Missing hosts in Top Hosts widget

[DesperateAdmin]

Hello Forum,

I have installed a fresh Zabbix 6.2.6 running on Ubuntu 20.04, installation was without any problems.
I added 10 hosts each running Windows Server 2019. All the hosts were added to the same new group. All the hosts were added by exactly the same procedure using the template "Windows by SNMP" using SNMP v2.
I do recieve data from all the hosts individually. If I look at data "Physical Memory: Memory utilization" or "CPU utilization" the data shows in the graphs and it is current.

Problem:
Not all the 10 hosts show in the Top Hosts widget. I created a Top Hosts widget that shows memory utilization. Only hosts 1-7 show. If I reconfigure the widget to only show hosts 8-10, they show. If I add one of the hosts from 1-7, for example host 1, then hosts 8-10 disappear and only host 1 is shown.
It seams that data from hosts 1-7 and data from hosts 8-10 is incompatible. I do not understand this, as all the hosts are running the same operating system and have been set up exactly the same way.

All the hosts how in a Top Hosts widget showing cpu utilization. I only have this particular problem with a Top Hosts widget showing memory utilization.

I tired removing the problematic hosts and readding them, doesn´t work.

Any help is greatly appreciated!

Thanks

Hi,

I'm new to Zabbix and have the same problem. I have about 15 Linux and 15 Windows Servers. I found that the problem with the memory top list appears when i mix Windows and Linux servers.
When i add two separate top memory widgets, one for Linux and onf for Windows servers, all is good.

Did you, by chance, ever found a solution to this problem ?

Greetings,

Serge

Same here. It worked OK for a weeks, but days ago it started to show only the 1st host.
If I select any list of hosts, it always shows the first one by alphabetical order (not by the order set)
