JSON API output filter

[akushner]

From zabbix API documentation:

Get methods output parameter

Output can be “shorten”, “refer”, “extend” and array of db field names.

-shorten: only ids of elements are returned. (for hosts it's hostid, for items itemid etc)
-refer: element ids are returned with element ids that were used in query.
For example request item.get(output: refer, hostids: [1,2,3])) will return items with itemids and hostids.
-extend: all db fields of element are returned (select *)
-array of db fields: listed db fields are returned


What is the correct format to pass an array of db fields? I have tried the following:

{
   "id":"1",
   "method":"item.get",
   "params":
   {
	"search":{"description":"Comp."},
	"seachWildcardsEnabled":"1",
	"output":["lastvalue","lastclock","host"]
   },
   "jsonrpc":"2.0",
   "auth":"045fe742cf405bb83281bff2567b1eef"
}

but this only returns the itemids

{
   "jsonrpc":"2.0",
   "result":[
      {"itemid":"22319"},
      {"itemid":"22318"},
      {"itemid":"22328"},
      {"itemid":"22330"},
      {"itemid":"22332"},
      {"itemid":"22334"},
      {"itemid":"22336"},
      {"itemid":"22338"},
      {"itemid":"22324"},
      {"itemid":"22326"},
      {"itemid":"22325"},
      {"itemid":"22327"},
      {"itemid":"22329"},
      {"itemid":"22331"},
      {"itemid":"22333"},
      {"itemid":"22335"},
      {"itemid":"22337"},
      {"itemid":"22339"}],
   "id":"1"
}

or is there a different way to filter the returned fields?

Not supported for items

After doing a little more digging, I found an update that states the following

from http://www.zabbix.com/documentation/...etting_started

“output”:“extend” means that you want to get all available info about each group. This, in a way, is similar to “SELECT *” in SQL. Possible options of “output” are:

“extend” - get all info;
“shorten” - get only ids of an object;
“refer” - get id of an object and also ids of related objects;
list of fields, like [“groupid”, “name”] - get only listed fields.

List of fields is only supported in Alert, DCheck, Host, DService, Screenitem, Template and Trigger get methods.
