Zabbix 2.0 - Updating Host IP with API

[tom.maddox]

Hi guys,

I've just upgraded from zabbix 1.8 to 2.0 and expectedly, i've got to make some tweaks to my php API scaling scripts.

in particular, I use this code to compare an AWS instance's IP and then update the zabbix host if necessary:

if ( !strcmp($current_instances[$ai]->nameTag,$current_hosts[$zi]['host']) ) {
    //AWS host already exists in Zabbix.
    if (strcmp($current_instances[$ai]->privateIpAddress,$current_hosts[$zi]['interfaces']["$interfaceID"]['ip'])) {
        //IP needs to be updated
        $updated_interface = array('interfaceid'=>$current_hosts[$zi]['interfaces']["$interfaceID"]['interfaceid'],'ip'=>$current_instances[$ai]->privateIpAddress->to_string());
        print_r($updated_interface);
        print_r($current_hosts[$zi]['interfaces']["$interfaceID"]);
        echo "    -/+ ".$current_hosts[$zi]['host']."   IP Update:";
        if ($this->update_host($current_hosts[$zi]['hostid'],'interfaces',$updated_interface)) {
            echo " SUCCESS\n";
            $changes_made=true;
        } else {
            $errormsg = ZABBIXAPI::getLastError();
            echo " ERROR: ".$errormsg['data']."\n";
        }
   }
   $found=true;
   $safe_zabbix_hosts[]=$zi;
   break;
}

The result coming back is:

Array
(
    [interfaceid] => 36160
    [ip] => 10.32.7.186
)
Array
(
    [interfaceid] => 36160
    [hostid] => 12061
    [main] => 1
    [type] => 1
    [useip] => 1
    [ip] => 10.32.7.187
    [dns] => **************
    [port] => 10050
)
    -/+ HOSTNAME   IP Update: ERROR: Host cannot have more than one default interface of the same type.

For some reason, even thought the interfaceid's are the same, it's trying to create a new interface rather than updating the existing one.

Unfortunately there's no example of updating an interface in the API reference, so, after trying a few different things (including sending all of the fields, not just id and ip) i'm not sure how to proceed.

Any help would be really appreciated.

Thanks,
T

Worked it out.
The update function call should have been:

$this->update_host($current_hosts[$zi]['hostid'],'interfaces',[B]array($updated_interface)[/B])

rather than:

$this->update_host($current_hosts[$zi]['hostid'],'interfaces',$updated_interface)

As the API expects an array of interfaces.

This is my function update_host just for reference:

function update_host($hostid,$parameter,$value) {
   return ZabbixAPI::fetch('host','update',array('hostid'=>$hostid,$parameter=>$value));
}

Thank you for reporting the answer ...
could you add a feature request in the tracker so the API document get an update ?
