Hi all.
I am trying to create a kql query to get the AVG of the ingested GBs per month (only billable data). This is the query im building up:
let currentmonth=monthofyear(now());
let month1=union *
| where TimeGenerated > ago(124d)
| where _IsBillable == "True"
| where monthofyear(_TimeReceived)==currentmonth
| summarize TotalGBytes =round(sum(_BilledSize/(1024*1024*1024)),2)
by bin (TimeGenerated, 1d)
| summarize avg(TotalGBytes) by month;
let month2=union *
| where TimeGenerated > ago(124d)
| where _IsBillable == "True"
| where monthofyear(_TimeReceived)==currentmonth-1
| summarize TotalGBytes =round(sum(_BilledSize/(1024*1024*1024)),2)
by bin (TimeGenerated, 1d)
| summarize avg(TotalGBytes) by month;
let month3=union *
| where TimeGenerated > ago(124d)
| where _IsBillable == "True"
| where monthofyear(_TimeReceived)==currentmonth-2
| summarize TotalGBytes =round(sum(_BilledSize/(1024*1024*1024)),2)
by bin (TimeGenerated, 1d)
| summarize avg(TotalGBytes) by month;
month1 | union month2, month3
but getting "'summarize' operator: Failed to resolve scalar expression named 'month'" every time i run the query. Any idea how to solve this situation or any suggestion about how can i get the date i need?
thanks in advance

Solution
The query will be many magnitudes faster if you use the Usage table (which has already aggregated the usage data), rather than trawling through a massive number of records.
If you are not worried about whole month, this is a simple query for each 30d period
Usage
| where TimeGenerated between ( startofmonth(now(),-3).. endofmonth(now(),-1) )
| summarize GBday = sum(Quantity)/1000 by bin(TimeGenerated, 30d)
Go to Log Analytics and run query
TimeGenerated | GBday |
---|---|

2021-01-31T00:00:00Z | 2.716749379860088 |
or to have whole months, maybe this is a start:
union
(
Usage
| where TimeGenerated between ( startofmonth(now(),-3).. endofmonth(now(),-3) )
| summarize GBmonth=sum(Quantity)/1000 , min(TimeGenerated), max(TimeGenerated), month = datetime_part("month", min(TimeGenerated))
),
(
Usage
| where TimeGenerated between ( startofmonth(now(),-2).. endofmonth(now(),-2) )
| summarize GBmonth=sum(Quantity)/1000 , min(TimeGenerated), max(TimeGenerated), month = datetime_part("month", min(TimeGenerated))
),
(

| summarize GBmonth=sum(Quantity)/1000 , min(TimeGenerated), max(TimeGenerated), month = datetime_part("month", min(TimeGenerated))
)
GBmonth | min_TimeGenerated | max_TimeGenerated | month |

Good morning,
I am also trying to find the same information out except that I need to narrow it down by subscription. The query listed runs perfectly for all subscriptions when I run it, however as soon I select 4 individual subscriptions I get an error "'where' operator: Failed to resolve table or column expression named 'Usage' Request id: 323b9391-1abc-4014-ac0c-5435d31b30df"
Could somebody please walk me through the process of how to get this table to populate? If I am correct, I think it means that the table "Usage" does not exist for these subscriptions therefore the query can't pull the data?

Usage doesnt hold the subscription information you need, so you have to revert to the union * command, so it will be slower to run.
union
(
union *
| where _IsBillable == "True"
| where TimeGenerated between ( startofmonth(now(),-3).. endofmonth(now(),-3) )
| summarize GBmonth=round(sum(_BilledSize)/(1024*1024*1024),2), min(TimeGenerated), max(TimeGenerated), month = datetime_part("month", min(TimeGenerated)) by SubscriptionId
),
(
union *
| where TimeGenerated between ( startofmonth(now(),-2).. endofmonth(now(),-2) )
| summarize GBmonth=round(sum(_BilledSize)/(1024*1024*1024),2), min(TimeGenerated), max(TimeGenerated), month = datetime_part("month", min(TimeGenerated)) by SubscriptionId
),
(
union *
| where TimeGenerated between ( startofmonth(now(),-1).. endofmonth(now(),-1) )
| summarize GBmonth=round(sum(_BilledSize)/(1024*1024*1024),2), min(TimeGenerated), max(TimeGenerated), month = datetime_part("month", min(TimeGenerated)) by SubscriptionId
)
Remember its possible for there to be no SubscriptionID so you often get an empty column. If you add in a filter for the subscription you want, it should look like this - please not I haven't tested this very well, so please test and amend.
let findSubIds = dynamic(['sub id 1','sub 2',' Sub 3','']);
union
(
union *
| where _IsBillable == "True"
| where TimeGenerated between ( startofmonth(now(),-3).. endofmonth(now(),-3) )
| where SubscriptionId in(findSubIds)
| summarize GBmonth=round(sum(_BilledSize)/(1024*1024*1024),2), min(TimeGenerated), max(TimeGenerated), month = datetime_part("month", min(TimeGenerated)) by SubscriptionId
),
(
union *
| where TimeGenerated between ( startofmonth(now(),-2).. endofmonth(now(),-2) )
| where SubscriptionId in(findSubIds)
| summarize GBmonth=round(sum(_BilledSize)/(1024*1024*1024),2), min(TimeGenerated), max(TimeGenerated), month = datetime_part("month", min(TimeGenerated)) by SubscriptionId
),
(
