我尝试使用itemid从zabbix获取数据，当我获得CPU值时，它们会正常，但是当交换（例如）时，什么都没有，为什么？
curl -i -X POST -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","method":"history.get","params":{"itemids":[23311],"history":4,"output":"extend","time_from":"1413150714","time_till":"1413150774"},"auth":"1b7c445f0d3034082329e71e795f0604","id":1}' http://192.168.55.128/zabbix/api_jsonrpc.php

你能发布命令输出（curl -v = more verbose / talkative output）：
curl -v -i -X POST -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","method":"history.get","params":{"itemids":[23311],"history":4,"output":"extend","time_from":"1413150714","time_till":"1413150774"},"auth":"1b7c445f0d3034082329e71e795f0604","id":1}' http://192.168.55.128/zabbix/api_jsonrpc.php
