UUID when importing new items

[mseemann]

when i try to set a (huge bunch of items, which i do not want to configure manually), the import does not like it:
Invalid tag "/zabbix_export/templates/template(1)/items/item(1)": the tag "uuid" is missing.
However, the docs say it is generated if missing: "Universal unique identifier, used for linking imported item to already existing ones. Used only for items on templates. Auto-generated, if not given."
If this is not working, can someone point out how to create one? randomly using 0-9a-z does not work

Hi,

The thing is that all new items/templates whatever need to have unique uuid's.

I had a similar challenge. I tried to export an existing template, add a lot of items and reimport. What I did:
Use a UUID (V4) generator like uuidgenerator.net
Copy a bulk number of UUIDs
Use text editor like Sublime to multi edit and copy
Per UUID remove the - characters to get plain 32 characters
Import the template and done

Hello,

I know this article is a year old, but it has no answer and I am here to give it.

I have generated a PHP code that changes all the UUIDs for you to upload.

Just set your .yaml as old.yaml, run the php and it will create a new.yaml.

If you want a saas version, let me know.

<?php

    //content
    $content = file_get_contents('old.yaml');
    $content = preg_replace_callback("|uuid: (.*)\n|U", function ($matches) { return "uuid: ".str_replace('-', '', generateUUIDv4())."\n"; }, $content);
    
    $fp = fopen("new.yaml", "w");
    fwrite($fp, $content);
    fclose($fp);
        
    
    function generateUUIDv4() {
        $data = random_bytes(16);

        // Set version (4) and variant (2) bits
        $data[6] = chr(ord($data[6]) & 0x0f | 0x40);
        $data[8] = chr(ord($data[8]) & 0x3f | 0x80);

        // Convert binary data to hexadecimal format
        $uuid = vsprintf('%s%s-%s-%s-%s-%s%s%s', str_split(bin2hex($data), 4));

        return $uuid;
    }


    echo $content
    

?>​

Try this:

# Define the file path
$filePath = "C:\path\to\your\file.yaml"

# Read the file content
$content = Get-Content $filePath -Raw

# Define the regex pattern to find UUIDs
$pattern = '(?<=uuid:\s)[0-9a-f]{32}'

# Function to generate a new UUID
function New-UUID {
return [guid]::NewGuid().ToString('N')
}

# Replace all found UUIDs with new ones
$newContent = [regex]::Replace($content, $pattern, { param($match) New-UUID })

# Write the modified content back to the file
$newContent | Set-Content $filePath -NoNewline

Write-Host "UUIDs successfully replaced in file $filePath"

Im use Notepad++ with plugin PythonScript and simple script for regenerate uuid

import uuid

def calculate(match):
    IdNew = str(uuid.uuid4()).replace("-", "")
    return '- uuid: ' + IdNew
    
editor.rereplace(r'- uuid: [A-Za-z0-9]+', calculate)
