How To Produce QLOG files with picoquic

picoquic can produce QLOG compatible files.

To create QLOG files picoquic requires binary logging to be enabled while serving the connection for which a QLOG should be created. Once the connection is closed, the binary log files from client and server can be converted into the QLOG format with the picolog utility.

Create Binary Log File

Command line

Binary logging can be enabled on the command line with the -b parameter. -b expects a path to the binary log file.

Binary logging can be used for clients and for servers.

picoquicdemo -b <path_to_binary_log> [...]

C Interface

Binary logging can be enabled in the C interface by calling picoquic_set_binlog(quic, path) by providing the quic context that should start logging and the path to the binary log file.

Convert Binary Log Files to QLOG

Once the log file has been created, it can be converted using the picolog utility.

Calling

picolog -f qlog <path_to_binary_log>

would create a QLOG file for each connection found in the binary log. If only one connection should be converted, the connection id of that connection must be specified with command line parameter -c.

picolog -f qlog -c <connection_id> <path_to_binary_log>
