Mit Begeisterung habe ich den Artikel VM Performance Summary with vRO von Ivaylo Ivanov verschlungen. Mein erster Gedanke war sofort den Workflow auch als vRealize Automation VM Performance Summary (XaaS) umzusetzen.
Dafür war gar nicht viel Anpassung notwendig, Ivaylo Ivanov hat sehr gut Arbeit bei dem vRealize Orchestrator Workflow geleistet.
Folgendes musste angepasst werden:
- Ausgabe nicht mehr über User Interaktion sondern als Mail
- Angepasstes Error Handling
Ausgabe des vRealize Automation VM Performance Summary:
Hinweiß:
Das Design der Mail ist nicht das endgültige, das überlasse ich lieber Leuten mit echtem HTML Know-How…
vRealize Automation VM Performance Summary Anforderung
Ich habe mich hierbei für eine Action entschieden. So hat der Enduser ohne zusätzliche Auswahl einen schnellen Zugriff und das Thema Sicherheit (nur Zugriff aus seine Elemente) ist auch kein Thema.
Wie auch in dem originalen Workflow, muss der Zeitraum der Statistiken gewählt werden. Die Eingabe der Email Adresse ist für diesen Ansatz neu.
vRealize Automation VM Performance Summary Workflow
Der Hauptteil des vRealize Automation VM Performance Summary steckt in dem Script Task „Get and calculate„. Diesen habe ich nur um die Generierung des Email Body erweitert (siehe Markierung am Ende).
