    Description

      Steps to reproduce:

      1. Start monitoring "many" hosts for issues (>50?)
      2. Trigger an alert on all hosts somehow
      3. Navigate to overview page, clear all filters.

      Result:
      Only some triggered alerts are seen.

      See screenshots with full problem list, overview missing triggers and overview with filter restricting number of hosts and showing more triggers.
      Expected:
      Expect to see the alerts for all hosts

       

      Further Information

      Adding > 50 hosts to the filtered hostgroup starts to remove a host from the overview page.

      Editing file /usr/share/zabbix/include/defines.inc.php
       
      // Applied to tables with variable count of columns. Columns above this limit will be truncated.
      define('ZBX_MAX_TABLE_COLUMNS', 50);
      Increasing that number to > host count seems to bypass the problem.
