Not to argue whether the current consolidated status calculation is right or wrong, but it's the same principle as with other interfaces:

Also,

just a placeholder for simple checks

This is likely to be included in 6.4.

Which means for the lifecycle of 6.2, all hosts that rely on Zabbix agent active + any kind of simple check, will always be grey.

I'm brand new to Zabbix, so I'm not sure if this is related, but it seems similar – and confusing.

Basically with my 6.2 server and a 6.2 agent connected with purely active checks, I do see a green ZBX agent icon that persists as long as the heartbeats come in time.  Which is good.

However, if I change that host to connect through a 6.2 proxy (active connection to server with TLS/PSK), the host initially starts out with a green ZBX agent icon but then it turns grey and "unavailable" after maybe 5 mins or so.

However the active checks are still happening, data is coming in, and I can see the host agent logging heartbeats being sent every minute.  Also if I look in the "Latest Data" for the host I even see "Active Agent Availability" is 1 which is available ?

Am I wrong to assume that active heartbeats should pass through the proxy?  or does the proxy act as another "interface" of sorts, causing the status to go grey like this issue?

I don't if it's related, but I have other way around. The interface is green, but 'Active checks' is 'Uknown' which leads to a gray ZBX icon. Zabbix version is 6.2.6

I think the Active cheks should have another icon, is somethign generic, not specific for an interface, and may be more than one icon to show which kind of active checks are running

Still the case in 7.x version

Maybe not so difficult, might be just add a condition with types in function getEnabledItemsCountByInterfaceIds :

Please zabbix.dev , can you lookup that for 7.4 ?
