Hi!
I tried to update Item params with item.update method of zabbix api, all params has changed succesfully, but 'name' field hasn't updated.
Here is my json requests to zabbix:
10: json_obj: {'params': {'itemid': u'30917', 'key_': 'failcounter[parts5.time_median]', 'name': 'Failcounter: \xd0\xa1\xd1\x82\xd0\xb0\xd1\x82. \xd1\x81\xd1\x80\xd0\xb5\xd0\xb4. \xd0\xb2\xd1\x80\xd0\xb5\xd0\xbc\xd1\x8f \xd0\xbe\xd1\x82\xd0\xb2\xd0\xb5\xd1\x82\xd0\xb0 \xd0\xbf\xd1\x80\xd0\xbe\xd0\xb5\xd0\xba\xd1\x82\xd0\xb0 parts5', 'description': 'Failcounter: \xd0\xa1\xd1\x82\xd0\xb0\xd1\x82. \xd1\x81\xd1\x80\xd0\xb5\xd0\xb4. \xd0\xb2\xd1\x80\xd0\xb5\xd0\xbc\xd1\x8f \xd0\xbe\xd1\x82\xd0\xb2\xd0\xb5\xd1\x82\xd0\xb0 \xd0\xbf\xd1\x80\xd0\xbe\xd0\xb5\xd0\xba\xd1\x82\xd0\xb0 parts5', 'delay': 300, 'trends': 30, 'value_type': 0, 'templateid': u'10307', 'type': 0, 'history': 14}, 'jsonrpc': '2.0', 'method': 'item.update', 'auth': u'2dcaf3d694a7aea4c656549728c6009e', 'id': 217} 20: Sending: {"params": {"itemid": "30917", "key_": "failcounter[parts5.time_median]", "name": "Failcounter: \u0421\u0442\u0430\u0442. \u0441\u0440\u0435\u0434. \u0432\u0440\u0435\u043c\u044f \u043e\u0442\u0432\u0435\u0442\u0430 \u043f\u0440\u043e\u0435\u043a\u0442\u0430 parts5", "description": "Failcounter: \u0421\u0442\u0430\u0442. \u0441\u0440\u0435\u0434. \u0432\u0440\u0435\u043c\u044f \u043e\u0442\u0432\u0435\u0442\u0430 \u043f\u0440\u043e\u0435\u043a\u0442\u0430 parts5", "delay": 300, "trends": 30, "value_type": 0, "templateid": "10307", "type": 0, "history": 14}, "jsonrpc": "2.0", "method": "item.update", "auth": "2dcaf3d694a7aea4c656549728c6009e", "id": 217} 10: Sending headers: {'Content-Type': 'application/json-rpc', 'User-Agent': 'python/zabbix_api'} 20: Response Code: 200 10: Response Body: {u'jsonrpc': u'2.0', u'result': {u'itemids': [u'30917']}, u'id': 217}
I'm using python api for making requests. Item 'failcounter[parts5.time_median]' is templated item, and it belongs to template 'Template_App_failcounter".
