It would be good to have the number of hosts in the group names and the number and the severity of issues showing:

Name of Group 1 (number of hosts in all groups down) (2 Problems)
-> Name of group 2 (number of hosts in all groups down) (1 Problem) -> Name of Group 3 (number of hosts in Group 3)

Name of Group 1 (15) (2 Problems) -> Name of group 2 (10) (1 Problem) -> Name of Group 3 (5)

The new page just stays empty. No visible errors. See attached apache error log.

Hello, It is a fantastic job, thank you so much for that solution! We've waited something like this for years. It is so comfortable way to navigate through groups, compare them to each other and find the places, which in our case are related to groups. Instead of searching them in usual Monitoring-Host interface and reading through huge list of hosts or Groups.

If it possible, it would be good to have some development around this solution. Zabbix is missing the table presentation for hosts and has the two ways for showing data for hosts:

• Latest Data
• Dashboards + Plain Text

In both cases it is hard to see and read any information about the host. For instance, we have the WiFi AP with 30 SU (subscriber units - clients). In Zabbix we can see them in the "Latest Data", it needs to be expanded one item by one and this way works only for Zabbix < 5.2. In 5.4 the "Latest Data" functionality is broken. Dashboard does not support any tables.

So, there isn't any way to see all of items and information about them in one source like a table.

It would be good to have any way of see the table (tables) for the host.

For example, in case of WiFi AP and SUs this could be a table with fields: Client(SU name) - Mgmt IP - MAC - Product - Firmware - Distance - RX power - TX Power

In case of file systems: Name - Total - Used - Free - Percentage

In case of interfaces: Name - IP Address - MAC - Status - Bits Sent - Bits received

I will attach some pictures for illustrating this, how it is represented in Zenoss for better understanding.
