Duration of failure over 2 rows - records

Anonymous — Wed, 21 Dec 2022 14:12:30 GMT

Hy,

I got a blackbox file with on a record the failure start datetimestamp (TRUE) en on a other record de failure end datetimestamp.(FALSE). De first failure has a duration of 3 seconds.

How can i calculate the duration for each failure on the locations (Locatie) ?

Thank you.

You can try to create a table with DAX like this:

CalculatedTable =
SUMMARIZE (
'Table',
'Table'[Location],
"Duration",
MINUTE (
CALCULATE ( MAX ( 'Table'[Timestamp] ), 'Table'[Failure] = FALSE () )
- CALCULATE ( MIN ( 'Table'[Timestamp] ), 'Table'[Failure] = TRUE () )
)
)

Hope this helps!

Thank you, I have a summarize per location.

I only changed the Minute in Seconds.

Sure! try this:

SUMMARIZE ( ADDCOLUMNS('Table', "Date", LEFT(CONVERT('Table'[Timestamp],STRING),10)), 'Table'[Location],[Date], "Duration", DATEDIFF(CALCULATE ( MAX ( 'Table'[Timestamp] ), 'Table'[Failure] = TRUE() ) , CALCULATE ( MIN ( 'Table'[Timestamp] ), 'Table'[Failure] = FALSE() ), SECOND) )

I changed the duration calculation to use DATEDIFF function instead, in case you're expecting the failure to last longer than a minute.

If you need to format that, there's a good article that talks about it here:
