Zabbix list is not displayed

[Diwahars]

Hi,

I have configured zabbix data source in grafana, but i couldn't see the hostgroup, host and item in the drop down list.

[nucleusv]

Have you specified user and password in json config? Press F12 (Developer Tools) to analyze problem.

[Diwahars]

yea i have specified user name n pwd in json config file.

[alexanderzobnin]

Please, show screenshot of datasource configuration menu

[alexanderzobnin]

Are there any errors in the browser's console? (F12 for development tools and then console tab)

[Diwahars]

Please find the screenshot of datasource config and the console tab (F12 )

[alexanderzobnin]

Does your web server require authorization?

[Diwahars]

no... i use the same URL and username n pwd to get the zabbix data using api...

[alexanderzobnin]

Look like your web server (zabbix.isus.emc.com) don't allow cross-domain requests from localhost:3000

[alexanderzobnin]

What web server are you using?

[nucleusv]

Alex, no problem in zabbix api page. Diwahars, what version of zabbix do you have?

[Diwahars]

Zabbix 2.2

Look at api_jsonrpc.php

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

/* THIS STRING ALLOWS OPTIONS TEST QUERY - ADD THIS LINE */
if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
return;
}

[alexanderzobnin]

@nucleusv zabbix api blocks cross-origin resource sharing (cross-domain requests)?

[nucleusv]

Yes, in old version. In 2.4 it seems OK, download zabbix sources, and check this, if in old versions no such line
if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
return;
}

I think it should be added to install instructions.

[Diwahars]

i have a test server with zabbix2.4.. i tried using that to... but still i get error..

[alexanderzobnin]

Can you test http instead https? May be problem in grafana.

[Diwahars]

it works with http for zabbix2.4, but still same prob exists for zabbix 2.2...

[nucleusv]

Show screenshot with zabbix 2.2 where grafana performs OPTIONS request OR request with errors, have you changed api_jsonrpc.php page ?

[nucleusv]

Have you added headers output

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

?

[Diwahars]

I have not yet changed api_jsonrpc page..., but changed https to http.. It
worked for zabbix2.4... Likewise I tried for zabbix 2.2... It didn't
work... Will check by changing the api page...

There is no other way to rectify this error... Rather than changing the api
page??

Yes, it is problem in this page

https://support.zabbix.com/browse/ZBXNEXT-1377

[Diwahars]

ok...

so i should add these headers is it?
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: Content-Type');
header('Access-Control-Allow-Methods: POST');
header('Access-Control-Max-Age: 1000');

[alexanderzobnin]

@nucleusv Is this error in zabbix 2.2 only or all version less than 2.4?

[nucleusv]

less than 2.4

[alexanderzobnin]

Ok, I'll describe this in docs.

[Diwahars]

@nucleusv should i add these headers is it?
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: Content-Type');
header('Access-Control-Allow-Methods: POST');
header('Access-Control-Max-Age: 1000');

or this one
/* THIS STRING ALLOWS OPTIONS TEST QUERY - ADD THIS LINE */
if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
return;
}
?

[nucleusv]

headers and OPTIONS check, replace if there some of these headers

[alexanderzobnin]

Added fix instructions.
