Is there a possibility in Splunk to get data like below :
If a condition is true then that data is to be printed in table
If (a $lt; b)
eval c=round(((b-a)/b)*100),0)
print c (in table format)
Or else just a message on full screen that with "no change".
@dkdeepshikhaa if there are multiple events in your query your conditional evaluation will be based on each event. You can get no change text in table with below query-
<your search>| eval var=round(((b-a)/b)*100),0) | eval c = if(a<b,var,"no change") | table c
