Trace log files

Trace log files are compressed files in the /tmp/mmfs directory. The contents of a trace log file depends on the type of trace.

The product supports four types of tracing: SMB, Network, and Winbind.

SMB: SMB tracing captures System Message Block information. The resulting trace log file contains an smbd.log file for each node for which information is collected and for each client that is connected to this node. A trace captures information for all clients with the specified IP address.
Network: Network tracing uses tcpdump utility to capture network packets. The resulting trace log file contains a pcappng file that is readable by Wireshark and other programs. The file name is similar to bfn22-10g_all_00001_20150907125015.pcap.
If the mmprotocoltrace command specifies a client IP address, the trace captures traffic between that client and the server. If no IP address is specified, the trace captures traffic across all network interfaces of each participating node.
