@Chhaya Vishwakarma​ DBU pricing won't be visible in event log, when you go to your created DLT Job --> Settings --> under Compute (Summary option)--> shows DBU/hr pricing .

If you are creating new job--> u can see pricing summary near compute itself

usually DLT cluster prcicing will depend on whether u enabled photon or not , without photon you see different price and with photon u will see different pricing
