Multiple API Requests at once

[unixdude]

Hi Guys

I have a bit of a strange problem with the JSON-RPC 2.0 API - I have managed to get single requests working fine but my problem comes when making concurrent requests.

Below is an example of a multiple request I am trying to make:

[
    {
        "jsonrpc": "2.0",
        "method": "item.get",
        "params": {
            "output": "extend",
            "hostids": "10109",
            "search": {
                "key_": "proc.num[apache2,www-data]"
            }
        },
        "id": 2,
        "auth": "xxxxxxxxxxxxxxxxxx"
    },
    {
        "jsonrpc": "2.0",
        "method": "item.get",
        "params": {
            "output": "extend",
            "hostids": "10109",
            "search": {
                "key_": "vfs.fs.size[/,used]"
            }
        },
        "id": 3,
        "auth": "xxxxxxxxxxxxxxxxx"
    }
] 

However I am getting the error "JSON-rpc version is not specified" as the response.

Can anyone confirm that they can send multiple requests at once? My zabbix version is 2.4.0.

Any help much appreciated

Well after reading through the zabbix frontend source code it really doesn't appear that it can handle multiple requests, unless I missed something. Weird as it mentions in the documentation that it can, and also in this PDF from Zabconf2012: http://www.zabbix.com/img/zabconf201...I-2_Final_.pdf (search for batch requests)

Anyway, I took an alternate approach to this in-case anyone is interested. Instead of sending individual requests I just used 'filter' option in the API call, listing multiple keys. This will return an array of results. Example below:

$req = [
                'jsonrpc' => '2.0',
                'method'  => 'item.get',
                'params'  => [
                    'output'  => 'extend',
                    'hostids' => 12345,
                    'filter'  => [
                        'key_' => [
                            'vfs.fs.size[/,used]',
                            'proc.num[apache2,www-data]',
                            'mysql.ping',
                            'system.cpu.load[percpu,avg5]',
                            'vm.memory.size[available]',
                            'net.if.in[eth0]',
                            'net.if.out[eth0]'
                        ]
                    ]
                ],
                'id'      => 1
                'auth'    => 'xxxxxxxxxxxxxxxxxxxxx'
            ]; 

Hope this helps someone else with the same problem!
