Chapter 3      Understanding Intrusion and Correlation Data Structures 
  Intrusion Event and Metadata Record Types
The following table describes the fields in the FireAMP File Type record.
Correlation Event for 5.1+
Correlation events (called compliance events in pre-5.0 versions) contain information about correlation 
policy violations. This message uses the standard eStreamer message header and specifies a record type 
of 112, followed by a correlation data block of type 128 in the series 1 set of data blocks. Data block 
type 128 differs from its predecessor (block type 116) in including IPv6 support.
You can request 5.1+ correlation events from eStreamer only by extended request, for which you request 
event type code 
31
 and version code 
8
 in the Stream Request message (see 
 for information about submitting extended requests). You can optionally enable bit 
23 in the flags field of the initial event stream request message, to include the extended event header. 
You can also enable bit 20 in the flags field to include user metadata.
