    In "Latest Data" one of three hosts disappear: limit in displaying data or bug?

    Hi, I am using Zabbix with no contract, so I cannot write a bug report and I am not sure that it is a bug.

    Situation: VMware virtual server with SUSE Linux Enterprise Server 15 SP6
    Registered TEST with Zabbix and started to monitor, worked fine.

    This week development asked to create STAGEING and PRODUCTION server.
    Being a VM I just cloned TEST -> STAGEING, started monitoring, worked fine.

    Later I cloned STAGEING -> PRODUCTION. So all three servers are essentially the same. Started monitoring, worked fine.

    I went to the page "Monitoring/Latest data" and selected the host group all three servers are in: two appear in the page with data, one not.
    If I chose all three of them servers in the host field, two appear with data, one not.

    So my question is, if this is a bug or if there is a limit on number of items/tags I can concurrently display on the Monitoring/Latest data page ...

    Thank you for shedding light on this.
    Kind regards

      You can still submit bugreports to Zabbix, if you do not have any support contract.. Contract gives you highway to solution of your current case, whatever it may be..

      Maybe you should go over the PROD config, Maybe there are some red "!"-s in item configs, which would indicate some issues...

          Also check firewalls and routing. You may have ports open in STAGING , TEST environments but not for PRODUCTION
          Test connection from zabbix server/proxy to vcenter api URL.

              Hello cyber, thank you for commenting.
              Yes, there are some red "!" signed items, a couple even pertains to Docker monitoring. I will try to solve them, of course, and thank you for the hint.
              In my humble opinion though that should not explain why a server with its data becomes hidden altogether. But one would never know for sure ...

              Thank you.

                  Hello guntis_liepins, thank you for commenting.
                  Again, as for the cyber's comment, it is not that some items are not detected or throw errors. It's that adding a third server to the Latest Data page, nothing comes up for the added server, not even the server name.
                  When I remove another server from the list, the third appears with its data ... it's not that data is not collected from that particular server.

                  Thank you.

                      Besides, cyber, you might be able to help me with this: is there a page where I can see all red "!"-s together?
                      Thank you and kind regards
