Field - transaction_response_time_variance
Variance of the transaction RT times
The field is created using the following pseudocode:
numerator = transaction_squared_sum_time - (transaction_total_time ** 2 / transaction_total_count)
transaction_response_time_variance = numerator / (transaction_total_count - 1) * 1024 / 1e9
valid_filter = (transaction_total_count > 5) & (transaction_response_time_variance < 1) & transaction_response_time_variance.notna()
return transaction_response_time_variance.where(valid_filter, 0)
