Zabbix maps max label size

[Sepsisko]

Hello Zabbix community,

i have a quick question about the max label size in maps. I updated our Zabbix server to the new 3.4 version and now our max label size is default again. I wanted to change the size of the labels in the php files again, but I cannot find the line nor the file where to change this.

Can someone tell me which file I have to edit for this?

I would really like to find this out as well. I've been looking all over the forums and the zabbix feature requests to no avail. There's been plenty of talk about this over the years and even some patches that people have created to change some of the inc.php files. However, those were all written for a version of Zabbix that existed about six years ago at this point. Any instructions that I follow don't lead anywhere.

There's got to be a somewhat simple change we can make somewhere to increase the label size on maps, right?

I appreciate any help!

/usr/share/zabbix/js/vector/class.svg.map.js

There are various 'font-size' set in the file, edit, and refresh browser.

In version 4.0.1 you need to edit line 929 of /usr/share/zabbix/js/vector/class.svg.map.js

       this.element.add('textarea', {
                        x: options.center.x,
                        y: options.center.y,
                        fill: '#' + this.map.options.theme.textcolor,
                        'font-size': '10px',
                        'stroke-width': 0,
                        anchor: {
                                horizontal: 'center',
                                vertical: 'middle'
                        },
                        background: {
                        }
                }, options.label
        );

Well, i had a problem like that

Solved by change the 20 to 100 in line 1426 and 1427 on file '/usr/share/zabbix/include/items.inc.php'

That works great.
Nowadays it is line 1453 and 1454.

if ($trim && mb_strlen($value) > 20) {
    $value = mb_substr($value, 0, 20).'...';
}

I just switched the value from 20 to 38 so I could fit an IPv6 address.
