Debug block for the message passing system.
The message debug block is used to capture and print or store messages as they are received. Any block that generates a message may connect that message port to one or more of the message input ports of this debug block.
The message ports are, if not showing the extended logging levels
- log (new in 3.11)
- Uses the GNU Radio logging system to print the message contents. This is probably the input you want.
- Prints the message directly to standard out; verbose, not logged to any configured logging backends. You can suppress the printing of PDU data blob contents with the "Print PDU contents" option.
- store
- Stores the message in an internal vector. It works in conjunction with a
message_debug::get_message(size_t i)call that allows us to retrieve messageiafterwards. - print_pdu (deprecated since 3.10, might be removed)
- Print the contents of the PDU (if a PDU)
Parameters
- Print PDU contents
- Prints a hexdump of the contents of PDUs; if not set, only print the meta description and length
- Log level (new in 3.11)
- sets the log level to trace, debug, info, warning, error or critical
Example Flowgraph
This program illustrates the usage of two messages debugs to log things at different log levels.
yielding this output:
