Policy CSP - ADMX_EventLog
Tip
This CSP contains ADMX-backed policies which require a special SyncML format to enable or disable. You must specify the data type in the SyncML as <Format>chr</Format>. For details, see Understanding ADMX-backed policies.
The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see CDATA Sections.

This policy setting controls Event Log behavior when the log file reaches its maximum size and takes effect only if the "Retain old events" policy setting is enabled.
If you enable this policy setting and the "Retain old events" policy setting is enabled, the Event Log file is automatically closed and renamed when it's full. A new file is then started.
If you disable this policy setting and the "Retain old events" policy setting is enabled, new events are discarded and old events are retained.
If you don't configure this policy setting and the "Retain old events" policy setting is enabled, new events are discarded and the old events are retained.
