Streamstats Question

Engager

Using this query below could you help me identify servers that were added on a daily basis? example today is friday 13th i would like to see new servers that were not on the report on the Thursday the 12th. Alternatively I would like to see servers that were removed.

query - index=#### sourcetype=#### Name="####*"|table Name _time OS LastScanDate|eval Days=round((relative_time(now(),"@d")-relative_time(LastScanDate,"@d"))/86400,0)|eval LastScanDate=strftime(LastScanDate, "%Y-%m-%d")|sort by Name _time|streamstats window=1 current=f global=f values(LastScanDate) as prev|eval John=strftime(LastScanDate, "%d")

Example

Name    _time   OS  LastScanDate    Days    prev
