我使用API /查询下采样来查询数据，但我得到的结果是不同的。我无法解释原因。
我的第一个问题：
{
"start": 1498838400,
"end": 1501516800,
"timezone": "Asia/Shanghai",
"useCalendar": true,
"delete": false,
"queries": [
{
"aggregator": "sum",
"metric": "meter.energy.active.forward.z",
"downsample": "24h-first",
"rate": false,
"filters": [
{
"type": "literal_or",
"tagk": "deviceId",
"filter": "127",
"groupBy": true
}
]
}
]
}
结果：
[{
"metric": "meter.energy.active.forward.z",
"tags": {
"deviceTypeId": "1",
"deviceNo": "340340001750",
"deviceId": "127",
"gatewayId": "72"
},
"aggregateTags": [],
"dps": {
"1498924800": 0.029999999329447746,
"1499097600": 349577.59375,
"1499184000": 410578.90625,
"1499270400": 515834.09375,
"1499356800": 616553.6875,
"1499443200": 722792.5,
"1499529600": 800983.75...}}]
对于第二个请求，我只将24h-first更改为24h-first-nan，第二个请求结果为：
[{
"metric": "meter.energy.active.forward.z",
"tags": {
"deviceTypeId": "1",
"deviceNo": "340340001750",
"deviceId": "127",
"gatewayId": "72"
},
"aggregateTags": [],
"dps": {}
}]
我希望结果是：
[{
"metric": "meter.energy.active.forward.z",
"tags": {
"deviceTypeId": "1",
"deviceNo": "340340001750",
"deviceId": "127",
"gatewayId": "72"
},
"aggregateTags": [],
"dps": {
"1498924800": 0.029999999329447746,
"1499011200": NaN,
"1499097600": 349577.59375,
"1499184000": 410578.90625,
"1499270400": 515834.09375,
"1499356800": 616553.6875,
"1499443200": 722792.5,
"1499529600": 800983.75...}}]
我也删除了“useCalendar”，但时间不是我想要的。
你看到我的问题了吗？你能帮我吗？谢谢！
