Add graph items via API

[jauge]

Hi,

I need to programatically add graph items to an existing graph.

If I understand the documentation right, I need to call the graph.update method, with an array of gitems, each of which has to have one of the following parameters:
gitemid, for the existing gitems which I don't want to modify
itemid, for the new ones I want to create

The calls I'm using look like the following one:
{"jsonrpc":"2.0","id":2,"auth":"xxxx","method":"gr aph.update","params":{"graphid": "990","gitems":[{"graphid": "990","gitemid": "3075"},{"graphid": "990","itemid": "4281"}]}}

Which gives me this answer:
{"jsonrpc":"2.0","error":{"code":-32602,"message":"Invalid params.","data":"No permissions to referred object or it does not exist!"},"id":2}

Adding new items by not setting gitemid, and setting itemid works fine. However, old items get deleted.

What am I doing wrong? Is this the correct way to add new items to a graph?

Thanks!
Jordi

Hello DRVTiny.

I fixed this by modifying the /usr/share/zabbix/api/classes/CGraphGeneral.php file.

This is a patch you should apply:

// assigning with key preserves unique itemids
$itemIds[$gitem['itemid']] = $gitem['itemid'];
+ if (isset($gitem['gitemid'])){
+ $itemIds[$gitem['gitemid']] = $gitem['gitemid'];
+ } else {
+ $itemIds[$gitem['itemid']] = $gitem['itemid'];

}
}

Good luck!
