Zabbix-Screens mit vielen Graphen automatisch erstellen

Zabbix-Screens zu erstellen ist recht mühsam. Hier habe ich ein Script gefunden, das automatisch alle Graphen eines Hosts in einen Screen packt. Zwar ohne jede Systematik – ich find’s aber trotzdem praktisch – vor allem bei vielen Graphen (z.B. Routern mit vielen Interfaces), um sich einen Überblick zu verschaffen.

Das geht dann z.B. so:

zabbix_create_screen.py -c 2 archerc7 all_archerc7

Das Ergebnis sieht bei mir so aus:
automatisch erstellter Zabbix-Screen mit allen Graphen eines Hosts

Und noch “bunter” wird’s mit der Option -t, welche nicht die vordefinierten Graphen sondern alle “simple graphs” (also jeden Messwert) in den Screen packt 🙂

zabbix_create_screen.py -c 2 -t archerc7 all_archerc7_simple

Anhang: Das Script

Hier das hier heruntergeladene Skript mit meiner (geringfügigen) Anpassung – nämlich dass die Elemente in den Screens nach Namen sortiert werden:
