Just brainstorming right.  Looking for some sort of solution to Alert (email) individuals when my collected data meets certain criteria.  If some collected feature in a MapService or SDE FC is set to Yes or No, or some other specific value I want to grab that individual record(s) and email it to a few individuals.  


Has anyone done this?  Thanks

It might help to describe where you are stuck, and go from there. Have you started?

For sending email, I'd start here: 18.1.11. email: Examples — Python 2.7.12 documentation

Here's the basic template we use for scheduled task scripts. It includes a lot more than just sending an email but I wanted to show it in context. I have some tweaks planned but this basic structure has served us well for years. We also log the success or failure to a table in SDE so we can report on everything but I left the logging part out.

"""Brief description of script here.

More detailed description of script, dependencies, and purpose.

Followed by a change log.

In reference to your question about monitoring data for certain criteria, you could schedule this script as a task in Windows for whatever interval you need. The script could check for your conditions and only send the email if the conditions are met.
