Describe the bug
In my ICINGA environment, in ICINGAWEB2 the rendering of the webpage is facing an error:
icingaweb2[5337]: Could not invoke custom navigation item renderer. ErrorException in /usr/share/icingaweb2/modules/icingadb/library/Icingadb/Web/Navigation/Renderer/TotalProblemsBadge.php:55 with message: A non well formed numeric value encountered
This problem is observed when my ICINGAWEB2 Problems exceed 1000 it gets converted to 1K. This conversion takes place in a function in file “ProblemsBadge.php”.
File location on my system: /usr/share/icingaweb2/modules/icingadb/library/Icingadb/Web/Navigation/Renderer/ProblemsBadge.php
protected function round($count)
{
if ($count > 1000000) {
$count = round($count, -6) / 1000000 . 'M';
} elseif ($count > 1000) {
$count = round($count, -3) / 1000 . 'k';
}
return $count;
}
But other functions do not handle Non-Numeric Values, when round($count) is called.
