Add a host to a network map via Zabbix API

[sire]

Hi

I'm trying to add a host to a network map via Zabbix API. The request is performed without error, but the host doesn't appear on the map, neither does Zabbix database table sysmaps_elements change.

JSON query:

{
   "params" : {
      "selements" : [
         {
            "iconid_off" : "11",
            "iconid_unknown" : "0",
            "label_location" : "0",
            "x" : 400,
            "elementid" : "10101",
            "sysmapid" : "7",
            "iconid_on" : "0",
            "y" : 300,
            "iconid_disabled" : "0",
            "url" : "",
            "label" : "Маршрутизатор\n{IPADDRESS}",
            "elementtype" : "0",
            "iconid_maintenance" : "0"
         }
      ],
      "sysmapid" : "7"
   },
   "auth" : "4e7f3c8ff1716f84f7d3e8eef536853f",
   "jsonrpc" : "2.0",
   "method" : "map.update",
   "id" : 7
}

JSON result:

{
   "sysmapids" : [
      "7"
   ]
}

What am I doing wrong? Is the ability to modify map objects implemented in the API, or is there another way of doing this?

Zabbix version is 1.8.5rc1.x-18700.

sire, what tool are you using to send the request? Is the JSON you've posted the same as being submitted to server?

There were issues, when some tools truncated the squqare brackets and, because of that, element was not added.

Konstantin II, I am using JSON::RPC::Client perl module http://www.cpan.org/modules/by-modul...PC-0.96.tar.gz

Is the JSON you've posted the same as being submitted to server?

Yes, it is the same.

There were issues, when some tools truncated the squqare brackets and, because of that, element was not added.

I guess it's another issue, because the brackets are in place, if my understanding of https://support.zabbix.com/browse/ZBX-3685 is correct.

Konstantin II, please note, that I'm using map.update, not map.create method. And if you look at the implementation of the former one, you will notice, that it doesn't deal with selements at all.

just a quick note that it was my pre-processing, not the tool (zabcon) which nuked the square brackets

sire, you are right, sorry. I've tried a request with the same data you have, and it appears, that zabbix 1.8 has limited possibillities of interacting with maps over API. For example, you can update only map properties, but not elements - that is why your element is not being created.

API will have full map support in 2.0. Sorry for the confusion.

Using Perl module https://github.com/mikeda/ZabbixAPI I've create a numer of hosts, which now should land on a series of maps.
After a

 $za->map_create(
                [
                        {
                        name    => 'mapname',
                        width   => 800,
                        height  => 600,
                        label_type => 0,
                        }
                ]
        );

I run an update to add a host:
$sysmapid is provided with a map_get()
$hostid points to an existing host, $x and $y position on the map.

$za->map_update (
                {
                 sysmapid => $sysmapid,
                 selements =>[
                                 {
                                 sysmapid => $sysmapid,
                                 iconid_on => 128,
                                 iconid_off => 128,
                                 iconid_maintenance => 128,
                                 iconid_disabled => 128,
                                 x => $x,
                                 y => $y,
                                 elementid => $hostid,
                                 elementtype => 0,
                                 label => '{HOST.NAME}'
                                },
                         ] # selements []
                 } # map_update{}
                ); # map_update()

Works fast and as expected: I have a map with 1 host element. Problem is when I add more hosts/selements: it seems to overwrite the map data of the previous host/selement.

The [] brackets in selements are positional, how can I add a new host/selement after the last so I don't overwrite the data?

My network maps have different amount of hosts, so create the maps with the variable number of hosts/selements would be troublesome to do.

To manipulate elements on a map in 1.8 you can use the map.addElements, map.updateElements and map.deleteElements. They are not documented, so you'll need to have a look at the source code, to see how they work.

$ tar zxvf zabbix-2.0.2.tar.gz
$ cd zabbix-2.0.2/
$ grep -i addselements `find .`

Doesn't find addElements, neither in zabbix 2.1.0 download.

looks like in 2.0 it's createSelements
unfortunately manual doesn't seem to know anything about that either...

In 2.0 it's map.createSelements, map.updateSelements and map.deleteSelements.
