Delta over Multiple SIDs

[markschoonover]

In my raw data I have a lot of values for a field called "sid". For each of those values I want to calculate the delta of another field "Number" from the previous value for that sid. Then I need to do a little eval on it and then timechart the values for each sid. For each of those values I want to calculate the delta of another field "Number" from the previous value for that sid. Then I need to do a little eval on it and then timechart the values for each sid.

Basically I want to do this:

index=foo sid=="bar" | delta p=2 Number AS num | eval num=abs(num/300) | timechart avg(num)

BUT that just does the work for one sid "bar". I want to do it all in one search for all values of "sid", ie and get that sid="bar" out of there.

I've tried the foreach command but I'm doing something wrong because I keep getting an error like "none streaming commands not allowed"

@markschoonover, can you add some sample data (mocked) for foo and bar that should be correlated?

Following run anywhere search samples daily data with sid foo and bar and incremental Number field.

You can use streamstats command to compare current sid with previous one. However, streamstats requires that your data is sorted by sid and _time. Since streamstats evaluates events in streaming manner you can use current=f and window=1 to get the previous value of Number. PS: If you dont sort by _time (this example uses ascending data), you might get the Next value instead of Previous.

|  append 
    [|  makeresults
|  eval _time=strptime("2017/11/02","%Y/%m/%d"), sid="foo", Number=12212]
|  append 
    [|  makeresults
|  eval _time=strptime("2017/11/03","%Y/%m/%d"), sid="bar", Number=12546]
|  append 
    [|  makeresults
|  eval _time=strptime("2017/11/05","%Y/%m/%d"), sid="foo", Number=12241]
|  append 
    [|  makeresults
|  eval _time=strptime("2017/11/06","%Y/%m/%d"), sid="foo", Number=12371]
|  append 
    [|  makeresults
|  eval _time=strptime("2017/11/07","%Y/%m/%d"), sid="foo", Number=12497]
|  append 
    [|  makeresults
|  eval _time=strptime("2017/11/08","%Y/%m/%d"), sid="bar", Number=12876]
|  table _time sid Number
|  sort sid _time
|  streamstats current=f window=1 values(Number) as Prev by sid
|  eval num=round((Number-Prev)/300,1)
|  fillnull value=0 num
|  timechart span=1d avg(num) as num by sid

PS: I have used span=1d since I have daily data mocked, you should change as per your data. Command till | table ... are used to mock some sample data. In case the provided query does not work you would need to provide some sample data with Number field values and _time (since based on your current query and explanation seems like sid always increases for each sid.

Please refer to documentation for more details on streamstats: http://docs.splunk.com/Documentation/Splunk/latest/SearchReference/Streamstats
