Data overwiev widget doesn´t show all records

[TRNX]

Hello.

I had a dashboard with all my hosts and their agent version (via overview widget), so I could check which host needs update.
A few days back I upgraded Zabbix Server to 5.0.0 (from 4.4.4) and after upgrade my dashboard with hosts agent version doesn´t show all host (I see only 50). At the end of the screen it writes: "Not all results are displayed. Please provide more specific search criteria."

Is there any solution to resolve it and see all host and their agent versions on one page (dashboard)?

Thank you.

This is a major problem for me as well. It does not make sense since data overview is not slow due to a long list of hosts but rather a large amount of data shown in columns. There should be a setting for max lines of hosts to show with a global threshold for max.

I found setting "rows per page" in User settings tab, but it works for latest data or items. In overview widget it is still only 50 rows.

I found the solution:

/usr/share/zabbix/include/defines.inc.php

was define('ZBX_MAX_TABLE_COLUMNS', 50);

now define('ZBX_MAX_TABLE_COLUMNS', 500);

file /usr/share/zabbix/include/defines.inc.php
change define('ZBX_MAX_TABLE_COLUMNS', 50);

Thank you very much! Solved.

Can anyone confirm if this definition still exists in 5.2? I can't find it in my defines.inc.php file, adding it manually doesn't work.

Edit: I changed the option in Administration>General>GUI>Max number of columns and rows in overview tables to 500 and now it's good. I guess 5.2 doesn't use the definition anymore?

When updating, I highly recommend reading about the changes. To avoid poking around like a blind dog.

NEW CONFIGURATION PARAMETERS


Several parameters, that previously could only be modified through editing defines.inc.php file, can now be configured directly via the frontend. This makes Zabbix frontend configuration more flexible and ensures that custom changes will be preserved after an upgrade.

Administration → General frontend section has been modified to accommodate more parameters:

• General → GUI page now
  • includes Working hours field (used to be on a separate page);
  • contains new parameters: Max number of columns and rows in overview tables, Show technical errors, Max history display period, Default period (for graphs and dashboards), Max period (for graphs and dashboards).
• Working time page has been removed.
• Trigger severities page is moved to Trigger displaying options.
• Other page now includes three additional parameter groups:
  • Authorization, which allows to set number of failed login attempts and period of blocking login page after exceeding this limit;
  • Security, which allows to set URI scheme validation rules, X-Frame-Options HTTP header, and custom iframe sandboxing restrictions;
  • Communication with Zabbix server, which allows to customise timeout limits.
