Description
Steps to reproduce:
- Start monitoring "many" hosts for issues (>50?)
- Trigger an alert on all hosts somehow
- 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.
