Is it just me or is the learning curve a lot greater with Zabbix? The error messages seem extremely vague or completely useless. The web GUI fields don't have proper validation. They moved a lot of things around in the 6.4 version and now googling a solution gives me out of date info. The template network sensors are picking up about 20 ethernet interfaces on windows VMs in HyperV and I cant select just the one that I want to monitor (I guess I have to write my own sensor for that?).

I was demo'd Zabbix by a friend who has 39k+ sensors working on less hardware than my 1000 sensors use in PRTG, and the price difference is huge... So I really want this to work for me but I spent the whole day today feeling uneasy about it.

What are your guys thoughts?
