Beschreibung

check_nwc_health ist ein Plugin für Nagios, Shinken und Icinga, welches der Überwachung von Netzwerkkomponenten dient. Es ist in der Lage, Interfacestatistiken, Hardware (CPU, Speicher, Lüfter, Stromversorgungsmodule etc.), Firewall-Policies, HSRP, Loadbalancer-Pools, Prozessor- und Speichernutzung abzufragen.

Die Kommunikation mit den Endgeräten wird über SNMP abgewickelt, wobei die Versionen 1, 2c und 3 unterstützt werden.

Bisher können damit folgende Netzwerkkomponenten, Firewalls, SAN-Switches und Loadbalancer überwacht werden:

  • Cisco IOS
  • Cisco Nexus
  • Cisco ASA
  • Cisco PIX
  • F5 BIG-IP
  • CheckPoint Firewall1
  • Juniper NetScreen
  • HP Procurve
  • Nortel
  • Brocade 4100/4900
  • EMC DS 4700
  • EMC DS 24
  • Allied Telesyn. Blue Coat SG600
  • Cisco Wireless Lan Controller 5500
  • Brocade ICX6610-24-HPOE
  • Cisco UC Telefonzeugs
  • FOUNDRY-SN-AGENT-MIB
  • FRITZ!BOX 7390
  • FRITZ!DECT 200
  • Juniper IVE
  • Pulse-Gateway MAG4610
  • Cisco IronPort AsyncOS
  • Foundry
  • ….. einzelne Checks können gegen beliebige SNMP-fähige Geräte laufen

Allerdings ist nicht jeder Modus für jeden Gerätetyp verfügbar.

Detaillierte Anleitung gibt es keine, dazu fehlt mir die Zeit. Ausprobieren und Code lesen führt auch zum Ziel. (Das Argument “ich hab aber keine Zeit” lasse ich nicht gelten. “Ich kann kein Perl” auch nicht.).

Auf der Open-Source-Monitoring-Konferenz 2014 habe ich einen Vortrag über das Plugin gehalten. Hier sind die Folien dazu:.

Changelog

Die folgenden Punkte werden nach jedem git-commit des labs-Inhalts erstellt, indem die Changelog-Datei von woanders geholt und hier eingebettet wird. D.h. das Changelog bzw. der Code auf Github kann aktueller sein als die obige tar.gz-Datei. Das liegt daran, daß ich keine Zeit oder keine Lust hatte, die Datei ins CMS zu kopieren und den Download-Link zu aktualisieren. Meistens hatte ich keins von beiden. Wenn also um 00:16 eine “ich sehe, es gibt was Neues, kannst du bitte den Download-Link aktualisieren”-Mail reinkommt, dann tut’s mir leid. Ein git pull https://github.com/lausser/check_nwc_health; cd check_nwc_health; git submodule init; git submodule update; configure; make ist nicht zu viel verlangt, oder? Die Silbertablett-Variante ist, mit Verlaub, zahlenden Kunden vorbehalten.
