When configuring a Data Collection Rule (DCR) in Azure Monitor to collect Windows Event Logs using the Azure Monitor Agent (AMA), and when you need to filter specific events (like those with a particular Event ID), you must use a filter expression compatible with the data source.
For Windows Event Logs, XPath is the supported query language used to filter specific entries, such as filtering events by ID (e.g., EventID=1001).
