API: Get hosts linked to a template

[tuo]

Hello community,

I am currently stuck at a problem I can't seem to solve.

I need to get all hosts which are linked to a template.
I can query the template fine, I can query hosts based on other filters fine, but I can't get it to work with template or group ids.

I am using Andrew Farleys PHP class (kudos to Mr. Farley!), the JSON Request it creates looks like this:

Content-Type: application/json-rpc [1] => User-Agent: ZabbixAPI v1.0 - http://andrewfarley.com/zabbix_php_api ) [10036] => POST [10015] => {"auth":"5eea9eee2c313eb7b20fceff058f12c0","method":"host.get","id":1,"params":{"extendoutput":1,"filter":{"templateids":["10053"]}},"jsonrpc":"2.0" 

The template id is definitely correct. This is how I call it from PHP:

$hosts = ZabbixAPI::fetch_array('host','get',array('extendoutput'=>1, 'filter'=>array('templateids' => array($template[0]["templateid"])))); 

It always returns all hosts, as if I have given an empty filter. What am I doing wrong?

I also tried:

$hosts = ZabbixAPI::fetch_array('host','get',array('extendoutput'=>1, 'filter'=>array('templateids' => array("templateid" => $template[0]["templateid"])))); 

without success.

Any help is greatly appreciated!

regards

tuo

I hate to bump threads, but this problem currently sadly is a big show stopper for me, as I can't progress any further.

Has anyone ever faced (and solved) a similar problem?

best regards

Solution!

You should use "selectHosts" parameter in the method "template.get" for get all hosts linked with your template.

Hello,

would you have an example of selectHosts usage?

Hosts of a single template

Request:

{
    "jsonrpc": "2.0",
    "method": "template.get",
    "params": {
        "output": ["templateid"],
        "selectHosts": ["hostid", "name"],
        "templateids": ["10047"]
    },
    "auth": "{{token}}",
    "id": 1
}

Response:

{
  "jsonrpc": "2.0",
  "result": [
    {
      "templateid": "10047",
      "hosts": [
        {
          "hostid": "10084",
          "name": "Zabbix server"
        },
        [...]
      ]
    }
  ],
  "id": 1
}

You can specify more fields to return for each host:

   "params": {
      "selectHosts": ["hostid", "host", "name", "description", "status"],
      [...]
   }

or even tell the API to return all known fields of the host:

   "params": {
      "selectHosts": "extend"
      [...]
​   }

Hosts of all templates in the system

Request:

{
    "jsonrpc": "2.0",
    "method": "template.get",
    "params": {
        "output": ["templateid"],
        "selectHosts": ["hostid", "name"]
    },
    "auth": "{{token}}",
    "id": 1
}

Response:

{
  "jsonrpc": "2.0",
  "result": [
    {
      "templateid": "10001",
      "hosts": [
        {
          "hostid": "10084",
          "name": "Zabbix server"
        },
        [...]
      ]
    },
    {
      "templateid": "10047",
      "hosts": [
        {
          "hostid": "10084",
          "name": "Zabbix server"
        },
        [...]
      ]
    }
  ]
}
