von NDOUtils von 1.4b9 auf 1.5.2 wurde ich mit ein paar Fehlern zugeschmissen.
NDOUtils schreibt die Fehler ins syslog.
Erster Fehler – Tabelle defekt:

Oct  9 07:49:14 SERVER ndo2db: mysql_error: 'Table './ndo/nagios_hostchecks' is marked as crashed and last (automatic?) repair failed'
Oct  9 07:49:14 SERVER ndo2db: Error: mysql_query() failed for 'INSERT INTO nagios_hostchecks SET instance_id='1', host_object_id='1161', check_type='0', is_raw_check='0', current_check_attempt='1', max_check_attempts='5', state='0', state_type='1', start_time=FROM_UNIXTIME(1349761720), start_time_usec='784551', end_time=FROM_UNIXTIME(1349761725), end_time_usec='446306', timeout='10', early_timeout='0', execution_time='0.036930', latency='70.784000', return_code='0', output='PING OK - Packet loss = 0%, RTA = 3\.83 ms', long_output='', perfdata='rta=3\.830000ms;3000\.000000;5000\.000000;0\.000000 pl=0%;80;100;0', command_object_id='22', command_args='', command_line='' ON DUPLICATE KEY UPDATE instance_id='1', host_object_id='1161', check_type='0', is_raw_check='0', current_check_attempt='1', max_check_attempts='5', state='0', state_type='1', start_time=FROM_UNIXTIME(1349761720), start_time_usec='784551', end_time=FROM_UNIXTIME(1349761725), end_time_usec='446306', timeout='10', early_timeout='0', execution_time='0.036930', latency='70.784000', return_code='0', output='PING OK - Packet loss = 0%, RTA = 3\.83 ms', long_output='', perfdata='rta=3\.830000ms;3000\.000000;5000\.000000;0\.000000 pl=0%;80;100;0''

Lässt sich am einfachsten via phpmyadmin beheben. Einloggen – Tabellen überprüfen – und anschließend reparieren.

Zweiter Fehler: ndo2db scheint nichts mehr in die queue zu schreiben:

Oct  9 06:36:20 SERVER ndo2db: Message sent to queue.
Oct  9 06:36:20 SERVER ndo2db: Warning: queue send error, retrying...
Oct  9 06:36:21 SERVER ndo2db: Message sent to queue.
Oct  9 06:36:21 SERVER ndo2db: Warning: queue send error, retrying...
Oct  9 06:36:22 SERVER ndo2db: Message sent to queue.
Oct  9 06:36:22 SERVER ndo2db: Warning: queue send error, retrying...

Die Ursache ist wohl ein neues „Feature“ in der neuen Version 1.5.2 von ndoutils welche Nachrichten nun in eine Warteschlange setzt, wenn der Kernel sie nicht annimmt. (Korrigiert mich, wenn ich falsch liegen sollte.)
Abhilfe schafft das hoch setzen der max. Nachrichten:

vi /etc/sysctl.conf
(Einfach am Ende einfügen, falls nicht vorhanden.)
kernel.msgmax = 131072000
kernel.msgmnb = 131072000
kernel.msgmni = 65536000

Danach  habe ich noch ein Reboot gemacht.

Monitoring Appliance – Nagios, Centreon, Nagvis, Check_MK

Passend zu meinem vorangegangenem Blogpost habe ich hier nun eine fertige Appliance im .ovf Format bereit gestellt.
Als Grundlage dient ein Ubuntu 12.04 LTS wo ich die aktuellen Versionen von Nagios, Centreon, Nagvis und Check_MK vorinstalliert habe.
Damit ist das System nach der Bereitstellung direkt Einsatzbereit und man erspart sich die lange Konfigurations-/Installationszeit.
Da es meine erste Vorlage ist, besteht natürlich noch Verbesserungsbedarf wie z.B.  IP-Konfiguration oder Hostname Änderung beim ersten Login. Tipps & Hinweise nehme ich gerne entgegen 😉
 
Details:
– Ubuntu 12.04 LTS
– Nagios Core    | 3.4.1
– nagios Plugins    | 1.4.15
– Centreon     | 2.3.8
– Check_MK    | 1.2.0p1
– Nagvis        | 1.6.6
Alle notwendigen Informationen findet ihr in der Beiliegenden README.txt

How to install Nagios, Centreon, Nagvis, Check_MK @ Ubuntu 12.04 Server

Ich arbeite schon seit mehreren Jahren mit Nagios vorallem aber mit der Oberfläche: Centreon. Wer Nagios noch per Shell bedient und somit hunderte Config-Files pflegt müsste Centreon eigentlich lieben.
Eine Oberfläche von der aus alles gesteuert wird. Komfortables anlegen von Hosts, Diensten und allen notwendigen Gruppen. Mit mehreren Klicks – keine Config-Files mehr – diese werden dann durch Centreon automatisch erstellt.
Zur grafischen Anzeige benutze ich Nagvis was noch die Erweiterung check_mk benötigt. Damit lassen sich dann nette Weathermaps erstellen oder den Serverraum in einem Bild mit dem dazugehörigen Host/Service-Status darstellen.
Als Betriebssystem nutze ich ausschließlich nur Ubuntu – daher ist das Komplettpaket „FAN – Fully automated Nagios“ (CentOS) für micht nicht interessant.
Hier ein Howto zur Installation von Nagios, Centreon, Check_MK und Nagvis. In naher Zukunft werde ich auch mal ein .OVF Template erstellen….
Vorraussetzungen:
-> Ubuntu 12.04 Server installiert.
Bevor wir anfangen noch obligatorisch die Updates machen:

apt-get update
apt-get upgrade
apt-get dist-upgrade

Notwendige Abhängigkeiten installieren:

apt-get install gcc make g++ lsb-release tofrodos apache2 apache2.2-common apache2-doc apache2-mpm-prefork apache2-utils libapache2-mod-python libexpat1 ssl-cert libapache2-mod-php5 php5 php5-common php5-gd php5-mysql php5-imap phpmyadmin php5-cli apache2-suexec php-pear php-auth php5-mcrypt mcrypt libapache2-mod-suphp php5-snmp php5-ldap mysql-server rrdtool librrds-perl libconfig-inifiles-perl libcrypt-des-perl libgd-gd2-perl snmp snmpd libnet-snmp-perl libsnmp-perl libgd2-xpm libgd2-xpm-dev bsd-mailx postfix

GGf. Vmware Tools installieren (VMware Tools mounten):

mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
mount: blockorientiertes Gerät /dev/sr0 ist schreibgeschützt, wird eingehängt im Nur-Lese-Modus
tar xzfv /mnt/cdrom/VMwareTools-8.6.5-652272.tar.gz -C /tmp/
root@centreon:~# cd /tmp/vmware-tools-distrib/
./vmware-install.pl

Ich habe die VM-Tools mit Standardeinstellungen installiert. Anschließend Reboot:

shutdown -r now

GGf. Proxy im Wget eintragen:

vi /etc/wgetrc

Installation von Nagios:
Hier gibt es zwei Möglichkeiten. Entweder von Hand installieren, oder die fertigen Packete nutzen. Ich empfehle es von Hand zu installieren, da die Pakete oftmals nicht aktuell sind.
Also finger weg von: apt-get install nagios3 nagios-plugins
Nagios benutzer anlegen:

/usr/sbin/useradd -m -s /bin/bash nagios
passwd nagios

Gruppe anlegen:

/usr/sbin/groupadd nagios

Gruppe hinzufügen:

/usr/sbin/groupadd nagcmd
/usr/sbin/usermod -G nagcmd nagios
/usr/sbin/usermod -G nagcmd www-data

Nagios herunterladen:

wget http://downloads.sourceforge.net/project/nagios/nagios-3.x/nagios-3.4.1/nagios-3.4.1.tar.gz?r=http%3A%2F%2Fwww.nagios.org%2Fdownload%2Fcore%2Fthanks%2F&amp;ts=1340721679&amp;use_mirror=garr
mv nagios-3.4.1.tar.gz\?r\=http\:%2F%2Fwww.nagios.org%2Fdownload%2Fcore%2Fthanks%2F nagios-3.4.1.tar.gz
tar xzfv nagios-3.4.1.tar.gz
cd nagios/

Nagios Configurieren:

./configure --with-nagios-group=nagios --with-nagios-user=nagios --with-command-group=nagcmd

tar xzfv nagios-plugins-1.4.15.tar.gz
./configure
make
make install

Nagios starten:

/etc/init.d/nagios start

Mal die Webseite aufrufen: http://server/nagios

Wenn man nun noch Nagvis installieren will – gehts weiter.
Zuerst muss check_mk installiert werden:

wget http://mathias-kettner.de/download/check_mk-1.2.0p1.tar.gz
tar xzfv check_mk-1.2.0p1.tar.gz
cd check_mk-1.2.0p1
./setup.sh
Hier alles wieder mit Standart-Einstellungen installiert

[EXPAND check_MK Setup]
./setup.sh
Check_MK setup Version: 1.2.0p1
Welcome to Check_MK. This setup will install Check_MK into user defined
directories. If you run this script as root, installation paths below
/usr will be suggested. If you run this script as non-root user paths
in your home directory will be suggested. You may override the default
values or just hit enter to accept them.
Your answers will be saved to /home/centreon/.check_mk_setup.conf and will be
reused when you run the setup of this or a later version again. Please
delete that file if you want to delete your previous answers.
* Found running Nagios process, autodetected 18 settings.
1) Installation directories of check_mk
Executable programs
Directory where to install executable programs such as check_mk itself.
This directory should be in your search path ($PATH). Otherwise you
always have to specify the installation path when calling check_mk:
( default –> /usr/bin):
Check_MK configuration
Directory where check_mk looks for its main configuration file main.mk.
An example configuration file will be installed there if no main.mk is
present from a previous version:
( default –> /etc/check_mk):
Check_MK software
The base directory for the software installation of Check_MK. This
directory will get the subdirectories checks, modules, web, locale and
agents. Note: in previous versions it was possible to specify each of
those directories separately. This is no longer possible:
( default –> /usr/share/check_mk):
documentation
Some documentation about check_mk will be installed here. Please note,
however, that most of check_mk’s documentation is available only online at
http://mathias-kettner.de/check_mk.html:
( default –> /usr/share/doc/check_mk):
check manuals
Directory for manuals for the various checks. The manuals can be viewed
with check_mk -M <CHECKNAME>:
( default –> /usr/share/doc/check_mk/checks):
working directory of check_mk
check_mk will create caches files, automatically created checks and
other files into this directory. The setup will create several subdirectories
and makes them writable by the Nagios process:
( default –> /var/lib/check_mk):
 
2) Configuration of Linux/UNIX Agents
extensions for agents
This directory will not be created on the server. It will be hardcoded
into the Linux and UNIX agents. The agent will look for extensions in the
subdirectories plugins/ and local/ of that directory:
( default –> /usr/lib/check_mk_agent):
configuration dir for agents
This directory will not be created on the server. It will be hardcoded
into the Linux and UNIX agents. The agent will look for its configuration
files here (currently only the logwatch extension needs a configuration file):
( default –> /etc/check_mk):
 
3) Integration with Nagios
Name of Nagios user
The working directory for check_mk contains several subdirectories
that need to be writable by the Nagios user (which is running check_mk
in check mode). Please specify the user that should own those
directories:
( autodetected –> nagios):
User of Apache process
Check_MK WATO (Web Administration Tool) needs a sudo configuration,
such that Apache can run certain commands as root. If you specify
the correct user of the apache process here, then we can create a valid
sudo configuration for you later::
( autodetected –> www-data):
Common group of Nagios+Apache
Check_mk creates files and directories while running as nagios.
Some of those need to be writable by the user that is running the webserver.
Therefore a group is needed in which both Nagios and the webserver are
members (every valid Nagios installation uses such a group to allow
the web server access to Nagios‘ command pipe)::
( autodetected –> nagcmd):
Nagios binary
The complete path to the Nagios executable. This is needed by the
option -R/–restart in order to do a configuration check.:
( autodetected –> /usr/local/nagios/bin/nagios):
Nagios main configuration file
Path to the main configuration file of Nagios. That file is always
named ’nagios.cfg‘. The default path when compiling Nagios yourself
is /usr/local/nagios/etc/nagios.cfg. The path to this file is needed
for the check_mk option -R/–restart:
( autodetected –> /usr/local/nagios/etc/nagios.cfg):
Nagios object directory
Nagios‘ object definitions for hosts, services and contacts are
usually stored in various files with the extension .cfg. These files
are located in a directory that is configured in nagios.cfg with the
directive ‚cfg_dir‘. Please specify the path to that directory
(If the autodetection can find your configuration
file but does not find at least one cfg_dir directive, then it will
add one to your configuration file for your conveniance):
( autodetected –> /usr/local/nagios/etc/check_mk.d):
Nagios startskript
The complete path to the Nagios startskript is used by the option
-R/–restart to restart Nagios.:
( autodetected –> /etc/init.d/nagios):
Nagios command pipe
Complete path to the Nagios command pipe. check_mk needs write access
to this pipe in order to operate:
( autodetected –> /usr/local/nagios/var/rw/nagios.cmd):
Check results directory
Complete path to the directory where Nagios stores its check results.
Using that directory instead of the command pipe is faster.:
( default –> /usr/local/nagios/var/spool/checkresults):
Nagios status file
The web pages of check_mk need to read the file ’status.dat‘, which is
regularily created by Nagios. The path to that status file is usually
configured in nagios.cfg with the parameter ’status_file‘. If
that parameter is missing, a compiled-in default value is used. On
FHS-conforming installations, that file usually is in /var/lib/nagios
or /var/log/nagios. If you’ve compiled Nagios yourself, that file
might be found below /usr/local/nagios:
( autodetected –> /usr/local/nagios/var/status.log):
Path to check_icmp
check_mk ships a Nagios configuration file with several host and
service templates. Some host templates need check_icmp as host check.
That check plugin is contained in the standard Nagios plugins.
Please specify the complete path (dir + filename) of check_icmp:
( autodetected –> /usr/local/nagios/libexec/check_icmp):
 
4) Integration with Apache
URL Prefix for Web addons
Usually the Multisite GUI is available at /check_mk/ and PNP4Nagios
is located at /pnp4nagios/. In some cases you might want to define some
prefix in order to be able to run more instances of Nagios on one host.
If you say /test/ here, for example, then Multisite will be located
at /test/check_mk/. Please do not forget the trailing slash.:
( default –> /):
Apache config dir
Check_mk ships several web pages implemented in Python with Apache
mod_python. That module needs an apache configuration section which
will be installed by this setup. Please specify the path to a directory
where Apache reads in configuration files.:
( autodetected –> /etc/apache2/conf.d):
HTTP authentication file
Check_mk’s web pages should be secured from unauthorized access via
HTTP authenticaion – just as Nagios. The configuration file for Apache
that will be installed contains a valid configuration for HTTP basic
auth. The most conveniant way for you is to use the same user file as
for Nagios. Please enter your htpasswd file to use here:
( autodetected –> /usr/local/nagios/etc/htpasswd.users):
HTTP AuthName
Check_mk’s Apache configuration file will need an AuthName. That
string will be displayed to the user when asking for the password.
You should use the same AuthName as for Nagios. Otherwise the user will
have to log in twice:
( autodetected –> Nagios Access):
 
5) Integration with PNP4Nagios 0.6
PNP4Nagios templates
Check_MK ships templates for PNP4Nagios for most of its checks.
Those templates make the history graphs look nice. PNP4Nagios
expects such templates in the directory pnp/templates in your
document root for static web pages:
( default –> /usr/share/check_mk/pnp-templates):
 
6) Check_MK Livestatus Module
compile livestatus module
This version of Check_mk ships a completely new and experimental
Nagios event broker module that provides direct access to Nagios
internal data structures. This module is called the Check_MK Livestatus
Module. It aims to supersede status.dat and also NDO. Currenty it
is completely experimental and might even crash your Nagios process.
Nevertheless – The Livestatus Module does not only allow extremely
fast access to the status of your services and hosts, it does also
provide live data (which status.dat does not). Also – unlike NDO –
Livestatus does not cost you even measurable CPU performance, does
not need any disk space and also needs no configuration.
Please answer ‚yes‘, if you want to compile and integrate the
Livestatus module into your Nagios. You need ‚make‘ and the GNU
C++ compiler installed in order to do this:
( default –> yes):
check_mk’s binary modules
Directory for architecture dependent binary libraries and plugins
of check_mk:
( default –> /usr/lib/check_mk):
Unix socket for Livestatus
The Livestatus Module provides Nagios status data via a unix
socket. This is similar to the Nagios command pipe, but allows
bidirectional communication. Please enter the path to that pipe.
It is recommended to put it into the same directory as Nagios‘
command pipe:
( default –> /usr/local/nagios/var/rw/live):
Backends for other systems
Directory where to put backends and configuration examples for
other systems. Currently this is only Nagvis, but other might follow
later.:
( default –> /usr/share/check_mk/livestatus):

You can access the new Multisite GUI at http://localhost/check_mk/[/EXPAND]
Apache & Nagios neustarten:

service apache2 restart
service nagios3 restart

Prüfen ob Check_MK richtig funktioniert:

http://centreon.domain.info/check_mk/

Ich hatte hier schon öfters den Fehler das der Socket nicht funktioniert
Abhilfe hat folgendes gebracht:

/var/lib/nagios/
chmod 777 rw/ -R
vi /etc/group
Der nagios Gruppe noch www-data hinzufügen.

Um das Linux System zu Überwachen benötigt es einen Dienst der auf dem Remote-System installiert werden muss. (Wie bei Windows der NSClient)
1. NRPE Installieren (Remote System – zu Überwachende)

apt-get install nagios-plugins nagios-nrpe-server

2. Anschließend die Konfigdatei bearbeiten, und die IP-Adresse des Nagios-Servers eintragen.

command[check_freespace]=/usr/lib/nagios/plugins# ./check_disk -w 10% -c 5% -p /dev/sda1
command[check_http]=/usr/lib/nagios/plugins# ./check_http -w 5 -c 10 -H intranet.domain.info
command[check_http]=/usr/lib/nagios/plugins# ./check_tcp -H localhost -p 80

3. Anschließend den nrpe-daemon starten:

/etc/init.d/nagios-nrpe-server start

 
Nun sollte es möglich sein vom Nagios-Server aus den Server zu erreichen und die Commands abzufragen.

/usr/lib/nagios/plugins/check_nrpe -H 11.1.11.1
NRPE v2.8.1

Bsps. für die Abfrage eines vorher festgelegten Commands:

/usr/lib/nagios/plugins/check_nrpe -H 11.1.11.1 -c check_mysqldb
