Vsphere VMWare monitoring

Hi.
I would like to monitor my VMWare infrastructure with icinga.
I found this module:
Installation - Icinga Module for vSphere®

is it possible to use postgres instead of Mysql or Mariadb?

My Icinga installation is on postgresql db not Mysql or Mariadb

Is it the right way to monitoring VMWare?

Thanks a lot

Looking at the schema stuff in the github repo, I suspect that it only supports MySQL/Maria. You might be able to request postgres support there, or submit a PR for the feature (not a developer, but I would assume you just need the schema stuff, an option to select the IDO, and support for the IDO).
