Edge Server Attachment Filter Agent Log Location and Interpretation?

So,

I would like to parse Agent Log for actions of Attachment Filter. Actually, I would create a PowerShell script that would send detailed information about Attachment Filter actions to administrator (me). I have already managed to create reports about actions caused by IP Block List Providers, so it should be similar.

I am aware of:

I need information:

Where are Attachment Filter Agent Logs located on disk?

If it is located in AgentLogYYYYMMDD-nn.LOG file(s) how can I search for Attachment Filter actions (e.g. stripped attachment)?

Thanks!
