Hi,

I'am sending some events each minute to Splunk :

 

TIMEIDINOUT
08:00A10
08:00B00
    
08:01A21
08:01B22
08:01C40
    
08:02A33
08:02B32
    
08:03A64
08:03B33
    
08:04A64
08:04B33
08:04C42
    
08:05A64
08:05B33
08:05C42

 

What i'am trying to get as a result is :

TIMESUMIN - PREVIOUS_SUMINSUMOUT - PREVIOUS_SUMOUT
08:00=1+0 = 1=0+0 = 0
08:01=2+2+4 - (1+0) = 7=1+2+0 - (0+0) = 3
08:02=3+3 - (2+2+4) = -2=3+2 - (1+2+0) = 2
08:03=6+3 - (3+3) = 3=4+3 - (3+2) = 2
08:04=6+3+4 - (6+3) = 4=4+3+2 - (4+3) = 2
08:05=6+3+4 - (6+3+4) = 0=4+3+2 - (4+3+2) = 0

 

After that i need to plot the two columns using a timechart by TIME

 

Any hints are welcome.

 

Thank you guys
