SOME/IP Monitoring

SOME/IP monitoring is used to collect and record communication data exchanged in an Ethernet group.

The SOME/IP message data is based on AUTOSAR description files. A description of the Ethernet communication is necessary to measure signals from the Ethernet. INCA supports the description formats AUTOSAR (*.arxml). These description formats read the description of the Ethernet environment.

SOME/IP monitoring uses serialized data to obtain information from the messages of the Ethernet environment. E2E protected frames are supported.

Serialized data have the following characteristics:

Contain one implementation data type per message
Are similar to C structs
Use padding bytes for alignment
Allow dynamic length elements
Can contain additional length fields for static data

INCA can not measure all data types. It skips dynamic data types like length arrays and strings.

System Limits

UDP, IPv4, and IPv6 (without extension header)
Basic data types (bool, unit8 (16/32/64), sint8 (16/32/64), float32 (64)), structs, unions, and fixed size arrays
