Ideally, you have a timestamp and message columns in the eventlog, you could use this to calculate the time taken.
For example, to calculate the time taken to allocate resources, you could use a function such as datediff to calculate the difference in the timestamps of 2 records, check the snip below:
Similarly, for time taken to execute each table, you would have a message as `<Table_Name>` is RUNNING and `<Table_Name>` is COMPLETED. Get the difference between the timestamps.
