Hello folks around the world!
I have a script that calculates the technical debt of my client, it is in a scheduled job.
I need to know how many resources (specifically memory) this scheduled job uses when running, because so far we have been working with dummy data and we are close to adding a lot of real data, and we need to know how many resources it costs and will cost us to use this script.
Does anyone know of a way to see how much memory is used when running a specific scheduled job?
Any help would be greatly appreciated!

Hello @Aram Sosa ,
Go to "System Logs > Transactions" and and search for the transaction that corresponds to the last run of your job. You can find it by filtering for "URL" = "JOB: {the name of your job}". The Transaction Log record captures a lot of information about the resource usage, e.g. SQL and CPU usage. Memory usage is not captured, though.
But frankly, I wouldn't worry about running out of memory on a standard ServiceNow customer instance, unless your job is doing very expensive things like nested loops on large data sets.
Out of curiosity: how do you calculate "technical debt" using a script?
Regards,
Robert
