Total count of events occuring within specified duration

[stillmakinnoise]

I'm brand new to this, so hopefully my explanation is clear enough. Please let me know if additional explanation is required! 

I have four columns within my data: Device ID, Event Type, Event Date, and Event Time. I'm looking for a count of when three specific Event Types (i.e. Event Type 1, 2, and 3) occured on the same Device ID within a specify duration of time (e.g. 30 seconds).  

For example, on 1/1/2017, Event Type 1 occured on Device ID 1 at 5:15:25, and Event Type 2 occured on Device ID 1 at 5:15:34 and Event Type 3 occured at 5:15:45. I'd like to know the total times this happened on any device. The combined occurence could be defined as a new Event Type. 

Thanks in advance to anyone who can assist!

Hi @stillmakinnoise,

Based on your description, you want to get the total count to specific time range and group by device Id, right?

If this is a case, you can try to use below formula:

Measure:

Total Count of Speicfic Range =
VAR current_device =
    LASTNONBLANK ( table[deivce id], [device id] )
VAR current_date =
    MAX ( table[Event Date] )
RETURN
    CALCULATE (
        COUNTROWS ( table ),
        FILTER (
            ALL ( table ),
            [device id] = current_device
                && [Event Date] = current_date
                && [Event Time] >= min_Range
                && [Event Time] <= max_Range
        )
    )

If above not help. please share some sample data and detail contents to help us clarify your requirement.

Hi @Anonymous and thanks for your reply! Below is a sample of the data, which I probably should've included in the first place! 

deviceid	Event Type	Event Time	Event Date
A Door 30	Forced	7:35:56 AM	1/1/2017
A Door 30	Forced	7:36:00 AM	1/1/2017
B Door 10	Invalid	7:36:10 AM	1/1/2017
D Door 61	Push	7:37:49 AM	1/1/2017
A Door 61	Unlocked	7:38:07 AM	1/1/2017
A Door 61	Forced	7:38:16 AM	1/1/2017
T Door 1	Invalid	7:40:16 AM	1/1/2017
O Door	Unlocked	7:46:04 AM	1/1/2017
A Door 12	Invalid	7:46:27 AM	1/1/2017
T Door 1	Invalid	7:46:42 AM	1/1/2017

What I'm looking to identify is the number of times the three bolded Event Types occur on the same deviceid within 60 seconds of one another's Event Time on the same Event Date, as is demonstrated in the table.

Hi @stillmakinnoise,

I modify the formula to let it works on sample data, please try it if it works on your side.

Measure:

Total Count of Speicfic Range = 
VAR current_device =
    LASTNONBLANK ( 'Table'[deviceid], [deviceid] )
VAR current_date =
    min(  'Table'[Event Date] )
VAR current_time =
    min ( 'Table'[Event Time] )
RETURN
    CALCULATE (
        COUNTROWS ( 'Table' ),
        FILTER (
            ALL ( 'Table' ),
            [deviceid] = current_device
                && [Event Date] = current_date
                && [Event Time] >= current_time
                && [Event Time] <= current_time + 60
        )
    )

Hi @stillmakinnoise,

With respect to the dataset that you have posted, what exact result are you expecting?
