• Http Auth: configure if you use proxy authentication.
  • Basic Auth:
  • With Credentials:

Zabbiz API details

• User and Password: setup login for access to Zabbix API. Also check user's permissions in Zabbix if you can't get any groups and hosts in Grafana.
• Trends: enable if you use patch for trends support in Zabbix 2.x (ZBXNEXT-1193). This is strictly recommended for displaying long time periods (more than few days, depending of your item's updating interval in Zabbix) because few days of item history contains tons of points. Using trends can increase Grafana performance.
  • Use trends from: time after which trends will be used. Default is 7d (7 days). You can set the time in Grafana format. Valid time specificators are:
    • h - hours
    • d - days
    • M - months
• Metrics limit: maximum items number which can be returned by one request. Helps to prevent Grafana slowdown due wrong request.

Then click Add - datasource will be added and you can check connection using Test Connection button.

This feature can help to find some mistakes like invalid user name or password, wrong api url.

Note about Zabbix 2.2 or less

Zabbix API (api_jsonrpc.php) before zabbix 2.4 don't allow cross-domain requests (CORS). And you can get HTTP error 412 (Precondition Failed). To fix it add this code to api_jsonrpc.php immediately after the copyright:

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: Content-Type');
header('Access-Control-Allow-Methods: POST');
header('Access-Control-Max-Age: 1000');

if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
  return;
}

before

require_once dirname(__FILE__).'/include/func.inc.php';
require_once dirname(__FILE__).'/include/classes/core/CHttpRequest.php';

Full fix listing. For more details see zabbix issues ZBXNEXT-1377 and ZBX-8459.
