Hello world. What’s the best method to use to see when every script was last run?

Script execution logs

Problem is that it only logs 10k rows and get purged. Maybe that gives me an accurate answer. But I can only find 97 of the 800 records that are deployed

You might want to consider using a service called splunk. You can add logging to your scripts that will push those logs outside of NetSuite and keep a much much longer list of log entries that are also searchable.

Strongpoint would also help you with this, @Felix Divall. I don't know which would be the more cost effective option
