    Problems panel doesn't work on the Dashboard

    Click image for larger version Name: image_18830.jpg Views: 5 Size: 286.2 KB ID: 422831


    Hello, I need your help.

    All "Problems" panels stopped working..

    The Zabbix version is:
    Zabbix 4.0.9. © 2001–2019.

    I tried to restart the Zabbix server and it's doesn't help....

    Where can I check to figure out what is the reason of this issue?


    For now I only did see Disk I/O is overloaded on Zabbix server.

    The hosts are over 400.

    Thank you in advance.

      I have the same problem.
      I only have a few dozen Web Scenarios on V5.2, but they do not appear in the "Problems" Dashboard Widget.

              Not yet, still trying to figure it out. I am not an "expert" in Zabbix by any means. I am hoping someone else chimes in here with some ideas.

                  I know the solution but it's too expensive and teams will not approve it.

                  1U or 2U Server machine with SSD disks 2 x CPU and 32 GB RAM minimum....

                  But you know for monitoring system a lot of companies don't invest too much in these monitoring systems......

                  One VM machine in Vmware ESXi .... and so...

                  I believe here something is wrong with the performance.
                  With Cache values and a lot of reading and write operations in DB.
                  Here in our environment DB and Zabbix server are under two different VM machines.
                  We see high CPU usage and DISK IO usage only in DB server.


                  These problems started when we connected Grafana to Zabbix Api and we added 6 hosts with SNMP V3.
                  And few modifications with discovery rules with small refresh intervals and item refresh intervals to achieve good graphics.

                  And now I am not able to stop Grafana because it's used in the production environment and people love it....

                  Grafana server is under another VM server with Windows Server 2019, Grafana just read from DB server of Zabbix...

                  I can't figure out how to handle this issue.

                  We will appreciate any help from Zabbix advanced users in the Zabbix community.

                  Thank you in advance.
