Hi Ramesh,
Please find the answer below:
The avg_runtime attribute defines an average run time (in minutes) for a job that is newly submitted to the database. The attribute is used when the job has not run.
This will set an expectation for a new job to understand what is expected average run time.
We have AAI - Automation Analytics & Intelligence which can give more statistics on job executions and latencies which help analyze more accurately.
