[#ZBX-15532] Undefined offset: 488443 [jsrpc.php:208 → CScreenProblem->get() → CScreenProblem::makeData() → usort() → CScreenProblem::{closure}() in include/classes/screens/CScreenProblem.php:603]

Comment by Miks Kronkalns [ 2019 Jan 28 ]

To reproduce this bug, trigger must be constructed from at least 2 items and one of them must be generated by web scenario.

{localhost:trap1.last()}>{$TEST} and {localhost:web.test.rspcode[scen1,step1].last()}<>0

'Show latest values' must be checked. Other filters doesn't play any role.

Hi and thank you for reporting the issue!

I was able to recreate and confirm this issue with Zabbix v. 4.0.3. when replicating the scenario described by Miks. When the trigger was in a problem state, I encountered the same error as in the issue description.

The ticket will be reassigned to the development team for further investigation.

Also it is reproducible with recovery expression with items that are not in the problem expression.

Comment by Gregory Chalenko [ 2019 Feb 28 ]

Fixed in:

4.0.6rc1 r90328
4.2.0beta2 r90331

Hi, I have the same error in the latest 5.4.0.

Undefined offset: 41681 [zabbix.php:22 → require_once() → ZBase->run() → ZBase->processRequest() → CController->run() → CControllerWidgetProblemsView->doAction() → CScreenProblem::getData() in include/classes/screens/CScreenProblem.php:343]

Thank you Alfista for report. Can you please clarify does this happen when you access using account with Zabbix super admin permissions?

Comment by Peter Danko [ 2021 May 27 ]

Hi gcalenko, yes this happens when I was loged as Zabbix Super Admin.

Comment by Ivan Vanyushkin [ 2021 May 28 ]

I can confirm this issue in v5.4.0. Seems error is triggered when operational data is displayed and web scenario is used in trigger expression.

Errors:

Undefined offset: 31563 [zabbix.php:22 → require_once() → ZBase->run() → ZBase->processRequest() → 
CController->run() → CControllerWidgetProblemsView->doAction() →

CMacrosResolver->sortItemsByExpressionOrder() → uasort() →

include/classes/macros/CMacrosResolver.php:2820]

Trigger expression:

count(/Host/web.test.fail[example.com], #5, , 0) <= 2 and length(last(/Host/web.test.error[example.com])) >= 0

Trigger name:

Website example.com failed: {ITEM.VALUE2}

Operational data is not displayed in Problems widget.

I'm logged in as super admin.

Errors from different installation and different trigger expression:
