automatic tasks to remove hosts

[JulBz]

Hello,

I would like to know if we can use automatic tasks to remove hosts that have not been available for 7 days. And how to do it?

I found this link : https://www.zabbix.com/forum/zabbix-...gistered-hosts , I am getting the error SyntaxError: invalid token (line 33) even though I have generated and copied the API token correctly

I may be testing wrong..

Thanks

I know this is an old thread but I was getting the same error and the cause was a hidden zero-width space in my code. Once I removed it (thanks to Zabbix support for identifying this) I was able to execute the webhook. Also, not sure about Zabbix 5 or 6, but in Zabbix 7 it DOESN'T need to be a mediatype webhook. I created mine (Zabbix 7.0) as a webhook script under Alerts -> Scripts.

Here's my version of the webhook to auto remove hosts:

try {
    Zabbix.log(4, '[ Remove host webhook ] Started with params: ' + value);

    var body,
        params = JSON.parse(value),
        request = new HttpRequest(),
        response,
        result = {};
    
    request.addHeader('Content-Type: application/json-rpc');
    request.addHeader('Authorization: Bearer ' + params.token);

    body = {
        "jsonrpc": "2.0",
        "method": "host.delete",
        "params": [params.hostid],
        "id": 1
    };

    Zabbix.log(4, '[ Remove host webhook ] Data : ' + JSON.stringify(body));

    response = request.post('https://my_zabbix_url/api_jsonrpc.php', JSON.stringify(body));

    if (request.getStatus() != 200) {
        throw new Error('Response code: ' + request.getStatus());
    }

    response = JSON.parse(response);
    result = response;
    Zabbix.log(4, '[ Remove host webhook ] Result : ' + JSON.stringify(result));
    return JSON.stringify(result);
} catch (error) {
    Zabbix.log(3, '[ Remove host webhook ] Host removal failed : ' + error.message);
    throw new Error('Failed with error: ' + error.message);
}

Give it the proper parameters for token and hostid. Then set your trigger action to execute it.
