次の形式の生のjsonがあります-
"luns": [
{
"numReadBlocks": 15444876,
"numWriteBlocks": 13530714,
"blockSizeInBytes": 512,
"writeIops": 495344,
"readIops": 312702,
"serialNumber": "aaaaaaa",
"uuid": "id",
"shareState": "none",
"usedBytes": 6721716224,
"totalSizeBytes": 16106127360,
"path": "/vol/lun_23052014_025830_vol/lun_23052014_025830"
},
{
"numReadBlocks": 15444876,
"numWriteBlocks": 13530714,
"blockSizeInBytes": 512,
"writeIops": 495344,
"readIops": 312702,
"serialNumber": "aaaaaaa",
"uuid": "id",
"shareState": "none",
"usedBytes": 6721716224,
"totalSizeBytes": 16106127360,
"path": "/vol/lun_23052014_025830_vol/lun_23052014_025830"
}]
luns にはリストが含まれている場合があります。上記のjsonとフォーム出力を次のように処理したい-
"topStorageLuns": [
{
"name": "Free (in GB)",
"data": [7.79,7.79]
},
{
"name": "Used (in GB)",
"data": [7.21,7.21]
}]
出力を取得するために次のことを試しました-
val storageLuns = myRawJson
val topStorageLuns = storageLuns.map { storageLun =>
val totalLunsSizeOnStorageDevice = storageLun.luns.foldLeft(0.0) {
case (totalBytesOnDevice, lun) =>
totalBytesOnDevice + lun.usedBytes.getOrElse(0.0).toString.toLong
}
val totalAvailableLunsOnStorageDevice = storageLun.luns.foldLeft(0.0) {
case (totalBytesOnDevice, lun) =>
totalBytesOnDevice + lun.usedBytes.getOrElse(0.0).toString.toLong
}
Json.obj("name" -> storageLun.hostId, "data" -> "%.2f".format(totalLunsSizeOnStorageDevice / (1024 * 1024 * 1024)).toDouble)
}
希望の出力を得るために誰か助けてもらえますか???
