Host Availability Widget doesn't show all hosts

[avbxl]

I've been Using Zabbix for a while now, and noticed a discrepancy between the Host Availability widget and my number of hosts:

The total in the widget shows as 197, but the Zabbix Server Information widget shows something else:

All host groups are selected to be in the Host Availability widget, and there are no hosts that don't belong to a host group (as far as I know).
What could be causing this difference?

"host availability" widget allows you to check, what type of interfaces you consider - Agent, JMX, SNMP... If you only select agents and you have a bunch of snmp only devices, numbers will not match..

I selected all of them, including hosts in maintenance mode...

No you did not... otherwise you would have also lines for other IF types there... You selected all hosts, but not all IF types..



I know for sure, that I have bunch of hosts, which have no Interfaces.. used for calculated items etc..

I did select all IF types, I did also do show only totals, as I don't care about the different ones, I just want to see the total...?
Still this total does not match...
