Icinga ist eine vollständig auf Open-Source-Basis basierende, skalierbare und erweiterbare Monitoring-Lösung welche die Verfügbarkeit von definierten Ressource überprüft und über eine Benachrichtigungssystem verfügt.

Zur Einbindung von Graphite in Icinga, wird ein Modul namens

• icingaweb2-module-graphite

benötigt.

Graphite ist eine Datenbank in der linear zeit synchronisiert metrische Daten gespeichert werden, welche dann durch eine „restful API“ und über ein Web-Interface bzw. eine Web-Anwendung zur grafischen Anzeige gebracht werden können.

Graphite besteht im wesentliche aus den nachfolgend genannten drei Komponenten:

1. carbon - Ein Dienst/Daemon welcher auf einem TCP-Port lauscht um Echtzeitdaten zeit synchronisiert zu empfangen
2. graphite webapp - Eine auf dem Framework Django basierte Web-Anwendung, welche aus den zeit synchronisierten Daten, unter Einbeziehung von Cairo, Graphen in Echtzeit erstellt.
3. whisper - Eine einfache Datenbank Bibliothek, zur Speicherung von zeit synchronisierten Daten (ähnlichen dem Design von RRD)

Ab hier werden zur Ausführung nachfolgender Befehle root-Rechte benötigt. Um der Benutzer root zu werden, melden Sie sich bitte als root-Benutzer am System an, oder wechseln mit nachfolgendem Befehl zum Benutzer root:

$ su -
Password:

Als Voraussetzung für die Installation von Icinga sind folgende Komponenten erforderlich:

• Lauffähiger Datenbank-Server z.B. MariaDB
  • Siehe auch den internen Link: MariaDB CentOS 7
• Lauffähiger Web-Server z.B. Apache HTTP Server
  • Siehe auch den internen Link: Apache HTTP Server CentOS 7

Zur Installation von Graphite aus rpm-Paketen, müssen nachfolgende Repositories genutzt bzw. eingebunden werden:

• EPEL-Repository
• mailserver.guru-Repository

Nachfolgende Beschreibung bindet das Drittanbieter-Repository von EPEL ein.

• Siehe nachfolgenden internen Link: EPEL CentOS 7

Nachfolgend Beschreibung bindet das Drittanbieter-Repository mailserver.guru, welches von dem mir sehr geschätzten Michael Nausch betrieben wird und eine sichere und verlässliche Quelle für rpm-Pakete darstellt, wie unter nachfolgendem internen Link dargestellt, ein:

• Siehe nachfolgenden internen Link: mailserver.guru CentOS 7

Um carbon für Graphite, welches als Dienst/Deamon als Hintergrundprozess läuft, auch nach einem Neustart des Servers zur Verfügung zu haben, soll der Dienst/Daemon mit dem Server mit gestartet werden, was mit nachfolgendem Befehl realisiert werden kann:

# systemctl enable carbon-cache.service
ln -s '/usr/lib/systemd/system/carbon-cache.service' '/etc/systemd/system/multi-user.target.wants/carbon-cache.service'

Eine Überprüfung, ob beim Neustart des Server der carbon-cache.service-Dienst/Deamon wirklich mit gestartet wird, kann mit nachfolgendem Befehl erfolgen und sollte eine Anzeige, wie ebenfalls nachfolgend dargestellt ausgeben:

# systemctl list-unit-files --type=service | grep -e carbon-cache.service
carbon-cache.service                   enabled

bzw.

# systemctl is-enabled carbon-cache.service
enabled

Summary     : A Django web application for enterprise scalable realtime graphing
Description :
Graphite consists of a storage backend and a web-based visualization frontend.
Client applications send streams of numeric time-series data to the Graphite
backend (called carbon), where it gets stored in fixed-size database files
similar in design to RRD. The web frontend provides user interfaces
for visualizing this data in graphs as well as a simple URL-based API for
direct graph generation.

Graphite's design is focused on providing simple interfaces (both to users and
applications), real-time visualization, high-availability, and enterprise
scalability.

Summary     : Simple database library for storing time-series data
Description :
Whisper is a fixed-size database, similar in design and purpose to RRD
(round-robin-database). It provides fast, reliable storage of numeric
data over time. Whisper allows for higher resolution (seconds per point)
of recent data to degrade into lower resolutions for long-term retention
of historical data.

# available in version 0.9.10.
#
# sorted - All metrics in the cache will be counted and an ordered list of
# them will be sorted according to the number of datapoints in the cache at the
# moment of the list's creation. Metrics will then be flushed from the cache to
# disk in that order.
#
# max - The writer thread will always pop and flush the metric from cache
# that has the most datapoints. This will give a strong flush preference to
# frequently updated metrics and will also reduce random file-io. Infrequently
# updated metrics may only ever be persisted to disk at daemon shutdown if
# there are a large number of metrics which receive very frequent updates OR if
# disk i/o is very slow.
#
# naive - Metrics will be flushed from the cache to disk in an unordered
# fashion. This strategy may be desirable in situations where the storage for
# whisper files is solid state, CPU resources are very limited or deference to
# the OS's i/o scheduler is expected to compensate for the random write
# pattern.

# Only beneficial on linux filesystems that support the fallocate system call.
# It maintains the benefits of contiguous reads/writes, but with a potentially
# much faster creation speed, by allowing the kernel to handle the block
# allocation and zero-ing. Enabling this option may allow a large increase of

WICHTIG - Die Reihenfolge ist entscheidend, da der erste Treffer relevant ist!

Nachfolgende SQL-Datei kann z.B. im Verzeichnis /tmp mit dem Namen

• create_database_graphite.sql

erstellt werden, um die Neuanlage einer Datenbank mit dem Namen graphite durchzuführen:

-- CREATE DATABASE graphite;
CREATE DATABASE graphite;

Zur Ausführung der SQL-Datei kann nachfolgender Befehl genutzt werden, welcher jedoch die Kenntnis des root-Passwort für die Datenbank voraussetzt!:

# /usr/bin/mysql -u root -p < create_database_graphite.sql 
Enter password:

* Das Erscheinen keiner Fehlermeldung, bedeutet die korrekte Ausführung des Befehls!

Nachfolgende SQL-Datei kann z.B. im Verzeichnis /tmp mit dem Namen

• create_users_for_remote_access_to_database_graphite.sql

erstellt werden, um einen Benutzer für die Datenbank graphite zu erstellen und diesen mit den benötigten rechten auszustatten:

-- Use database.
USE mysql;
 
-- Create new users.
CREATE USER 'graphiteuser'@'192.168.0.110' IDENTIFIED BY 'geheim';
CREATE USER 'graphiteuser'@'server11.idmz.tachtler.net' IDENTIFIED BY 'geheim';
 
-- Grant privileges for database graphite to new users.

GRANT ALL PRIVILEGES ON graphite.* TO 'graphiteuser'@'server11.idmz.tachtler.net' IDENTIFIED BY 'geheim' WITH GRANT OPTION;
 
-- Make sure that priviliges are reloaded.
FLUSH PRIVILEGES;

Zur Ausführung der SQL-Datei kann nachfolgender Befehl genutzt werden, welcher jedoch die Kenntnis des root-Passwort für die Datenbank voraussetzt!:

# /usr/bin/mysql -u root -p < create_users_for_remote_access_to_database_graphite.sql
Enter password:

* Das Erscheinen keiner Fehlermeldung, bedeutet die korrekte Ausführung des Befehls!

HINWEIS - Die Einrichtung der Tabellen erfolgt zu einem späteren Installationsschritt!

HINWEIS - Noch bevor die Tabellen für die Datenbank eingerichtet werden können, ist die graphite-web Web-Anwendung einzurichten, da sonst die Anzeige der Daten und die Konfiguration von whisper unvollständig ist.

Um für Icinga2 ab Version 2.10.x ein dunkles-Standard-Theme zur Verfügung zu stellen, muss nachfolgende mitgelieferte Konfigurationsdatei aus dem Verzeichnis

• /usr/share/doc/graphite-web-0.9.16/graphTemplates.conf.example

nach

Nach Durchführung der vorhergehenden Konfigurationsschritte, sollte einem Neustart nichts im Wege stehen und die Apache VHOST-Konfiguration angezogen werden:

# systemctl restart httpd.service

HINWEIS - Es erfolgen keine weiteren Ausgaben, wenn der Start erfolgreich war !

HINWEIS - Die nachfolgenden Konfiguration werden nur dann erfolgreich sein, wenn vorhergehende Konfigurationen ebenfalls komplett durchgeführt wurden!

Nachfolgende Konfigurationsdirektiven sind ursprünglich unter nachfolgendem externen Link einsehbar:

• Graphite module for Icinga Web 2 - Configuration

oder in der README.md-Datei im Verzeichnis

• /usr/share/icingaweb2/modules/graphite/README.md

Zuerst muss die das Verzeichnis und die Konfigurationsdatei

• /etc/icingaweb2/modules/graphite/config.ini

neu erstellt werden, was mit nachfolgenden Befehlen durchgeführt werden kann:

Neuerstellung des Verzeichnisses:

# mkdir /etc/icingaweb2/modules/graphite

Neuanlage der Konfigurationsdatei in dem zuvor erstellten Verzeichnis:

# touch /etc/icingaweb2/modules/graphite/config.ini

Der Inhalt der Konfigurationsdatei sollte dann wie folgt aussehen:

[graphite]
metric_prefix = icinga2
base_url = https://graphite.tachtler.net/render?
legacy_mode = false
;if legacy mode is false (2.4 and newer):
service_name_template = "icinga2.$host.name$.services.$service.name$.$service.check_command$.perfdata.$metric$.value"

Bevor der Neustart von Icinga an dieser Stelle der Konfiguration durchgeführt werden soll, ist noch aktuell nachfolgendes inaktive Modul

• graphite

mit nachfolgendem Befehl zu aktivieren:

# icinga2 feature enable graphite
Enabling feature graphite. Make sure to restart Icinga 2 for these changes to take effect.

Danach kann der icinga2-Server mit nachfolgendem Befehle neu gestartet werden:

# systemctl restart icinga2

Mit nachfolgendem Befehl kann der Status des Icinga-Servers abgefragt werden:

Nachfolgende LOG-Dateien sollten Auskunft darüber geben, wie der Start und der Status des Icinga-Servers ist.

• /var/log/icinga2/icinga2.log
• /var/log/icinga2/error.log

Der Inhalt der LOG-Datei /var/log/icinga2/icinga2.log könnte demnach wie folgt aussehen:

[2015-12-05 09:20:10 +0100] information/Application: Shutting down...

Die LOG-Datei /var/log/icinga2/error.log sollte hingegen leer sein!

Nach der erfolgreichen Inbetriebnahme des Graphite-carbon-Server, des Icinga-Servers und des Icinga-Web, kann nun die Web-Anwendung aufgerufen werden und die Konfiguration und Aktivierung von Graphite durchgeführt werden.

Bevor die Konfiguration und Aktivierung von Graphite durchgeführt werden kann, ist es erforderlich sich über die Icinga-Web-Anwendung anzumelden.

Nach erfolgreicher Anmeldung an der Icinga-Web-Anwendung ist der Menüpunkt: Konfiguration | Module auszuwählen, wonach nachfolgende Ansicht zur Anzeige kommen sollte:

Durch die Auswahl des Module | graphite werden weitere Konfigurationen zum Modul graphite angezeigt, darunter auch die Status disabled aktivieren (welche noch auf disabled eingestellt ist). Durch die Auswahl des [Links] aktivieren, kann nun Graphite aktiviert werden:

Nach erfolgreicher Aktivierung, sollte sich die Anzeige wie folgt verändert haben:

Graphite ist nun aktiviert!

Zur Verbesserung der Performance, könnte der Graphite carbon-cache-Server das Schreiben seiner Daten auch in eine RAM-Disk durchführen.

Nachfolgende Schritte zeigen, wie dies eingerichtet werden kann.

Der Graphite carbon-cache-Server kann mit nachfolgendem Befehle gestoppt werden:

# systemctl stop carbon-cache

Nachdem der Graphite carbon-cache-Server gestoppt ist, sollte ein neues Verzeichnis mit nachfolgendem Befehl angelegt werden:

# mkdir -p /var/lib/carbon/whisper.persistent

HINWEIS - Das so neu entstandene Verzeichnis, stellt die dauerhafte Kopie auf der Fetsplatte dar.

Anschließend kann der Inhalt des bisherigen Verzeichnisses und des zukünftigen Mount-Points der RAM-Disk in das neue Verzeichnis verschoben werden, was mit nachfolgendem Befehl durchgeführt werden kann:

# mv /var/lib/carbon/whisper/* /var/lib/carbon/whisper.persistent/

HINWEIS - Anschließend sollte nun das bishergige Verzeichnis - leer sein!

Nachfolgende Veränderung der Konfigurationsdatei

• /etc/fstab

zeigt, welche Ergänzungen hier durchgeführt werden müssen, um eine RAM-Disk anzulegen. Die RAM-Disk soll auch nch nach einem Neustart des Servers wieder Verfügbar sein.

(Nur relevanter Ausschnitt):

...
tmpfs /var/lib/carbon/whisper 		tmpfs defaults,size=512m,mode=750,uid=394,gid=391	0 0
...

Die vorhergehende Zeile bewirkt, dass

• das Verzeichnis /var/lib/carbon/whisper als RAM-Disk „gemountet“ wird
• das „Dateisystem“ ist hier tmpfs
• es gelten die defaults und weitere Angaben wie
  • Größe der RAM-Disk, hier 512 MB
  • Die Dateirechte sollen 750 lauten
  • Der Benutzer hat die ID des Benutzers: carbon
  • Die Gruppe hat die ID der Gruppe: carbon
  • Weitere mount/sync Angaben 0 0

Abschließend kann nun, durch nachfolgenden Befehl, die RAM-Disk tatsächlich „gemounted“ werden.:

# mount -a

Nachfolgende RAM-Disk - /var/lib/carbon/whisper sollte nun zu sehen sein, was mit nachfolgendem Befehl überprüft werden kann:

# df -h | grep /var/lib/carbon/whisper
tmpfs                         512M     0  512M   0% /var/lib/carbon/whisper

Damit beim Neustart oder Herunterfahren des Servers die Daten aus der RAM-Disk nicht verloren gehen, soll beim Starten und Stoppen des Graphite carbon-cache-Servers, die RAM-Disk entsprechend beim

• Start - einlesen der Daten von der Festplatte in die RAM-Disk
• Stoppen - schreiben der Daten aus der RAM-Disk auf die Festplatte

durchgeführt werden.

Dazu kann der systemd-Dienst des Graphite carbon-cache-Server, wie folgt angepasst werden.

Zuerst sollte eine Kopie des ursprünglichen systemd-Dienstes wie folgt angefertigt werden, damit bei eventuellen Updates des Graphite carbon-cache-Server die nachfolgenden Änderungen nicht verloren gehen:

# cp -a /usr/lib/systemd/system/carbon-cache.service /etc/systemd/system/carbon-cache.service

Anschließend kann die so entstandene neue systemd-Dienst-Datei wie folgt angepasst werden:

(Komplette Konfigurationsdatei)

[Unit]
Description=Graphite Carbon Cache
After=network.target

[Service]
Type=forking
StandardOutput=syslog
StandardError=syslog
ExecStartPre=/usr/bin/rsync -ratv /var/lib/carbon/whisper.persistent/ /var/lib/carbon/whisper/
ExecStart=/usr/bin/carbon-cache --config=/etc/carbon/carbon.conf --pidfile=/var/run/carbon-cache.pid --logdir=/var/log/carbon/ start

PIDFile=/var/run/carbon-cache.pid
TimeoutStartSec=2min 30s
TimeoutStopSec=2min 30s

[Install]
WantedBy=multi-user.target

Neu sind hier die vier nachfolgenden Zeilen:

Die erste Zeile bewirkt, dass die Daten von der Festplatte in die RAM-Disk eingelesen werden, bevor der Graphite carbon-cache-Server gestartet wird.

ExecStartPre=/usr/bin/rsync -ratv /var/lib/carbon/whisper.persistent/ /var/lib/carbon/whisper/

Die zweite Zeile bewirkt, dass die Daten von der RAM-Disk auf die Festplatte geschrieben werden, nachdem der Graphite carbon-cache-Server gestoppt wurde.

ExecStopPost=/usr/bin/rsync -ratv /var/lib/carbon/whisper/ /var/lib/carbon/whisper.persistent/

Die dritte Zeile bewirkt, dass ein Möglicher Timeout beim starten des Daemon/Dienstes von standardmäßig - 1min 30s auf z.B. hier 2min 30s erhöht wird, was notwendig sein kann, wenn viele Daten via rsync zu kopieren sind!

TimeoutStartSec=2min 30s

Die vierte Zeile bewirkt, dass ein Möglicher Timeout beim beenden des Daemon/Dienstes von standardmäßig - 1min 30s auf z.B. hier 2min 30s erhöht wird, was notwendig sein kann, wenn viele Daten via rsync zu kopieren sind!

TimeoutStopSec=2min 30s

Nachfolgender Befehl, gibt die Änderungen dem systemd-Dienst bekannt: (Änderung der „Timeout“-Zeiten)

# systemctl daemon-reexec

Nachfolgender Befehl, gibt die Änderungen dem systemd-Dienst bekannt: (Änderung von „Exec-Start/Stop)

# systemctl daemon-reload

Um nicht nur beim Stoppen des Graphite carbon-cache-Server die Daten von der RAM-Disk auf die Festplatte zu schreiben, sondern dies auch in regelmäßigen Abständen durchzuführen, kann nachfolgender cron-Job angelegt werden:

(Nur relevnater Ausschnitt)

PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root

# For details see man 4 crontabs

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name  command to be executed

# Tachtler
# rsync from RAM-Disk: /var/lib/carbon/whisper/(all files) to HDD-Disk: /var/lib/carbon/whisper.persistant/(all files)  
*/30 * * * * root /usr/bin/rsync -ratv /var/lib/carbon/whisper/ /var/lib/carbon/whisper.persistent/ >/dev/null 2>&1

HINWEIS - Vorhergehender cron-job synchronisiert alle 30 Minuten die Daten aus der RAM-Disk auf die Festplatte.

Der Graphite carbon-cache-Server kann mit nachfolgendem Befehle gestartet werden:

# systemctl start carbon-cache
