Can I find out which program updated the field value?

[James Anton]

For example, the status of db instance was updated by Client Script.
I looked up the syslog_transaction table and found something similar to the time zone when the status was updated. Which of the columns should I look at to know whether the status has been updated by Client Script?
I looked through all the columns but couldn't find it.

If you have logging, you could try by adding the 'context map' field to the log entry form, but you probably won't find the changing of a field in there. The 'what did this and when' isn't easily tracked, unless your script writes it's actions to the log (but I wouldn't do that, for performance reasons). 

Check the history of the record itself to see when the field changed (and maybe an updated by, if it wasn't the system).
