powerbi - 导入 PowerBI 的 Application Insights Data Limited

Question

我正在尝试将数据从 Azure Application Insights 导入 PowerBI。问题是，不管 timespan我设置，我似乎只提取了大约一周的数据。下面是 M 查询的样子:

let AnalyticsQuery =
let Source = Json.Document(Web.Contents("https://api.applicationinsights.io/v1/apps/<uuid>/query", 
[Query=[#"query"="customEvents
| project customDimensions
",#"x-ms-app"="AAPBI",#"timespan"="P30D"],Timeout=#duration(0,0,60,0)])),
TypeMap = #table(
{ "AnalyticsTypes", "Type" }, 
{ 
{ "string",   Text.Type },
{ "int",      Int32.Type },
{ "long",     Int64.Type },
{ "real",     Double.Type },
{ "timespan", Duration.Type },
{ "datetime", DateTimeZone.Type },
{ "bool",     Logical.Type },
{ "guid",     Text.Type },
{ "dynamic",  Text.Type }
}),
DataTable = Source[tables]{0},
Columns = Table.FromRecords(DataTable[columns]),
ColumnsWithType = Table.Join(Columns, {"type"}, TypeMap , {"AnalyticsTypes"}),
Rows = Table.FromRows(DataTable[rows], Columns[name]), 
Table = Table.TransformColumnTypes(Rows, Table.ToList(ColumnsWithType, (c) => { c{0}, c{3}}))
in
Table
in
    AnalyticsQuery

我认为这是一个大小问题，但我已经将其缩小到一列(尽管很宽)，但它仍然没有返回更多数据。

将返回的数据集缩小到两列已将数据集增加到包括几周而不是不到一周，但我仍在寻找更大的数据集。这是最新的查询:

let AnalyticsQuery =
let Source = Json.Document(Web.Contents("https://api.applicationinsights.io/v1/apps/<uuid>/query", 
[Query=[#"query"="customEvents
| extend d=parse_json(customDimensions)
| project timestamp, d[""Properties""]
| order by timestamp desc
| where timestamp <= now() and d_Properties <> """"
",#"x-ms-app"="AAPBI"],Timeout=#duration(0,0,4,0)])),
TypeMap = #table(
{ "AnalyticsTypes", "Type" }, 
{ 
{ "string",   Text.Type },
{ "int",      Int32.Type },
{ "long",     Int64.Type },
{ "real",     Double.Type },
{ "timespan", Duration.Type },
{ "datetime", DateTimeZone.Type },
{ "bool",     Logical.Type },
{ "guid",     Text.Type },
{ "dynamic",  Text.Type }
}),
DataTable = Source[tables]{0},
Columns = Table.FromRecords(DataTable[columns]),
ColumnsWithType = Table.Join(Columns, {"type"}, TypeMap , {"AnalyticsTypes"}),
Rows = Table.FromRows(DataTable[rows], Columns[name]), 
Table = Table.TransformColumnTypes(Rows, Table.ToList(ColumnsWithType, (c) => { c{0}, c{3}}))
in
Table,
    #"Sorted Rows" = Table.Sort(AnalyticsQuery,{{"timestamp", Order.Ascending}})
in
    #"Sorted Rows"

您应该查看表缓冲或直接查询:see this discussion
